Baume & Mercier Riviera Skeleton Automatic 42 mm Open-Worked Dial Steel & ADLC-Bezel (10721)

Engineering brilliance and design audacity meet in the Riviera Skeleton 10721 — where Swiss watchmaking becomes wearable sculpture.

The Baume & Mercier Riviera Skeleton Automatic 10721 commands attention from the moment it settles on the wrist. Encased in a bold 42 mm stainless-steel case with the signature twelve-sided bezel — now elevated with visible screws and a sand-blasted ADLC-coated bezel frame — the piece fuses the heritage geometry of the Riviera line with a distinctly modern and technical aesthetic. The thickness of approximately 11.11 mm ensures a presence without overwhelming, while the dynamic interplay of satin-brushed and polished surfaces draws light with sophistication.

Yet the true character of this timepiece lies in its open-worked (skeleton) dial. Rather than hiding the mechanics, Baume & Mercier has laid them bare: the main plate and bridges are carved away to expose the beating balance, the gear trains and the finely finished surfaces within. At 6 o’clock the large balance wheel offers hypnotic motion; at 12 the mainspring barrel’s rhythmic winding is deliberately placed for visual impact. The hour and minute hands — open-worked themselves — hover above this layered architecture, with Super-LumiNova tips ensuring clarity even in low light. The dial’s design carefully retains readability while offering depth and texture: a rare achievement in skeleton watches, where form often compromises function.

Mechanically, the movement is an automatic calibre operating at 4Hz (28,800 vph) with a power reserve of approximately 38 hours. It encapsulates the Maison’s philosophy of combining design daring with horological substance. The transparent sapphire case-back mirrors the bezel’s geometry and offers further insight into the finely finished rotor and the movement’s architecture, reinforcing the watch’s collector appeal.

Completing the composition is a black rubber strap with canvas-effect texture, echoing sport elegance. The strap is designed for tool-free interchangeability — a nod to versatility for the wearer who transitions effortlessly from boardroom presentation to evening refinement. Water resistance of 100 m (10 ATM) affirms practicality alongside luxury.

In sum, the Riviera Skeleton 10721 is not simply a good-looking mechanical watch — it is a statement piece: daring in design, thoughtful in execution, and imbued with the substance that elevates it beyond fashion into horological relevance. For the discerning buyer, it offers both visual theatre and technical integrity: a synthesis rarely achieved at this level.
