For sale today is my Sinn 103 St Ac. It has a custom brushed case and Sinn 103 TESTAF handset. All the custom work was done by my watchmaker, who also gave the movement a minor service while he had it out of the case. The watch comes with its original boxes, papers, warranty card, etc. The original Sinn strap is in perfect shape, and the watch comes on a Horween shell cordovan strap in Color No. 8. This 103 runs perfectly with no issues. The chronograph action starts, stops, and resets perfectly. This is a no-issues 103 with a unique and appealing customization. $1300 USD shipped and PayPaled in the USA. No returns unless the watch arrives not as described. Lots of references here and elsewhere so buy from me with confidence. Thanks, Myron
