Harmonizing historic Swiss Jura watchmaking discretion with classical aesthetic purism, warm precious-metal accents, and ultra-slender ergonomics, the Baume & Mercier Classima 40mm M0A10857 represents an aristocratic gentleman's dress watch. Sculpted in a 40.00 mm surgical-grade 316L stainless steel round case treated with an opulent 4N rose-yellow gold PVD finish, this model features an ultra-thin 6.05 mm profile and a 21 mm lug width. The case combines mirror-polished surfaces with slender, ergonomically curved lugs designed to sit flush against the wrist and slide smoothly beneath tailored French cuffs. The dial showcases a radiant silvery opaline sun-satin face enriched by an intricate central barleycorn (grain d'orge) guilloché engraving that scatters ambient light in subtle Champagne and pearl reflections. Accented by applied 4N gold-tone Roman numerals, faceted linear baton hour indices, matching 4N gold-tone leaf (feuille) hands, and a balanced date aperture at 3 o'clock beneath a scratch-resistant sapphire crystal, it is powered by a Swiss Made ETA Calibre F06.115 quartz movement offering an extended 4-year (48-month) battery autonomy and End-of-Life (EOL) indicator. Mounted on an interchangeable dark brown alligator-patterned calfskin leather strap featuring tool-free quick-release spring bars and an 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 Dress Heritage & The 40mm 4N Gold PVD 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 M0A10857 features an ultra-thin 6.05 mm case profile that sits close against the wrist. Forged from surgical-grade 316L stainless steel, the case is finished with a warm 4N gold-tone PVD coating that alternates between mirror-polished stepped bezels and smooth case flanks. The full solid steel case back is secured to maintain structural integrity and offers space for personal custom engravings, while the fluted winding crown is finished with the Greek letter Phi (Φ)—the horological emblem of the Golden Ratio and divine harmony.
