Baume & Mercier Classima Silvery white, Opaline Dial 40mm Men M0A10874

Embodying classical Swiss mechanical purism, understated Genevan refinement, and ergonomic dress proportions, the Baume & Mercier Classima Automatic 40mm M0A10874 represents a quintessential gentleman's dress watch crafted in the historic watchmaking tradition of the Swiss Jura. Sculpted in a 40.00 mm surgical-grade 316L stainless steel round case measuring an ultra-slender 8.90 mm in profile with a 21 mm lug width, this luxury timepiece pairs mirror-polished surfaces with slender curved lugs engineered to sit close to the wrist and slide beneath tailored French shirt cuffs. The dial features a pristine silvery-white opaline finish, framed by crisp black transfer Roman numerals, minimalist baton hour indices, and slender ruthenium-coated leaf (feuille) hands. A beveled date aperture at 3 o'clock preserves the dial's balanced symmetry beneath a scratch-resistant sapphire crystal. Driven by a Swiss Made Sellita Calibre SW200 self-winding automatic movement operating at 28,800 vibrations per hour (4 Hz) across 26 jewels with a 38-hour power reserve, it features a full solid screwed case back optimized for personal engraving. Mounted on an interchangeable black alligator-patterned calfskin leather strap featuring tool-free quick-release spring bars and a polished steel ardillon pin buckle, it is pressure-tested for 50 metres (5 bar / 5 ATM) of water resistance and backed by Baume & Mercier’s official 2-year international manufacturer warranty.

Design & Craftsmanship

Swiss Jura Mechanical Heritage & The 8.90mm Steel Architecture

Established in 1830 in Les Bois, Switzerland, Baume & Mercier has long championed the philosophy: "Accept only perfection, only manufacture watches of the highest quality." The Classima collection translates this ethos into an everyday dress watch. Sized at 40.00 mm in diameter, reference M0A10874 achieves an ultra-slender 8.90 mm case profile for an automatic mechanical movement. Forged from surgical-grade 316L stainless steel, the case is mirror-polished across the stepped bezel, case flanks, and curved lugs. The full case back is secured by screws to ensure structural integrity and provides a canvas for personal commemorative engravings. The polished steel winding crown is embossed with the Greek letter Phi (Φ)—the horological emblem of the Golden Ratio and divine harmony.
