Breguet Classique Répétition Minutes 7637

Breguet's Classique Répétition Minutes 7637, reference 7637BB/12/9ZU, has a 42 mm white gold case. The case measures 12.3 mm thick, with lugs set 22 mm apart, and a sapphire crystal covers the guilloché silver dial. The manual-winding calibre 567.2 drives the watch and offers 40 hours of power reserve. A minute repeater strikes the hours, quarters and minutes on demand through a discreet lever near the case band, and small seconds sit apart from the main dial. Given the display back's sapphire caseback, the finishing on the movement remains visible from behind. The piece is fitted to an alligator leather strap with a white gold folding clasp. Breguet does not rate this model for water resistance.
