Baume & Mercier Classima Dark Green, Sans, Sunray Dial 42mm Men M0A10783

Fusing traditional Swiss haute horlogerie elegance with contemporary color aesthetics, high-complication mechanical timing, and refined executive ergonomics, the Baume & Mercier Classima Automatic Chronograph 42mm M0A10783 represents a commanding statement in modern gentleman's horology. Sculpted in a 42.00 mm surgical-grade 316L stainless steel round case measuring 13.25 mm in profile with a 21 mm lug width, this timepiece pairs mirror-polished surfaces with smooth, ergonomically curved lugs designed to sit flush against the wrist. The dial showcases a radiant sun-satin dark green face (vert foncé satiné soleil) framed by a contrasting slate flange and two tone-on-tone snailed (azuré) chronograph counters at 12 o'clock (30-minute accumulator) and 6 o'clock (12-hour totalizer), complemented by a running small seconds sub-dial at 9 o'clock. Flanked by a dual Day-Date calendar aperture at 3 o'clock, slender rhodium-plated baton indices, and polished leaf-shaped (feuille) hands beneath a scratch-resistant sapphire crystal, it is powered by a Swiss Made self-winding mechanical automatic chronograph movement operating at 28,800 vibrations per hour (4 Hz) with a 48-hour power reserve. Mounted on an interchangeable brown-gray suede calfskin leather strap featuring tool-free quick-release spring bars and a stainless steel triple-folding deployant clasp with security pushers, 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 42mm Polished Steel Chassis

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 timeless round dress watches. In reference M0A10783, Baume & Mercier combines traditional proportions with chronograph sport-luxury architecture. Sized at 42.00 mm in diameter with a 13.25 mm case height, the round chassis is forged from surgical-grade 316L stainless steel and finished in a mirror polish across the stepped bezel, case flanks, and curved lugs. The fluted push-pull winding crown is flanked by classic piston-style chronograph pushers at 2 and 4 o'clock and finished with the Greek letter Phi (Φ)—the emblem of the Golden Ratio and divine harmony. On the reverse side, an exhibition sapphire crystal case back reveals the decorated mechanical movement.
