Sinn Spezialuhren zu Frankfurt am Main

Classic design language meets functional design: The 104 Classic 12 stands for individual style with technically superior features. At its core is the small seconds display, elegantly showcased on a chamois-coloured subdial with fine grooves and polished chamfers. The hour-ratcheting pilot’s bezel with a ceramic inlay enables a second time zone, offers outstanding scratch resistance and is securely captive within the case, true to the proven SINN technology standards. One of the most renowned design awards in the world, the German Design Award is highly respected in and beyond professional circles. Only those products with demonstrably outstanding design qualities are selected to participate in the competition after undergoing a rigorous nomination procedure.

We are delighted to have received the ‘Best Sustainable Watch’ award at the TEMPORIS International Awards 2025 ceremony held at the Kongresshaus Zurich. The U16, made from steel from the eponymous U 16 submarine of the 206 class, has a history that inspires marine enthusiasts and watch lovers alike – this convinced both the jury and the watch enthusiasts who were called upon to vote publicly. Hailed as the ‘Golden Globes of watchmaking’, the gala achieved unprecedented global reach, thrilling over 10 million individuals from more than 80 countries in Europe, Asia, Africa, North and South America and Australia, with more than 350,000 people actively participating in the public vote.

The 903 model series is presented in a technically completely revised version. We use hybrid ceramic luminous elements for the indices, which are meticulously attached by hand, the number 12 and the hour and minute hands. The result: extreme brightness and perfect readability in the dark. The redesign of the case has a bezel which can be smoothly operated from the outer diameter of the watch. The impressive water resistance of 20 bar testifies to a feat of engineering that has long shaped the SINN brand. The 903 St II also impressed the readers of the specialist magazine Armbanduhren and the portal armbanduhren-online.de and was voted watch of the Year 2025.

Since the summer of 2015, our company has been represented with its own SINN Römerberg Branch on the prestigious Rathausplatz, right in the heart of Frankfurt’s Old Town. For our customers in Frankfurt, this location offers an attractive alternative to the showroom at company headquarters. Visitors from outside the city can combine the purchase of their SINN watch with a leisurely stroll through the city center – without having to leave it. In addition to sales and consultation, our staff at the Römerberg location also handle service requests in the dedicated sales and workshop areas. To mark the anniversary, we are releasing the 1739 Römerberg model.

The special edition 6099 Anniversary, limited to 250 pieces on the occasion of the 25th anniversary of the Frankfurt Financial District Watches, embodies timeless elegance, technical sophistication and a special connection to the city of Frankfurt, where the company has its headquarters. The galvanised silver-plated dial with a sunburst decoration was used for the first time in this model series. The display of the three time zones on a 12-hour basis makes it possible to keep an overview at all time in a globalised and networked world economy. These and other features impressed the jury of the iF Design Award, which presented the 6099 Anniversary Chronograph with the prestigious iF DESIGN AWARD 2025.

For the 20th anniversary of our U-Series diving watches, three special models are introduced in 2025: the U15, U16, and U18. Their watch cases carry a unique history, as they are made from a special type of steel originally sourced from the decommissioned German Navy submarines U 15, U 16, and U 18. By repurposing this submarine steel in the spirit of sustainability, we not only enhance its value but also create an exclusive emotional connection to these anniversary models.

In recognition of his entrepreneurial responsibility and with the desire to secure his life’s work, Lothar Schmidt – owner and managing director of Sinn Spezialuhren since 1994 – has established the UWE Foundation. A central focus is ensuring the long-term continuity of the company, in line with preserving it as a unified entity and preventing its sale to “speculators” in the spirit of so-called "locust capitalism." Mr. Schmidt chose the name of the foundation after his son Uwe, who, due to illness, is unable to assume the inheritance. Some of the foundation’s purposes align with UNESCO’s mission to preserve World Heritage (abbreviated as UWE in German) for future generations. This fundamental idea – the preservation of nature and cultural heritage – reflects Mr. Schmidt’s own vision for the foundation’s mission. Thus, the foundation's name carries a dual symbolic meaning. The general purpose of the foundation is to promote science and research, art and culture, as well as nature conservation and landscape preservation. Its mission is realized in particular through: 1. Promotion of craftsmanship and watchmaking; 2. Preservation and promotion of the German language; 3. Support for music and performing arts; 4. Conservation and care of traditional orchard meadows

The 1st of September marks the 30th anniversary of the company takeover by the current owner Lothar Schmidt, which is a tantamount to founding a new company. Little by little, Lothar Schmidt makes strategically important decisions, such as the expansion of distribution channels through depots. In the 30 years under his leadership, numerous brands and patents were developed and and registered. A high level of expertise in terms of material technology and the desire to offer customers the best possible technical product, technologies and new products in SINN's own design that have a lasting impact on development and manifest the international success of the brand.

n front of the headquarters of Sinn Spezialuhren in Frankfurt stands an impressive piece of maritime history: the propeller of the former submarine U 15, weighing approximately 1.1 tons. This exhibit is not only a remarkable example of German engineering, but also a symbol of the close connection between the world of submarines and SINN’s timepieces. Since 2005, Sinn Spezialuhren has used German submarine steel to produce particularly robust and resilient diver’s watches. In 2025, SINN’s expertise in materials will reach a new peak with the presentation of the U15, a diver’s watch crafted from the very steel of the decommissioned submarine U 15. This creates a unique fusion of maritime history and cutting-edge watchmaking, highlighting the company's innovative strength. The propeller of U 15 in front of Sinn Spezialuhren's headquarters is thus far more than a technical relic – it is a symbol of tradition, innovation, and the extraordinary material expertise that makes SINN so unique in the world of horology.

Diving watches must offer perfect legibility in all lighting and water conditions, along with exceptional durability. The U50 HYDRO series – comprising the U50 HYDRO, U50 HYDRO S, and U50 HYDRO SDR – is equipped with HYDRO Technology and meets all these requirements. These timepieces are reflection-free under water from any angle, absolutely free from foggingf, and – thanks to a special oil filling – water- and pressure-resistant to a diving depth of 5,000 meters (500 bar).

A unique combination of past and present: this is the essence of the unmistakable charm of the historic pilot's chronograph 156.1 with the in-house SZ01 SINN-chronograph movement. The timepiece has a jumping 60-minute stopwatch hand from the centre and a captive pilot’s bezel made of stainless steel with Black Hard Coating on a TEGIMENT Technology basis, which proves it´s innovative character. One of the most renowned design awards in the world, the German Design Award is highly respected in and beyond professional circles. Only those products with demonstrably outstanding design qualities are selected to participate in the competition after undergoing a rigorous nomination procedure.

For the first time, we present a watch whose case is made from TITANIUM DAMASCUS (TITANDAMST), once again demonstrating our expertise in working with extraordinary materials. The traditional manufacturing process of TITANIUM DAMASCUS is extremely elaborate and presents several challenges, especially in the forging technique. This is because Titanium Grade 2 and Titanium Grade 5 exhibit a significant difference in terms of their mechanical strength. Pure Titanium Grade 2 flows more easily compared to the tough and high-strength Titanium Grade 5. During the forging process, Titanium Grade 2 practically flows out between the layers of Titanium Grade 5 alloy. This requires exceptional attention and craftsmanship. A masterpiece of blacksmithing, delivered in unparalleled quality and with timeless, elegant aesthetics. At the same time, our model 1800 TITANDAMASZENER represents the ultimate fusion of cutting-edge technology and traditional watchmaking craftsmanship.

The outstanding quality and design of the 356 PILOT Classic W model impressed the international jury of experts. The classic chronograph with bicompax display and black, electroplated matt-silk counters also bears the decorative "FLIEGER KLASSIK" lettering. The dial in matt-silk white ensures timeless elegance paired with clarity. The Red Dot Award is one of the largest design competitions in the world and a recognised award for high design quality. Only products with an outstanding design receive this seal of quality from the international jury.

For the first time, Sinn Spezialuhren is using the in-house developed bronze alloy "Goldbronze 125" for its captive safety diver's bezel. The result: the T50 GBDR harmoniously combines robustness with refined elegance, appealing to professional divers and watch enthusiasts alike. The watch is proof of precision engineering and innovative design that guarantees both durability and aesthetics, according to the expert jury. The iF Design Award has been an internationally recognised hallmark of design excellence since 1954. It is one of the most important design prizes in the world and is awarded once a year by the oldest independent design institution, iF International Forum Design GmbH.

We are celebrating this anniversary with two special editions of our Frankfurt Financial District Watches, limited to 250 pieces: 6000 Anniversary III with a diameter of 38.5 mm and 6099 Anniversary with a diameter of 41.5 mm. Both models are characterised by the galvanic silver-plated dial with a sunburst decoration, which was implemented for the first time in this model series. The display of the three time zones on a 12-hour basis makes it possible to keep an overview at all times in a globalised world economy. A glance at the finely finished movement through the transparent case back made of sapphire crystal reveals the artful mechanics of the column-wheel chronograph, as well as the rotor engraving of the Frankfurt skyline with an individual limited edition number.

The 356 PILOT Classic AS E combines functionality with stylish design. The bead-blasted case, shock-proof acrylic glass and solid back of the 356 model are classic characteristics of a pilot's watch. The visual coordination of the ivory-coloured hands and numerals on the colour gradient dial gives the watch its vintage flair. In addition, the model impresses with its suitability for everyday use, as the watch is water- and pressure-resistant up to 10 bar as well as being low pressure resistant. One of the most renowned design awards in the world, the German Design Award is highly respected in and beyond professional circles. Only those products with demonstrably outstanding design qualities are selected to participate in the competition after undergoing a rigorous nomination procedure.

The 356 PILOT Classic Anniversary model with Bicompax display, limited to 500 pieces, is being released to mark the occasion. For the first time in this model series - as a special tribute and refinement - the dial at six o'clock bears the unmistakable ‘FLIEGER KLASSIK’ lettering. As a counterpart to this, the SINN logo is applied as an applique at 12 o'clock. Watch enthusiasts can also look forward to the 356 FLIEGER Klassik AS E and 356 FLIEGER Klassik W models.

On September 27, a classical concert will be held for the first time in the Atrium at our Frankfurt headquarters. The twin sisters Auguste and Ieva Petkunaite from Lithuania will perform piano works by Mozart, Schubert, Ravel, and Czerny. This event reflects our company’s explicit commitment to supporting emerging classical musicians. The Atrium is perfectly suited for this purpose, as owner Lothar Schmidt originally designed the space as a concert hall. Thanks to its excellent acoustics, it provides an ideal sound environment. Furthermore, the “promotion of the use and preservation of music and performing arts” is firmly anchored in our company’s mission and has long been part of Lothar Schmidt’s active cultural engagement.

Goldbronze 125 (CuSn7Au12.5) is a bronze alloy developed and patented by Sinn. The gold bronze produced in a multi-stage alloy process has an exceptionally high degree of purity. Compared to conventional bronze alloys, the special degree of purity results in improved skin compatibility and increased corrosion resistance to seawater. The tendency toward chemical reactions in the case of non-magnetic Goldbronze 125 is counteracted by an alloyed gold finish. Goldbronze 125 continues to develop a darkening of the surface due to oxidation, also known as a patina. However, the alloy achieves a higher degree of inertness in the face of environmental influences than ordinary bronze because it has gold as a component. If desired, the mentioned darkening of the surface can be removed with a gold bronze cleaning cloth provided that the oxidation is minimal enough. Goldbronze 125 is a registered trademark. It is used on our T50 GBDR and T50 GOLDBRONZE models.

For the second time, a Sinn watch was awarded the renowned design prize and fulfilled the demanding evaluation criteria. In contrast to other awards, the winners of the iF Design Award are determined on the basis of detailed questions in the categories of idea, form, function, differentiation and impact. These categories in turn form the basis for a points system. Sinn Spezialuhren achieved 285 out of 500 possible points with the 105 St Sa UTC W model. The 105 St Sa UTC W convinced the 133-member, independent, international jury of experts with its innovative combination of technical, sporty looks and a multitude of functions. The iF Design Award has been an internationally recognised trademark for outstanding design since 1954. It is awarded once a year by the world's oldest independent design institution, iF International Forum Design GmbH.

Founded in 1961, the traditional company Sinn Spezialuhren combines quality, precision and innovation in its masterfully crafted watches. This also applies in particular to the choice of materials used. For the new 1800 S GG DAMASZENER, limited to just 100 pieces, genuine fire-welded Damascus steel was used, which, with its distinctive and unique grain, gives the noble watch its own unmistakable identity. In combination with the clear, masculine design language and hands and appliqués made of 18 ct gold, an exclusive watch was created that is an eye-catcher on every wrist.

In opening this branch, Sinn Spezialuhren is seeking not only to enhance its customer service operation but also to expand the overall service. This is a strategically expedient step in view of the fact that the region is characterised by its traditional watchmaking industry and thus has a correspondingly high number of qualified specialists. In this respect, the administrative management and processing for the customer service operations performed in Dresden will be handled through the headquarters in Frankfurt am Main.

Three watches from Sinn Spezialuhren have previously won a Red Dot Award in the ‘Product Design’ category. The latest winner, the 1739 Ag B, has shown its excellent design quality by meeting the strict criteria of the jury. The experts all agreed on one thing: a stylish watch should have a distinctive look combined with a function-orientated design. And this watch certainly follows the idea of combining elegance with suitability for everyday use. The Red Dot Award is one of the biggest design competitions in the world. In 2022, designers, design agencies and manufacturers from around 60 countries submitted their products for the award. 48 international jury members examined these products expertly, individually and meticulously. Only products with outstanding design quality receive the award.

Erstmalig wird eine Sinn Uhr mit dem hochwertigen Designpreis ausgezeichnet und erfüllt die anspruchsvollen Bewertungskriterien. Im Unterschied zu anderen Awards werden beim iF Design Award die Bestprämierten auf Basis von detaillierten Fragen in den Bereichen Idee, Form, Funktion, Unterscheidung und Auswirkung ermittelt. Diese Kategorien wiederum sind Basis für ein Punktesystem. Mit dem Modell 717 konnte Sinn Spezialuhren 300 von 500 möglichen Punkten erzielen. Den Preis erhält damit eine Uhr, für die in Sachen Design, Form und Funktion die historische Borduhr Nabo 17 ZM als Inspiration diente. Seit 1954 ist der iF Design Award ein international anerkanntes Markenzeichen, wenn es um herausragendes Design geht. Der Award wird einmal im Jahr von der weltweit ältesten und unabhängigen Designinstitution vergeben, der iF International Forum Design GmbH.

Mission timers are watches equipped with the necessary functions to suit the specific demands of their mission. Since 1997, they have been united by one common principle of construction and design: form follows function, with a focus on the key essentials in terms of outstanding readability and rapid time recording. 2022 marks the 25th anniversary of these robust timepieces. Limited to 500 pieces, the EZM 1.1 S featuring SINN movement SZ01 and a 60-minute stop function from the dial centre honours the occasion.

The panel of experts are unanimous in their decision to rightfully award this watch the German Design Award. Model 717 combines the functions of the historical Nabo 17 ZM navigation cockpit clock with the wearer comfort of a sporty wristwatch. With its deep black case and matching leather strap, the cockpit wristwatch has a timelessly elegant and extraordinarily high-quality design. This fascinating and exclusive timepiece ever so stylishly links the past with the future and perfectly embodies our brand’s DNA down to the last detail.

Eleven outstanding timepieces are awarded trophies at the fourth Capital Watch Awards. Watchmakers submit a total of 200 models in advance to Germany’s most successful business magazine. Each brand can only enter one watch, with 33 ultimately reaching the finals. A top-class jury of watch experts – as well as decision makers and creatives from other industries – ultimately determines the respective winners in eleven different categories. Our 103 Classic 12 model takes first place in the category for watches up to 5,000 euros. This edition offers a contemporary interpretation of a classic design.

On 2 October, at Paderborn/Lippstadt airport, around 1,000 spectators gaze spellbound into the grey and cloudy skies. Crunch time comes at 4 p.m.: the world record attempt by the Cypres Demo Team, an outfit consisting of seven level professionals at international level, is a success – the flying of a 6,418.12-square-meter German flag during a skydive. A phenomenal performance that officially seals their return to the Guinness Book of Records for the first time since 2017. Sinn Spezialuhren is there from the start, too – as every skydiver sports their very own SINN timepiece on their wrist for the special event.

For the third time in a row, one of our timepieces receives the Red Dot Award, which is only bestowed on products with an outstanding design.The jury’s award decision was thus based on the fact that the 105 St Sa UTC combines distinctive design elements with a high level of functionality that reflects the mobile lifestyle of modern day people. The “Red Dot Award: Product Design” honours the best products developed each year. The evaluation criteria for identifying well-designed and innovative products include formal quality, ergonomics and durability.

The 104 St Sa I A receives the German Design Award in the category ‘Excellent Product Design 2021’ for its outstanding design. The clear structure, which ensures optimum readability of the time, date and weekday display, characterises this classic pilot watch. A distinctive feature of this timepiece is the anthracite dial with sunburst decoration, which highlights the timeless character of the watch. The panel of experts confer the award in recognition of these elements, the consistent design concept and its implementation.

Our company is 60 years old. In honour of this occasion, we are releasing a limited edition of 600 timepieces with unique numbering in the form of the 144 St S Anniversary II. The sports chronograph stands in a long line of tradition: the first model was launched in 1974. The anniversary edition is a fine example of how the company is constantly continuing to develop its classic timepieces. This timepiece has thus been equipped with a wide range of technical features, finished with a black hard coating and has a new silicone strap with integrated case.

The bicompax chronograph 936, featuring the chronograph movement SZ05 designed in-house, is awarded the Red Dot Award in the category ‘Product Design 2020’ during the renowned design competition. The international jury prizes the excellent design quality and incomparable design of the product. This award is further proof for us that outstanding design quality and uncompromising functionality are mutually dependent rather than mutually exclusive.

The EZM 12 and the HUNTING WATCH 3006 are awarded ‘Excellent Product Design 2020’ by the German Design Award, which sets the highest of standards for award winners. Consequently, the award is only given to products with an outstanding design. An international panel of judges chooses a winner from amongst the 500 preselected products. The award strengthens our belief that we should continue to develop and design our watches exclusively for their specific purpose.

“The dynamic and sporty design of the EZM 12 is remarkable. Its special properties for emergency medical care are functionally impressive.” This is the reason given by the panel of judges for awarding the EZM 12 the Red Dot Product Design Award. The Red Dot Award is one of the biggest design competitions in the world. 5,500 products from 55 nations are entered in various categories in 2019. Our company takes part for the first time, making us even more thrilled to receive this award. It is impressive proof that the principles on which the development of our timepieces are based hold true.

Owner Lothar Schmidt, an engineer, has successfully managed the Sinn Spezialuhren company since 1 September 1994. His most notable achievements include the development of technologies and the Frankfurt Financial District Watches, initiation of the DIN 8330 standard for timekeeping technology in pilot watches, continuous global growth, the move to the new headquarters in Sossenheim and many other company advancements. Thanks to his management success, Sinn Spezialuhren is well equipped for future challenges and has established itself as a high-quality watch brand, popular with countless watch lovers. This photo (left) shows Lothar Schmidt with four of his employees, who have also been with our company since 1994 or even longer.

On 2 September 1999, Lothar Schmidt presented a unique timepiece at the Museum für Vor- und Frühgeschichte in Frankfurt: the Frankfurt Financial District Watch 6000. This watch would be the first in a line of traditional watches that have formed an integral part of our watch collection for 20 years. At the same time, the first-ever lettering to appear on the dial – ‘Frankfurt am Main’ – demonstrates our connection to the city in which our company has been based since 1961.

Our company is well known for the fact that we often use extraordinary materials. One successful example is the 1800 DAMASZENER, a limited edition of 100 watches, which we introduced to the public in 2018– a watch made from genuine forge-welded Damascus steel and manufactured using a traditional forging technique. For the first time, different high-grade stainless steels were layered and forge-welded together during production. We also used a combination of high-grade stainless steels to create the Damascus steel for both the crown and the bow and pin buckle. The watch also boasts a uniqueness that is immediately reflected in its design and appearance. For in order to perfectly enhance the characteristic texture of Damascus steel – an organic pattern of alternating bands of light and dark – the one-piece dial and central part of the case were forged from a complete steel block rather than designed as separate components, as is customary. The Damascus pattern on the dial continues across the entire case to create a fascinating and impressive whole. The surface of the case is also hardened using TEGIMENT Technology, making it especially scratch-resistant.

Many partners of our nationwide distributors accepted our invitation to join us as we inaugurated our new headquarters on 4 February 2018. To mark the special occasion, we presented two extraordinary watch editions: the 756 II and 757 II as well as the 756 III and 757 III models, each a limited edition of 75. What distinguishes these watches is the fact that they were the first collection that our distribution partners exclusively were able to order quite some time before the official release – a privilege which underlines the importance of our partnership with established retailers. The demand among distribution partners was correspondingly high, leaving few watches for us to sell through our direct marketing.

The former pilot and blind-flying instructor founded our company under the name ‘Helmut Sinn Spezialuhren’ in 1961 and helped shape it over many years. It is with the utmost respect that we remember Helmut Sinn’s extraordinary and strong-willed personality, his creativity and dynamism, his energy and his sense of humour. The highest tribute must be paid to his achievements as an entrepreneur and as the founder of Helmut Sinn Spezialuhren, the company that laid the foundations for the one we know today. We will always have very fond memories of Helmut Sinn.

On 1 September, we move into our new headquarters in Sossenheim. The move from our previous location in Frankfurt-Rödelheim, where we were based since 1985, marks a key milestone in our company’s history. The change of location is needed for us to be able to continue the company’s positive development in future, too. In addition to producing high-quality timepieces that are then sold directly in a spacious salesroom, the Sossenheim location also deals with customer service. Visitors are able to view the entire collection first-hand.

The EZM 1, which in 1997 was the first mission timer we developed for the special units of the German police department and customs authority, marked the dawn of an impressive era. As reliable, robust and accurate as an instrument, our mission timer is now available for a whole host of professional users, always specially developed to meet the requirements of the application. These include pilots, divers, firefighters, emergency doctors, rescue workers, special units of the German police department and armed forces such as the GSG 9, Germany’s commando frogman force KSM (Kommando Spezialkräfte der Marine), and the special unit of the German Central Customs Support Group ZUZ (Zentrale Unterstützungsgruppe Zoll). Despite all their differences, these users all have one thing in common: they rely on the exceptional performance of our watches on a daily basis – particularly in critical situations.

Four anniversary watches mark the occasion: the 556 Anniversary (limited to 1,000 pieces), the 910 Anniversary (limited to 300 pieces) and the 6200 Meisterbund I and 6200 WG Meisterbund I, both limited to 55 pieces.

A timepiece boasting two extraordinary features. For in addition to a stopwatch, it also features a split-seconds mechanism for recording intermediate times. The historical value of an additional feature adds to its appeal. The 910 Anniversary features a column wheel chronograph that stops the time. The column wheel control mechanism has been a key component in traditional chronographs since the mid 1900s. To commemorate the 55th anniversary, the limited-edition number and the years ‘1961–2016’ are engraved on the case back.

Three masters of their trade – Sinn Spezialuhren, Sächsische Uhrentechnologie Glashütte (SUG) and Uhren-Werke-Dresden (UWD) – come together for an exciting project in which all key watch components are made in Germany. For the 6200 Meisterbund I and the 6200 WG Meisterbund I, both limited to 55 pieces, SUG is responsible for building and manufacturing the case made of 18-carat rose Gold, respectively white gold. Our company shapes the ‘face’ of the watch in line with our traditional masterpieces. And UWD is responsible for manufacturing the high-quality hand-wound calibre UWD 33.1 – a development that we have been accompanying for some time now and that has been reliably used in a watch for the first time in series production.

As a reminder of the laying of the foundation stone on 31 July 2015, a time capsule will be buried in the new building in Frankfurt-Sossenheim and the spot marked with a memorial plaque. Both are reminders of how significant the new building is for the future of Sinn Spezialuhren. To keep the memorable date alive, among other things the Frankfurt Financial District Watch personally belonging to the company owner, Lothar Schmidt, will be sealed in the time capsule along with current newspapers and magazines, as well as the company cata­logue.

For the first time in decades, the German Institute for Standardisation (DIN) will publish a new German watch standard in March 2016: DIN 8330 “Timekeeping technology – pilot watches”, which is based on the technical standard for pilot watches (TESTAF) initiated by us. The impetus to develop the standard also comes from SINN. DIN 8330 means that the defined requirements for TESTAF are standardised, precise, systematic and up to date. In line with the DIN 8306 standard for diver’s watches, it meets the requirements and testing criteria for functionally demanding, safe and reliable pilot watches. Building on TESTAF, in addition DIN 8330 widens the pool of certifiable watches (mechanical watches are now eligible as well as quartz watches) and features more stringent test criteria for readability, vibration stresses and resistance to liquids commonly found in aircraft, among other things.

September 2016 marks the 20th anniversary of the German special forces command, KSK (Kommando Spezialkräfte). In honour of the occasion, we team up with the Gemeinschaft Deutscher Kommandosoldaten e.V. (association of German commando soldiers) to develop the ‘K212 Special Forces Command’, a 70-piece special limited edition exclusively for KSK members. To enable members of the public to share in this special watch, too, we also introduce the 300-piece limited edition 212 KSK – a retail version of the K212 Special Forces Command anniversary watch. The design is modelled on the anniversary edition, which is not available for retail. A commando sword surrounded by oak leaves, the KSK emblem, therefore adorns the dial of the 212 KSK as well. The rotating bezel features the 64-mil ratcheting of a German army compass, which facilitates orientation.

Germany’s commando frogman force KSM (Kommando Spezialkräfte der Marine) will now be wearing our diving watch on their wrists: the mission timer UX S Combat Swimmer (EZM 2B). This official timepiece was developed based on the technical mission requirements formulated in an international tender by the Federal Office of Bundeswehr Equipment, Information Technology and In-Service Support (BAAINBw). Out of all participating watchmaking companies, Sinn Spezialuhren best fulfils the requirements, including optimum readability under the most adverse lighting and water conditions, seawater resistance, extreme durability and operation of the rotating bezel even when wearing gloves.

On 31 July 2015, we celebrate the groundbreaking ceremony for our current headquarters in Frankfurt-Sossenheim. Lothar Schmidt demonstrates his pride in the new company building with a highly symbolic gesture: by placing his very own edition of the Frankfurt Financial District Watch 6000 in a ‘time capsule’ which is not set to be opened again for another 100 years. To make the date even more vivid for future generations, he also seals daily newspapers and magazines in the time capsule, together with a company organisational chart and a SINN catalogue. During construction, the time capsule will be buried somewhere in the middle of the new company building.

Since May 2015, Sinn Spezialuhren has been operating from its new shopping store at the Römerberg square in Frankfurt’s city. With its new sales and service rooms in the historic building “Zum Goldenen Rad”, the company is reaffirming its close affiliation with Frankfurt am Main and provides an attractive inner-city alternative to the headquarters in Frankfurt-Sossenheim.

On 24 October 2014, 57-year-old American Robert Alan Eustace parachutes from the stratosphere at a height of 41,419 metres. In doing so, he breaks the altitude record set by Felix Baumgartner two years earlier. Along for the ride is the 857 UTC TESTAF, which has been integrated into the sleeve of his special suit. Before, during and after the jump, the instrumental watch puts in a flawless performance – despite the low pressure, –77°C cold and a free-fall speed of 1,322.9 km/h, which lasts five minutes and results in Eustace breaking the sound barrier. Once his parachute opens, he glides a further ten minutes towards Earth. Eustace’s team of engineers chooses the 857 UTC TESTAF specifically for the stratosphere jump. Only afterwards do we learn about the magnificent performance of both man and watch – which is also being acknowledged by the 857 UTC TESTAF taking its rightful place alongside the suit in the National Air and Space Museum in Washington DC.

Launched in 1999, the Frankfurt Financial District Watch is celebrating its 15th anniversary. As a result, Sinn Spezialuhren is presenting Frankfurt Financial District Watch models 6052 and 6099. For the Frankfurt Financial District Watch 6052, we have developed the SZ03, which enables calendar week display.

At the request of Sinn Spezialuhren, the German Institute for Standardisation is developing the first standard for pilot watches in line with German Industry Standard DIN 8306 for diving watches. This new draft DIN 8330 is based on the technical standard for pilot watches (Technischer Standard Fliegeruhren – TESTAF), which will continue to be valid for testing and certifying pilot watches.

Aachen University of Applied Sciences and Sinn Spezialuhren present the first technical standard for pilot watches (Technischer Standard Fliegeruhren – TESTAF) on 19 July 2012 at the German headquarters of the leading helicopter and aircraft component manufacturer Airbus Helicopters (formerly Eurocopter) in Donauwörth. The development of this technical standard breaks new ground, as there was previously no suitable standard for pilot watches. TESTAF, the result of a research project at the initiative of Sinn Spezialuhren, ensures that a pilot watch meets all time measurement requirements during flight operations in accordance with visual and instrument flight regulations.

Sinn Spezialuhren presents the world’s first watches to be certified according to TESTAF standards. The development of this technical standard breaks new ground, as there was previously no suitable standard for pilot watches. TESTAF, the result of a research project at the initiative of Sinn Spezialuhren, ensures that a pilot watch meets all time measurement requirements during flight operations in accordance with visual and instrument flight regulations. Subsequently, the EZM 10 TESTAF (the first of its kind in the world), 103 Ti UTC TESTAF and 103 Ti TESTAF pass all tests successfully.

Development started in 2003. It was based on the clearly readable and well-known Lemania 5100. The SZ01 chronograph movement is designed so that any watch using it can also feature a centre-mounted, jump 60-minute stopwatch. This allows stop times to be taken even more simply, quickly and accurately. The EZM 10, a Mission Timer made from high-strength titanium, is the result of many years of development work.

A limited edition of just 500 special anniversary chronographs is presented in March 2011 to commemorate 50 years of SINN. SINN develops its own SZ05 movement for this watch. The anniversary chronograph sells out within three weeks.

SINN watches take first place for the 900 PILOT, first place for the 6100 Rose Gold and second place for the Frankfurt Financial District Watch in platinum in polling for the “Goldene Unruh” awards, making SINN Spezialuhren the most successful brand.

On the full vehicle test rig at the Fraunhofer Institute for Operational Stability and System Reliability (LBF) in Darmstadt, the 757 DIAPAL, 900 PILOT, U1000, 6000 Frankfurt Financial District Watch and the 917 GR withstand extreme impact and vibration during testing on a simulated rough road track.

Racing champions Walter Röhrl and Peter Göbel win the Costa Brava Rally for historic racing cars while wearing the 917 GR Rally Chronograph.

Together with a number of renowned partners we are supporting educational and cultural institutions in the form of universities, schools, music schools and public arts projects. MILAN is the first cultural project to receive support.

Polar explorer Arved Fuchs relies on the robustness of the U2 diving watch for his arctic expeditions.

The REGULATEUR 6100 Rose Gold takes first place in polling for the “Goldene Unruh” award.

Sinn Spezialuhren takes second place in the pilot's watch category in polling for the “Best Brand” conducted by the trade magazine “aerokurier”.

For the 6100 REGULATEUR series, SINN develops the SZ04, based on the Unitas 6498 pocket watch calibre. This is a movement with regulateur display and second stop function. The exclusivity of these watches is also underlined by the use of superior movement parts such as the Glucydur screw balance and the Triovis precision adjustment system.

The 756 and 900 models were put to a particularly demanding test of their robustness at the DEKRA Technology Center at the Lausitz Eurospeedway in Klettwitz, Germany. Normally the centre performs rigorous materials tests for the international automotive industry.

In polling for the “Goldene Unruh” award, the white gold Frankfurt Financial District Watch takes first place, and the 956 Classic takes second place.

Sinn Spezialuhren is the first company in the watch industry to have its diving watches certified by Germanischer Lloyd* of Hamburg for compliance with European standards for diving equipment. * Now DNV

For the first time, SINN uses German Submarine Steel as the case material for a diving watch.

Participants in the “most demanding adventure in the world,” the “Fulda Challenge”, wear the newly developed split-seconds chronograph 958.

Hans-Joachim Stuck wins the 24-hour-race at the Nürburgring race track wearing a 958 on his wrist.

TEGIMENT Technology is used for the first time in the 756 model. The stainless steel watch case hardened using the pioneering technology effectively protects against scratching.

DIAPAL Technology is used for the first time in the 18-carat white gold Frankfurt Financial District Watch (6000 Anniversary). The new technology features a special combination of materials that requires no lubrication, thereby ensuring long-term precision of the movement.

The 203 ARCTIC diving chronograph passes the endurance test in the Arctic Ocean on the wrist of extreme diver Mario M. Weidner with flying colours.

The introduction of the Frankfurt Financial District Watch represents a true milestone in the company's history. It is the first in a whole series of models. The words “Frankfurt am Main” appear on the dial of a SINN watch for the first time.

The company manufactures technologically sophisticated watch cases for Sinn Spezialuhren.

The 103 Ti Ar is honoured with the “Goldene Unruh” award which is rewarded for the first time.

Sinn Spezialuhren perfects Ar-Dehumidifying Technology in combination with SINN special oil 66-228 to create a Temperature Resistance Technology, with which watches remain functional between temperatures of –45 °C up to +80 °C. Equipped with the newly development technology, the chronograph 303 KRISTALL is tested at the Yukon Quest, the world's most demanding dogsled race, and passes the test with flying.

Renowned for being a maker of special timepieces, our company once again demonstrates its skill in developing two extraordinary watches: the mission timers, otherwise known as EZM 1 and EZM 2 for short. The EZM 1 is designed for missions carried out by the special unit of the Central Customs Support Group ZUZ (Zentrale Unterstützungsgruppe Zoll), while the EZM 2 is intended for the maritime unit of the Border Protection Group 9 (GSG 9). Precise, quick time measurement can mean the difference between life and death for both units. The EZMs have been reduced to an absolute minimum, ensuring optimum readability and perfect time measurement. The years that follow see an increase in the development of mission timers for specific, professional user profiles.

HYDRO Technology is introduced for the first time, in the 403 HYDRO. This technology guarantees absolute freedom from fogging, pressure resistance at every accessible diving depth and optimal readability under water at any angle.

Ar-Dehumidifying Technology is introduced for the first time, in the 203 Ti Ar diving watch. The new technology prevents the crystal from fogging up even when faced with sudden temperature changes and effectively retards the aging process of the components in the watch, thereby extending the functional life of the watch.

Despite its unusually high proportion of gold (917/1000), the 22-carat special alloy matches the material hardness of stainless steel (220 HV).

Certified engineer Lothar Schmidt acquires the company on September 1 and initiates a major strategic reorganisation to lead the company into the future and enhance its technological expertise. The company is renamed “Sinn Spezialuhren GmbH”. The company's first new model is the 244 made of titanium with Magnetic Field Protection and a freely oscillating suspended movement. With its Magnetic Field Protection feature, Sinn Spezialuhren far exceeds the DIN standard for anti-magnetic watches and minimizes magnetic disruption.

Once again, the 142 space chronograph plays a role in a space mission. On the second German Spacelab mission, the D-2, the space chronograph accompanied the crew during their 10 days in space. The watch flies 6.7 million kilometres and orbites the earth 160 times on board the NASA space shuttle Columbia.

During the Mir-92 mission, astronaut Klaus-Dietrich Flade wears a 142 S.
