Breguet Classique 5177

Breguet's Classique 5177 platinum reference 5177PT/2N/9V601 measures 38 mm across. The case stands 8.8 mm thick, with lugs finished in the fluted style typical of the collection and set 20 mm apart. A sapphire crystal covers the black Grand Feu enamel dial, read by Breguet's hollow apple hands, and a sapphire caseback shows off the self-winding calibre 777 Q beneath. That movement runs on a flat silicon balance spring and holds a 55 hour power reserve. The dial carries a central seconds display and a date aperture. An alligator leather strap closes with a platinum pin buckle. Water resistance sits at a modest 30 metres, in keeping with a dress watch rather than a tool piece.
