Sinn Spezialuhren stands for highly functional mechanical watches. Our pilot watches, diving watches, chronographs and Mission Timer (Einsatzzeitmesser / EZM) are designed to impress not only pilots, divers, and the German federal police special force GSG 9 (Grenzschutzgruppe 9). SINN watches continuously prove their toughness, durability, high quality and precision in both everyday and extreme situations. These characteristics are due in no small part to the incorporation of our special technologies including DIAPAL, Ar-Dehumidifying Technology, HYDRO and TEGIMENT . When Sinn Spezialuhren develops a new watch, its form is always dictated by the required function.
