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.
A new era begins
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 first gold watch made by SINN
Despite its unusually high proportion of gold (917/1000), the 22-carat special alloy matches the material hardness of stainless steel (220 HV).
Development of Ar-Dehumidifying Technology 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.
Development of HYDRO Technology 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.
Sinn Spezialuhren introduces the EZM1 and EZM2 mission timers
Known as a maker of special timepieces, SINN once again proves its competence with the development of two extraordinary mission timers known as the EZM1 and EZM2. These timepieces are designed for use in missions by special police forces and the GSG 9 (Border Protection Group 9 of Federal Police), where precise timing can mean the difference between life and death. The mission timers focus on the absolute essentials: optimal readability and perfect measurement of time. In the following years, additional mission timers were developed for special, professional user profiles.
– 45°C up to +80°C
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 colours.

Presentation of the Frankfurt Financial District Watch
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 face of a SINN watch for the first time.
Development of DIAPAL Technology DIAPAL Technology is used for the first time in the 18-carat white gold Frankfurt Financial District Watch (6000 Jubilee). The new technology features a special combination of materials that requires no lubrication, thereby ensuring long-term precision of the movement.
Development of TEGIMENT Technology 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.
Limited-edition chronograph 958 with a stay-set indicator

“Goldene Unruh” award for the white gold Frankfurt Financial District Watch
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 watches withstand crash test
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.
Development of the SZ04 hand-wound movement
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.
Support for the arts
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.
SINN watches on rough-road simulation track
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 Finance District Watch and the 917 GR withstand extreme impact and vibration during testing on a simulated rough road track.
Most successful brand in polling for the “Goldene Unruh”
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.
The central stop minute hand – the SZ01
Development started in 2003. It was based on the clearly readable and well-known Lemania 5100. The SZ01chronograph 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 on the SZ01.
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.
World premiere: the first TESTAF-certified watches
Sinn Spezialuhren presents the first watches certified according to TESTAF standards in the world. In the first series of trials, three SINN models meet the requirements. Various adjustments need to be made for these three watches to meet all the testing criteria. Subsequently, the EZM 10 TESTAF, 103 Ti UTCTESTAF and 103 Ti TESTAF passed all tests successfully. In addition to the certificate, this is proven by the TESTAF quality seal on the dial.
TESTAF: the basis for a new standard in pilot watches
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.
15 years of Frankfurt Financial District Watches
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.
857 UTC: record jump from the stratosphere
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, 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 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 taking its rightful place alongside the suit in the National Air and Space Museum in Washington DC.
Opening of the SINN Römerberg branch
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 offering an attractive inner-city alternative to its headquarters in Frankfurt-Rödelheim, which continues to produce and sell SINN watches.
Groundbreaking ceremony at the new company headquarters in Frankfurt Sossenheim
As of early 2017, our new address will be Wilhelm-Fay-Strasse 21, 65936 Frankfurt am Main. Although staying in Frankfurt, the company will be moving into new headquarters in the district of Sossenheim. The groundbreaking ceremony is therefore held on 31 July 2015. 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.
New DIN 8330 for pilot watches
For the first time in decades, the German Institute for Standardisation (DIN) publishes a new German watch standard: DIN 8330 for 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 for pilot watches 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. It also serves to expand the range of watches that are able to adhere to it in line with TESTAF – for example, by incorporating quartz watches.
Sinn Spezialuhren celebrates its 55th anniversary
Three 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, which is limited to 55 pieces.
Model 6200 Meisterbund I
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, which is limited to 55 pieces, SUG is responsible for building and manufacturing the case made of 18-carat rose 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.
New company headquarters in Frankfurt Sossenheim
The move is scheduled for early 2017. Occupying an area of approximately 7,000 square metres, the new property is a symbol of our company’s prosperity. The company will thus swap the 1,950 square metres currently at its disposal for 4,650 square metres, enabling the expansion of assembly and production areas. This will lead to an increased level of vertical integration. As our watches will also be sold directly in Sossenheim, customers can look forward to larger showrooms and continued personal customer service.
