Stepping up in Baume & Mercier's range
The Promesse collection sits at the dressier end of what Baume & Mercier makes, and this variant pushes further still: diamonds set into the bezel around a mother-of-pearl dial, then a cobalt-blue leather wrap strap underneath it. The contrast is the decision — the cold iridescence of the dial against a strap colour that has no business being that bold, and somehow the combination holds. On the wrist it reads as jewellery first, and the wrap strap gives it a relaxed fit that a standard pin-buckle would not. The mother-of-pearl shifts between white and grey depending on the light, which keeps the dial from feeling flat.

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 women's.
