Breguet Classique 5177

The case measures 38mm across and 8.8mm thick, with a 20mm lug width. Case material: 18k gold (white or rose) or platinum, fluted coin-edge case band. 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, Breguet Cal. 777Q, in-house. Power reserve is 55 hours. It beats at 28,800 vph. The movement uses 26 jewels.

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.

Breguet produced this reference from 2008 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.

5177 = Classique automatic family; metal/dial/strap follow as suffix (e.g. 5177BB = white gold, 5177BR = rose gold). 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.

Classique 5177 (automatic, enamel or guilloché dial). Collector nicknames are not official Breguet names, but they are what people actually search for and what they are called across a showroom.
