This is a Tavannes (Trusty) trade watch. It's likely a 15-jewel watch, and the case, dial, and movement are all in very good condition. The fish-scale pattern unique to trade watches on the back of the case has sharp edges. The dial has no hairlines or "clam shell" marks, and the movement has some slight scuffs and rust, but almost no scratches, and is in quite good condition. Above all, the hands and dial are beautiful. It's a triple-signed watch, with the brand name on the dial, movement, and case. Currently, it's unstable, starting up at times and then stopping after a while. The mainspring is fully wound. As mentioned, the condition is good, but there are age-related scratches and scuffs.
