Breitling Superocean N173761A1C1S1

The case measures 44mm across and 12.62mm thick. Case material: Bronze. Case size alone is a poor guide to how a watch wears; lug-to-lug length and how the bracelet drops off the case matter more, which is why we suggest trying one on before you commit.

Automatic, Breitling Caliber 17. Power reserve is 38 hours.

It is rated to 300 meters, about 984 feet. That is a diving rating: it is built for scuba use, not just for getting wet. One caution that applies to every watch on this page: a water resistance figure describes a new watch with fresh gaskets. On a piece that is years past its last service, treat the rating as unknown until it has been pressure tested.

Only partially decodable from documented sources. Positions 2-3 (here 17 = Breitling Caliber 17) and a COSC flag in position 4 (3 = COSC-certified), and the dial code in the trailing letter pair (C1 = blue in their dial tables), with the final pair identifying the strap. I did NOT find a documented material meaning for a leading N in the current scheme: the published tables predate it and list N = carbon, while Breitling's own spec sheet for this reference states a bronze case. I am not asserting a rule I could not source. Breitling does not publish this scheme. It is compiled from collector documentation and reads as a reliable guide rather than a manufacturer specification.. Reading the reference is the fastest way to confirm that a watch is what the seller says it is, before you get anywhere near the movement.
