Breguet Classique Calendrier 7337

Breguet's Classique Calendrier 7337BB/1E/9V6 is a 39 mm white gold watch with a case measuring 10 mm thick. The silver dial is hand-guilloché on a rose engine and carries a moon phase display along with the date, both read off apertures set into the layout, plus a central seconds hand. A sapphire crystal covers the dial and a sapphire caseback lets the self-winding calibre 502.3 QSE1 show through. That movement runs at 3 Hz with 45 hours of power reserve and drives a Breguet balance wheel with a flat silicon balance spring. The watch is fitted to an alligator leather strap closed with a white gold folding clasp. Water resistance stays modest at 30 metres, in keeping with its dress-watch nature.
