The Classima's automatic line runs on the calibre BM 11200, a self-winding movement built around 26 jewels and a power reserve of 38 hours, enough to carry the watch through a weekend off the wrist without needing to be reset. A silver dial sits inside a steel case between 30mm and 40mm, finished with date display and water resistance to 5 ATM. The Baume & Mercier Classima M0A10215 Automatic 40 mm is built in Switzerland and carries two years of international warranty, suited equally to an interview, a business meeting, or dinner afterward.
