Breguet's Classique Phase de Lune 9087, reference 9087BR/29/964, has a 30 mm rose gold case. The case measures 9.8 mm thick, with lugs set 16 mm apart. A sapphire crystal covers the white dial, and Breguet fits a sapphire caseback that reveals the movement. Inside is the self-winding calibre 537L, offering 45 hours of power reserve.
