Baume & Mercier Classima 31.5mm Ladies Watch

Ref. BM0A10329

The Classima collection draws on the clean geometry of 1960s Swiss dress-watch design, and this reference stays close to that brief: a round case kept to 7.1mm thin, which is genuinely slender for a watch carrying two complications. The moonphase sits behind an arched crescent aperture at the centre of the dial, sharing the space with a date, without the dial feeling crowded — a consequence of the sun-satin silver finish, which gives the surface depth without visual noise. Roman numerals and eight brilliant-cut diamonds take the place of applied indices, pulling the whole thing quietly toward jewellery territory without abandoning legibility. The glossy blue alligator strap is the most characterful decision on the watch. Against the silver case and dial it reads as a deliberate accent rather than a neutral choice, and it sits well against both pale and dark clothing. The Ronda 788 beneath all of this is a compact Swiss quartz calibre with a reputation for accuracy and a very low service footprint — well suited to a watch that will spend years worn, not maintained.

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.

What size strap does it take?

15mm. Any strap of that width will fit, and on most modern watches quick-release bars make the swap a two-minute job with no tools.

Is it a men's or women's watch?

Listed as women's.
