Sinn Vintage Chronograph 903

Wait, that's not a Breitling? Watch history lesson time: When Breitling fell on hard times during the Quartz crisis, it sold the rights to its original Navitimer 806 and 809 references to Sinn in Germany, as they too wanted to produce a watch with a logarithmic scale, slide rule and chronograph. And with Breitling in need of funds, a deal was struck and hence the Sinn 903 was born.

This particular example dates to the 80's, and presents in amazing vintage condition. The 40mm steel case is very sharp, thick and with excellent finishes. Has some small dings, nicks and scratches as can be seen in the images. The dial is original glossy tritium, as are the hands. Please see images for full condition details.

Powering it is a Valjoux 7740 manual wind. Service history is unknown, but it winds very smoothly, chrono operates as it should, and it's keeping COSC time.

Comes with Watch Vault cleaning cloth and Watch Vault travel pod.
