Classic design language with refined details: The 104 Classic 12 stands for a distinctive profile combined with technically superior features. A timepiece that skillfully merges the functionality of an instrument watch with the craftsmanship of traditional horology. Its unmistakable appearance bears the hallmark of Sinn Spezialuhren: timeless and full of character.
At its core is the small seconds display, realized for the first time in this model series. Elegantly showcased with a chamois-coloured small second, tastefully accentuated by fine grooves and polished chamfers. Sunburst finishing, rhodium-plated appliqués and hands, as well as the finely tuned colour palette, carry the design language through with coherence – harmoniously balanced down to the smallest detail.
Another exceptional feature is the pilot’s bezel with hour ratcheting, which includes a high-quality ceramic inlay. This material also makes its debut in this model series and is characterized by exceptional hardness and, consequently, outstanding scratch resistance. The 12-hour scale on the bezel allows the indication of a second time zone and is securely captive within the case, true to the proven SINN technology standards.
The 104 Classic 12 is water-resistant and pressure-resistant to 20 bar, and also low pressure resistant. Altogether, a timepiece with true character – for watch enthusiasts who appreciate engineering excellence, have a refined sense of style, and a passion for mechanical precision.
