I have for sale my (I am the original owner) Sinn 103 STTY Classic Pilot in mint condition and good working order. This watch is a 3 register Val. 7750 chrongraph, 200m WR, domed acrylic crystal (like the Omega Speedmaster), saphire exhibition back, on a leather band with Sinn buckle. This is the model without the bezel, which in all respects resembles the IWC Flieger chronograph. As such, it is a style that allows for dress and sport wear. This is a very unique model not often seen. Sorry, I don't have a digital camera, so no scans available. References available upon request.
Price: $840 plus S&H.
