Sinn Watch 358 Sa Pilot DS Silicone Black 358.065 Silicone Black.  Following on from the success of the Sinn 356, the stunning Sinn 358 Sa Pilot DS watch brings the famous pilots chronograph to life in a larger sized case and with a unique textured dial. At its centre, the wearer can enjoy an exciting play of colours as the base material of the dial reflects different nuances of light. This is the result of decorative grinding, a machining process that can never be replicated making each Sinn 358 Sa Pilot DS watch completely individual to its wearer. Despite its mesmerising finish, the dial does not take away from the watch’s clear readability with large Arabic numerals and luminous hands marking the centre. Ensuring it remains a robust and reliable pilots watch, the Sinn 358 Sa Pilot DS is engineered from satinized stainless steel and features the brand’s legendary Ar-Dehumidifying Technology which enhances functional reliability and freedom from fogging. Measuring to 42mm in diameter, the case also delivers domed sapphire crystal glass treated with anti-reflective coating, a screw in crown and a screw fastened exhibition case back guaranteeing a water resistant rating of 100 metres. Through the case back, you can admire the SW500 automatic winding movement which alongside 25 bearing jewels and a beautifully decorated ribbed rotor, provides central hands for hours, minutes and chronograph seconds, three subsidiary counters for small seconds, 12 hours and 30 minutes and a day and date window at 3 o’clock.
