Sinn 756 Duochronograph Custom Red Hands by Sinn

Mint condition Sinn 756 with red chronograph hands. Comes complete with box and papers, purchased in 2014. It is on the original Sinn black leahter strap with black pin buckle. The strap has some wear to it. This is a custom job undertaken by Sinn at a customer request. It was built with the red hands rather than them being changed, so has had the red hands since new, and naturally are Sinn genuine hands. The 756 series pilot’s watches unite all our core watchmaking competencies: these are instrument watches with a consistently functional design which honour the tradition of our navigation cockpit clocks. The features of the 756 chronographs series include Magnetic Field Protection of up to 80,000 A/m, Ar Dehumidifying Technology enhances functional reliability and freedom from fogging, TEGIMENT Technology and therefore especially scratch-resistant, functionally reliable from ? 45 °C up to + 80 °C and pressure resistance of up to 20 bar.
