Baume & Mercier Classima Silvery white, Opaline Dial 40mm Men M0A10884

Epitomizing Swiss haute horlogerie discretion, classical purism, and ultra-slender ergonomics, the Baume & Mercier Classima 40mm M0A10884 is 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 with an ultra-thin 5.95 mm profile, this timepiece combines mirror-polished surfaces with slender, curved lugs engineered to slide beneath tailored French shirt cuffs. The dial features a silvery-white opaline finish framed by a clean periphery, punctuated by crisp black transfer Roman numerals, minimalist baton hour indices, and slender ruthenium-finished leaf (feuille) hands. A beveled date aperture at 3 o'clock preserves the dial's symmetry beneath a scratch-resistant sapphire crystal. Driven by a Swiss Made ETA Calibre F06.115 quartz movement with an extended 4-year (48-month) battery autonomy and End-of-Life (EOL) indicator, it is mounted on a black calfskin leather strap featuring a tool-free quick-release interchangeability system and an ardillon pin buckle. Pressure-tested for 50 metres (5 bar / 5 ATM) of water resistance, it is protected by Baume & Mercier’s official 2-year international manufacturer warranty.

Design & Craftsmanship

Swiss Jura Dress Heritage & The 5.95mm Ultra-Thin 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 M0A10884 features an ultra-thin 5.95 mm case profile that sits close against the wrist. Forged from surgical-grade 316L stainless steel, the case is mirror-polished across the bezel, case flanks, and curved lugs. The full case back is secured by screws to maintain structural integrity, while the polished steel winding crown is finished with the Greek letter Phi (Φ)—the horological emblem of the Golden Ratio and divine harmony.
