Breitling Navitimer AB012721/BD09

The case measures 46mm across. 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. The caliber is the B01. Power reserve is 70 hours.

It is rated to 30 meters, about 98 feet. That covers rain and hand washing. It is not rated for swimming. 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.

B01 in the caliber position denotes an in-house Breitling Manufacture caliber (Caliber 01) rather than an ETA or Valjoux base; the group after the slash (BD09) is the DIAL code. In this older format the bracelet or strap is a further code appended after the dial code - dealers list this watch as AB012721/BD09-441X (steel Navitimer bracelet), -754P (leather), -258S, etc. - so the bracelet is NOT determined by the reference as given. 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.
