Baume & Mercier Clifton Baumatic M0A10468 Automatic 40 mm

The Clifton Baumatic's 120-hour power reserve is worth noting on its own terms: five days of running time from a single wind, driven by the calibre BM13-1975A and its 21 jewels. A steel-blue dial fills the case, sized between 30mm and 40mm, with date display and water resistance to 5 ATM handling the everyday. The warranty extends to eight years rather than the usual two, a detail that speaks to how the Baumatic movement is built. It suits business meetings and interviews through to dinner.
