Breguet Classique Répétition Minutes 7637

Breguet's Classique Répétition Minutes 7637, reference 7637ER/10/9ZU, is a 42 mm rose gold case with a minute repeater. The case measures 12.3 mm thick and carries a discreet lever between 8 and 10 o'clock to activate the chime. Inside is the manual-winding calibre 567.2, giving 40 hours of power reserve, and the movement is visible through a sapphire caseback. The gold dial is guilloché, with an off-centre small seconds display set into its architecture. A sapphire crystal covers the dial, which is fitted to an alligator leather strap on a rose gold folding clasp. Beyond the striking mechanism, the piece is built for handling and precision rather than depth, and Breguet notes it is not waterproof.
