Breguet Classique Calendrier 7337

Breguet's Classique Calendrier 7337, reference 7337BA/1E/9V6, comes in an 18-carat yellow gold case measuring 39 mm across and 10 mm thick. The self-winding calibre 502.3 QSE1 runs at the centre of the case and offers 45 hours of power reserve. A sapphire crystal covers the silver dial, which is hand-guilloché on a rose engine, and a sapphire caseback on the reverse shows the movement's finishing. Central seconds, date and moon phase share the dial, all read off against the hand-engraved guilloché pattern. The date appears through an aperture rather than a printed track, keeping the layout uncluttered. An alligator leather strap closes with a folding clasp in yellow gold. The case is rated to 30 metres of water resistance.
