Sinn 203 Diving Watch Anniversary Limited edition

This limited edition diving watch was launched in 2006 to celebrate the 45th anniversary of the company. The years 1961-2006 and the dial underscore the value of the diving watch. It is tastefully electroplated in a special charcoal grey colour – a complex but rewarding process, as it produces a deep, silky matte gleam and outstanding colour fastness.  The robust case is made of titanium. The appeal of this metal lies in its light weight and low thermal conductivity, which make it comfortable to wear.

Moreover, it is non-allergenic. It is also an extremely precise timepiece thanks to the Valjoux 7750 movement with automatic winding. Functional robustness und reliability are indispensable for underwater sports or professional activities and are crucial to health and life. The 203 anniversary diving watch comes in a case with a brown Russian leather strap, strap changing tool, spring bars and an operating manual.
