Breitling Super Chronomat AB0136251B1S1

The case measures 44mm across and 14.45mm 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 Manufacture Caliber 01 (in-house), COSC-certified chronometer. The caliber is the B01. Power reserve is 70 hours.

It is rated to 200 meters, about 656 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.

Current-format reference. A = stainless steel case; B01 = Breitling's in-house Manufacture Caliber 01, the B prefix marks an in-house movement, a bare two-digit caliber number would mean a third-party base. The trailing group fixes the dial and the strap: the same watch is catalogued as AB0136251B1S1 (black dial, rubber) alongside AB0136161C1S1 (blue dial, rubber), UB0136251B1S1 (steel and gold) and PB0136251C1S1. 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.
