Sinn Watch 206 St Ar Fine Link Bracelet 206.010 Fine Link Bracelet. Epitomizing a classic diving chronograph, this remarkable Sinn 206 St Ar watch is inspired by two historic Sinn watches from the past, the 203 St and the 203 Ti Ar, two remarkable instruments that were the first to use Sinn’s famous Ar-Dehumidifying Technology in 1995. This impressive technology continues to be used within this Sinn 206 St Ar watch to guarantee functional reliability in temperatures ranging from -45 to +80 Celsius. Remaining as true to the original 203 model as possible, this striking Sinn 206 St Ar watch is presented with a breathtaking electroplated black dial decorated with hour, minute and chronograph seconds hands coated in luminescent colour. The dial is also equipped with a day and date window and three subsidiary dials for continuous seconds, 30 minutes counter and 12 hours counter, all powered by the remarkable Valjoux 7750 self winding movement. In typical Sinn fashion, this Sinn 206 watch is fitted with an incredible range of innovations including a 43mm captive bezel with minute ratcheting,  Ar-Dehumidifying Technology which enhances functional reliability and freedom from fogging and push-pieces with D3-System. For one final touch of sophistication, this Sinn 206 St Ar watch is complimented by a luxurious fine link stainless steel bracelet and folding clasp.
