Breguet Classique Phase de Lune 7787

Breguet's Classique Phase de Lune 7787BB/29/9V6 is a 39 mm case in white gold. The case measures 10.3 mm thick, with lugs set 20 mm apart, and carries a sapphire crystal over a white "Grand Feu" enamel dial. Inside is the self-winding calibre 591 DRL, offering 38 hours of power reserve. The dial shows central hours, minutes and seconds, with a moon phase at 12 o'clock and a power reserve display at 3 o'clock read off a long, slender hand. A sapphire case back exposes the movement's finishing. The strap is alligator leather, closed with a white gold folding clasp. Rated to 30 metres, the case keeps its water resistance modest, in keeping with a dress watch of this kind.
