Vintage Baume & Mercier Ladies 18k White Gold Dress Watch, Rare Diamond Set Boutique Edition (c. 1970’s)

A NOTE FROM THE CURATOR

Founded in 1830, Baume & Mercier has a rich history of blending traditional Swiss watchmaking with elegant, jewellery-inspired design. Particularly noteworthy are the brand's ladies' creations, dating back to the Art Deco era and continuing through the 1970s and 1980’s with imaginative collections such as the Stardust, Galaxie, and the Avant Garde. It’s in these two decades in particular they the brand had embraced the era's appetite for luxurious, integrated gold watches.   

This exceptional Boutique Edition beautifully captures the spirit of the time, pairing a dazzling diamond-set dial and bezel with an exquisitely crafted, integrated braided rope gold bracelet, a design reminiscent luxury contemporaries such as Piaget. In fact, many don’t know that Baume & Mercier was actually owned by Piaget from 1964 until 1988, before both brands came under Cartier's control. During this period, Baume & Mercier embraced many of the era's most iconic luxury design cues, creating watches that blurred the line between fine jewellery and traditional horology. This exceptional piece is a wonderful expression of that philosophy, from a time when a ladies' watch was as much a work of exquisite jewellery as it was a precision timepiece.

What makes this particular example especially compelling is its remarkable preservation. Intricate gold bracelets are notoriously susceptible to wear and distortion if not cared for or stored properly, yet this example retains exceptional definition, brilliance, and firmness. Coupled with its extraordinary diamond-set dial and bezel, and single-family provenance, it is a wonderfully preserved expression of 1980s Swiss jewellery watchmaking.

THE BRILLIANT DETAILS

This rare and exquisite 1980s ladies' Baume & Mercier Boutique Edition comes to us directly from the family of its original owner, who treasured and meticulously cared for it as a cherished heirloom. Beautifully crafted in solid 18K white gold, this exceptional timepiece features a spectacular diamond-set dial and bezel, complemented by an intricately crafted, integrated white gold bracelet.

The extraordinary diamond-set dial is a particular highlight, pavé bead-set with 68 single-cut diamonds totalling approximately 0.68 carats. Unlike conventional diamond hour markers, here the entire dial is adorned with diamonds, creating a brilliant, textured surface that totally comes alive in the light, with a captivating sparkle that these photographs hardly capture (I'm embarrassed to say). 

Surrounding the dial are 32 prong-set round brilliant-cut diamonds, weighing approximately 0.96 carats. Together, the dial and bezel feature 100 diamonds totalling approximately 1.64 carats, graded with an average of VS clarity and F–G colour, as documented in the accompanying independent gemological appraisal.

Equally impressive is the integrated 18K white gold braided rope bracelet, with its crisp, vibrant finish and beautifully preserved texture. Remarkably, the bracelet and case appear unpolished, and hardly worn, retaining their original definition and meticulous craftsmanship.

Measuring 17.5cm (6.89 inches) in length, the watch is best suited to a wrist no larger than approximately 16cm (6.29 inches).

Inside is a reliable Swiss ETA calibre 2512 hand-wound mechanical movement, serviced while under the care previous owner in May 2025 - the movement is running beautifully.

CONDITION

This exceptional Baume & Mercier is presented in fabulous pre-owned vintage condition.

The diamond-set dial, bezel, and white gold bracelet are immaculate, remarkably clean, crisp, and vibrant. All original diamonds are present and intact.

The case and bracelet appear to remain unpolished, with deep, crisp, and untouched serial engravings and gold hallmarks. Only minor superficial surface wear is visible on the caseback, consistent with careful ownership and wear over the past four decades.

The overall condition is particularly impressive for a vintage gold jewellery watch of this age, especially given the delicate and intricate construction of its integrated bracelet, and diamond-set detailing.
