Baume & Mercier Riviera 36mm Unisex Watch Mother Of Pearl
Ref. M0A10662
Sits in Baume & Mercier’s upper tier here — more premium than three quarters of the Baume & Mercier watches we list, which start at £850.
Price range £850 to £18,000 across 47 Baume & Mercier watches in stock.The Riviera collection dates to 1973, and its defining feature has always been that twelve-sided case — a shape that sits somewhere between the angular sports watches of that era and something more decorative. This modern interpretation keeps the dodecagonal silhouette intact and pairs it with a bezel set with 44 diamonds in a snow setting, held by four polished screws against a sun satin-finished surround. The dial is white cultured mother-of-pearl with a transparent wave pattern worked into its surface, which means the iridescence shifts rather than simply glows as the light changes. Dauphine hands and mixed indices carry Super-LumiNova, so legibility holds after dark. The integrated bracelet is designed to be self-interchangeable, and the push-button triple-folding clasp means it goes on and off cleanly without tools.

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.
Water resistance explainedWill the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Sapphire, mineral and acrylic comparedDoes it need a battery?
Yes. It is quartz, so expect a battery change every two to three years at a jeweller.
Quartz, automatic and solar comparedIs it a men's or women's watch?
Listed as unisex, and at this size it suits any wrist that takes the dimensions.
