The Baume & Mercier Chronograph Calendar 86.102.099 is a vintage Swiss-made calendar chronograph from Baume & Mercier, typically produced in the 1980s–1990s. It features a classic round case (often in yellow gold), a manual-winding movement with chronograph and calendar functions, and a clean dial that combines sub-dials with date and moonphase indications for both timekeeping and timing. The watch embodies the brand’s understated blend of elegant design and practical complications from that era.
