Breguet Classique Quantième Perpétuel 5327

Breguet's Classique Quantième Perpétuel 5327, reference 5327BB/1E/9V6, has a 39 mm case in white gold. The case measures 9.1 mm thick, with lugs set 20 mm apart. A self-winding movement, calibre 502 DRP1, drives the watch and offers 45 hours of power reserve. The silver dial is hand-guilloché on a rose engine, and its symmetry places the moon phase opposite the power reserve display, with a perpetual calendar spread across the date, day and leap-year indications. A sapphire crystal covers the dial, and a sapphire caseback exposes the movement's finishing. The watch is fitted to an alligator leather strap with a white gold folding clasp. Water resistance is rated to 30 metres.
