Breguet Classique Phase de Lune 7137

Breguet's Classique Phase de Lune 7137, reference 7137BR/15/9VU, is a rose gold dress watch measuring 39 mm across. The case stands 8.7 mm thick, with lugs set 20 mm apart, and the silvery dial sits under a sapphire crystal. Three distinct guilloché patterns, done by hand, separate the dial's indications and give it a texture that shifts with the light. The self-winding calibre 502.3 DR1 drives the watch, with 46 hours of power reserve, and a sapphire caseback shows the movement's finishing. Beyond the date, the dial carries a moon phase display and a power reserve indicator. An alligator strap closes with a rose gold folding clasp, and the case is rated to 30 metres.
