Founded by Mr. Sinn a few decades ago, who was a WW2 pilot. His idea of the perfect readable cockpit watch marked the path of the company for quite a long time. Nowadays they have perfected this concept, adding high end materials technology like tegmentation of sophisticated steels (German submarine steel f.e.), and filling argon into the watch cases for complete isolation from atmospheric effects. No house calibers yet. Famous are their special forces watches of the EZM series („Einsatzzeitmesser“), and their very classical pilot‘s watches. Excellent finish, and a good price performance ratio. Their main showroom and HQ is situated close to Frankfurt/Main. A second showroom you find amidst the old center of Frankfurt, close to the „Roemer“.
