Baume & Mercier Riviera Yellow, Sans Dial 39mm Men M0A10822

Fusing the legendary 1973 dodecagonal luxury sports silhouette with state-of-the-art Swiss manufacture mechanics, radiant vintage warmth, and tailored modern proportions, the Baume & Mercier Riviera Baumatic 39mm M0A10822 represents an exceptional expression of contemporary high horology. Sculpted in a 39.00 mm surgical-grade 316L stainless steel case measuring 10.21 mm in profile with an integrated lug architecture, this timepiece showcases the signature Riviera 12-sided bezel secured by four functional polished steel screws, alternating between circular satin-brushed surfaces and mirror-polished chamfered bevels. The dial features a vertical-brushed gilded yellow dial face with a vintage-inspired aesthetic. Riveted gilded indices and faceted dauphine hands with Super-LumiNova are complemented by a blued central seconds hand carrying the Maison’s signature Greek letter Phi (Φ) counterweight and a date aperture at 3 o'clock beneath an anti-reflective sapphire crystal. Visible through the exhibition sapphire crystal case back is the in-house Manufacture Baumatic Calibre BM13-1975A. Engineered with silicon escapement technology, it provides magnetic resistance up to 1,500 Gauss, chronometric precision, and a 120-hour (5-day) power reserve. Fitted with an integrated 3-row satin-polished stainless steel bracelet featuring tool-free quick-release interchangeability and a triple-folding clasp with security pushers, it is pressure-tested for 100 metres (10 bar / 10 ATM) of aquatic water resistance and backed by Baume & Mercier’s official 2-year international warranty (extendable to 8 years upon registration).

Design & Craftsmanship

1973 Riviera Heritage & The 39mm Dodecagonal Steel Chassis

First unveiled in 1973, the Riviera broke traditional design conventions by introducing a dodecagonal (12-sided) bezel paired with an integrated silhouette, establishing itself as one of the original Swiss luxury sports watches. In reference M0A10822, Baume & Mercier translates this iconic sports-chic silhouette into a tailored 39.00 mm case format with a 10.21 mm profile. Forged from surgical-grade 316L stainless steel, the case combines circular satin-brushed finishes on the 12-sided bezel with mirror-polished chamfers and vertical brushed flanks. Four functional polished steel screws anchor the bezel, highlighting its geometric character. On the reverse side, an exhibition sapphire crystal case back reveals the mechanical movement and running gear train. The screw-down fluted winding crown is embossed with the Greek letter Phi (Φ)—the horological emblem of the Golden Ratio and divine harmony.
