A series of pilot watches, diving watches, chronographs, Mission Timers and more, all created for the explorers and risk-takers. Sinn watches are highly functional and created to fulfill the intended function.

Sinn Spezialuhren stands for highly functional mechanical watches and since its founding in 1961, the company has focused on high-quality, mechanical watches.  Our pilot watches, diving watches, chronographs and Mission Timers continuously prove their toughness, durability, high quality and precision in both everyday and extreme situations. When Sinn Spezialuhren develops a new watch, its form is always dictated by the required function. These characteristics are due in no small part to the incorporation of our special technologies including Ar-Dehumidifying Technology, DIAPAL, HYDRO and TEGIMENT and more.




The long-term accuracy of a watch movement crucially depends on the lubrication of its moving parts – this is particularly true at extreme temperatures. We use a special oil (66-228) developed by SINN to ensure reliable function under even the most extreme conditions. With its outstanding properties, it provides lubrication that is highly resistant to aging at temperatures between –45°C and +80°C. These innovations are currently available exclusively in our watches. And there’s no limit on innovation. The best is yet to come.
