Breitling Chronomat A10380591A1A1

The case measures 36mm across and 10.01mm thick. Case material: Stainless steel. 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 10 (non-in-house; ETA 2892-A2 or Sellita SW300-1 base), COSC-certified. Power reserve is 42 hours.

It is rated to 100 meters, about 328 feet. That is enough for swimming and snorkeling, but not for scuba diving. 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.

Breitling produced this reference from 2020 to the present day. Production years matter when you are valuing one, because dial, bezel and bracelet details often changed inside a single reference run.

Chars 2-3 = movement family (10-49 mechanical, 50+ quartz; in-house calibers carry a leading B, e.g. B01); char 4 = COSC certification (0 = non-COSC, 3 = COSC); chars 5-6 = model type; chars 7-8 = case/bezel finish; trailing group = dial and strap/bracelet. Applied here: A / 10 / 3 / 80 = steel case, Caliber 10 family, COSC, model 80 (Chronomat Automatic 36); finish 59 = gem-set (Breitling's own page title for this reference reads "Chronomat Automatic 36 Stainless steel (gem-set) - White"); dial A1 = white; bracelet A1 = steel Rouleaux. LONG form, so dial and bracelet are determined. 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.
