Stepping up in the same dial colour
The Joia arrived in 2026 as Baume & Mercier's first collection built around an explicitly jewellery-led brief — a watch drawn closer to the wrist by a lugless case where the bracelet flows directly into the case without interruption. The crown set with a black agate cabochon is the detail that announces the intent most clearly, a material choice that belongs to fine jewellery rather than conventional watchmaking. At 28mm the dial is intimate, and the sun-satin silver surface rewards that closeness: Roman numerals sit against it with quiet formality, while the 4N gold-tone leaf hands introduce a warmth that prevents the whole from reading as purely cold and metallic. The case comes in at 7.2mm, flat enough to disappear beneath a cuff. The three-row bracelet, built from H-shaped links in alternating polished and satin steel, sits flush and moves without stiffness, and the spring-bar system allows the bracelet to be swapped without tools — useful for a watch the collection clearly intends to be worn in different configurations. The Ronda 751 movement running inside is chosen for efficiency over complication, offering a five-year battery life — practical for something worn as much for how it looks as for what it does.

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 women's.
