Breguet - Calendrier perpétuel

This perpetual calendar watch has a 750 (18K) yellow gold case with fluted caseband, rounded horns and screw-in lugs. The hand-engraved silvered gold dial, which is numbered and bears the Breguet signature, features blued steel Breguet hands for the time, a serpentine retrograde hand for the date, three windows for the day of the week, month and leap year and, in a semi-circular aperture, the phases and age of the moon. Twin-barrelled automatic movement. Engine-turned 22K gold rotor. Sapphire caseback.
