This reference was a foundational model within the Clifton collection, which debuted at SIHH 2013 to translate the brand’s archival "golden fifties" designs into a modern context. It utilizes the classic complete calendar layout, indicating the day and month in twin apertures, the moonphase at six o'clock, and the date via a central pointer hand. The complications are driven by the reliable Swiss automatic Dubois-Dépraz module, which is based on an ETA automatic caliber and visible through a sapphire caseback. By presenting this traditional horological display in a contemporary 43mm steel case, the M0A10057 codified the collection's strategy of blending vintage aesthetics with accessible, modern watchmaking.
Cemented by the 1918 partnership between William Baume and Paul Mercier. Their vision of blending technical expertise with modern design earned the firm the prestigious Poinçon de Genève in 1919, a mark of exceptional quality. The brand’s legacy is defined by its expertise in shaped timepieces, exemplified by the Art Deco-inspired Hampton, and its early entry into the luxury steel sports watch category with the launch of the dodecagonal Riviera in 1973.
As a member of the Richemont Group today, Baume and Mercier maintains its focus on delivering value through the development of its proprietary Baumatic calibre. This high-performance movement, featured in the classic Clifton collection, offers chronometer-level precision and advanced anti-magnetism. Consequently, the manufacture is correctly positioned as a formidable entry point for new collectors due to their wide range of mechanical models.
