Official Authorised Agent
Sinn's 900 range of instrument chronographs is the largest one that the company has designed – the case diameter is 44 millimetres. The 900 Pilot watch is equipped with Valjoux 7750 automatic calibre that performs 28 800 vibrations per hour and has 26 bearing jewels. The case is hardened through the use of Sinn's Tegiment technology. A dehumidifying capsule protects the mechanism and keeps the dial from fogging. The watch is also resilient to magnetic influences. Other useful functionalities include a second time zone, scales for conversions from American to European units and vice versa, a date window at 3 o'clock, appliqués attached by hand, luminous dial elements, nickel-free case back and scratch-resistant sapphire crystal glass with anti-reflective coating.
