Marrying historic Swiss mechanical watchmaking traditions with classical aesthetic symmetry, intricate guilloché craftsmanship, and rich monochrome elegance, the Baume & Mercier Classima Automatic 40mm M0A10879 represents a benchmark in modern executive gentlemen's horology. Sculpted in a 40.00 mm surgical-grade 316L stainless steel round case measuring an ultra-slender 9.00 mm in profile with a 21 mm lug width, this luxury dress timepiece pairs mirror-polished surfaces with slender curved lugs designed to sit flush against the wrist and slide beneath tailored French shirt cuffs. The dial features a radiant sun-satin deep blue finish (finition soleil) enriched by an intricate central barleycorn (grain d'orge) guilloché engraving that scatters ambient light in dynamic azure, cobalt, and midnight tones. Framed by rhodium-plated Roman numerals, faceted linear baton indices, and sculpted leaf (feuille) hands, a date aperture at 3 o'clock completes the dial beneath a scratch-resistant sapphire crystal. Through the exhibition sapphire crystal case back, the Swiss Made Sellita Calibre SW200 automatic self-winding movement is visible, operating at 28,800 vibrations per hour (4 Hz) across 26 jewels with a 38-hour power reserve. Fitted with an interchangeable dark blue alligator-patterned calfskin leather strap featuring tool-free quick-release spring bars and a polished steel pin buckle, it is pressure-tested to 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 40mm 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 M0A10879 achieves a slim 9.00 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. On the reverse side, an exhibition sapphire crystal case back reveals the rhodium-plated oscillating weight and running gear train. The winding crown is embossed with the Greek letter Phi (Φ)—the horological emblem of the Golden Ratio and divine harmony.
