Baume & Mercier Clifton watches

The Baume & Mercier Clifton is the brand's collection of round, classically styled watches, running from time-only automatics to calendars, chronographs and a sports line with a diving bezel. Baume & Mercier presented it at SIHH 2013 as a modern take on a 1950s Baume & Mercier watch.

Launch coverage described a double-bevelled case in polished and satin-finished steel or 18k red gold under a sapphire crystal. The first references included two 41 mm automatics, 10052 and 10053, and the 42 mm red gold ref. 10060, with a manual-wind La Joux-Perret 7381 movement. In 2018 the Clifton Baumatic brought the automatic calibre BM12-1975A, with a five-day (120-hour) power reserve and a silicon hairspring, pallet fork and escape wheel. It was developed within the Richemont group and derives from Cartier's 1847 MC movement, and some Baumatic references are COSC-certified chronometers.

The Clifton Automatic is the 41 mm, 11.5 mm-thick everyday model. The Baumatic is slimmer at 40 mm and 10.3 to 11.1 mm, with a 39 mm red gold version; references with COSC in the name are the chronometers. The complications sit in 43 mm cases: the Chronograph, Complete Calendar, Chronograph Complete Calendar and GMT. The red gold Clifton 1830 models run from the hand-wound 10060 to a Perpetual Calendar and the 45 mm Eight Day Power Reserve, limited to 185 pieces. The Clifton Club is the sports line, 42 mm with a rotating diving bezel, joined by 44 mm Shelby Cobra editions such as the CSX2299 of 196 pieces. At the small end, the Clifton Quartz (10175) measures 30 mm.
