A perpetual calendar in a steel sports watch, made in 50 pieces. This Baume & Mercier Riviera Baumatic Perpetual Calendar Ref. M0A10786 sets the complication inside the Riviera's twelve-sided 40mm case, with exposed screws, alternating brushed and polished surfaces and an integrated three-row stainless-steel bracelet.

The vertically brushed grey dial carries gold-tone Dauphine hands and markers, snailed recessed counters for day, date and month, and a moonphase at 6 o'clock. The perpetual calendar accounts for month lengths and leap years when set and kept running. Inside is the automatic Baumatic manufacture calibre with 120 hours of power reserve, five days of autonomy that helps keep the calendar set between wears.

Presented in mint condition as a 2025 full set with the original box and papers, including the international warranty card dated September 30, 2025. Factory warranty coverage runs to September 30, 2027, extendable to September 30, 2033 if the manufacturer's warranty extension was activated. Extension status has not been confirmed.
