Stepping up in Baume & Mercier's range
The Riviera 73 sub-collection, launched in 2026, exists to mark fifty-three years of a shape that was genuinely original: Jean-Claude Gueit's twelve-sided case from 1973, which appeared at a moment when integrated sport-luxury watches were still a novelty. This reference reproduces that dodecagonal bezel without screws, exactly as the first generation had it, and the 7.65mm case thickness places it firmly in dress-watch territory — slimmer than the mechanical siblings in the same family, and comfortable under a shirt cuff in a way that the heavier Riviera variants are not. The white opaline dial carries a wave motif pressed into its surface, which shifts between flat and textured depending on where the light falls, and the Roman numerals are ruthenium-plated — darker than polished steel, cooler than gold, and correctly matched to the satin-finished case. The caseback is the detail an owner will notice eventually: screwed down, engraved with "73" against vertical striping that references the deck planking of a boat — which is where the Riviera name always pointed. The three-row bracelet is integrated and built to release without tools, and the triple folding clasp with push-button safeties means it fastens with more ceremony than the watch's restrained appearance might suggest.

Learn more about Baume & Mercier
The Baume brothers opened a watchmaking business in Les Bois in the Swiss Jura in 1830, and built a substantial export operation through a London office. The company won significant honours at nineteenth-century observatory trials, including a record for a chronograph tourbillon at Kew that stood for years.
The modern company dates from 1918, when William Baume partnered with Paul Mercier in Geneva. Mercier brought design sensibility, and the house's Art Deco pieces of the 1920s — shaped cases, jewelled dials, and the Phi emblem representing the golden ratio — established a decorative direction it has largely kept.
Baume & Mercier was among the founding members of the Geneva Seal system and produced complications including minute repeaters and perpetual calendars in its earlier decades.
Its modern position is deliberately accessible: classical Swiss watchmaking at prices below the group's luxury tier, with the Clifton, Riviera, and Hampton collections covering round dress watches, integrated-bracelet sports watches, and rectangular Art Deco shapes respectively. The Riviera, introduced in 1973, was among the first steel luxury sports watches with an integrated bracelet, arriving a year after the Royal Oak.
The house has been part of Richemont since the group's formation, and produces around two hundred thousand watches annually.

Frequently asked questions, and things you should know about this watch
Can I swim with it?
Showering yes, swimming no. 50m covers splashes and brief immersion, but a swimming stroke generates well above the pressure that figure describes.
Will the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Does it need a battery?
Yes. It is quartz, so expect a battery change every two to three years at a jeweller.
Is it a men's or women's watch?
Listed as men's, though at 39mm it sits in the range that suits anyone.
