Cartier, best known for its high jewelry, has long been a significant force in watchmaking, largely due to its emphasis on distinctive case shapes and refined design codes. Models such as the Tank, Santos, Ballon Bleu, Baignoire and Asymétrique have become synonymous with the French luxury house. Hallmarks including Roman numerals, sword-shaped hands and sapphire cabochon crowns further distinguish its watches. Whether highly jeweled or resolutely functional, Cartier has carved out a design-led niche that continues to resonate with collectors.
That enduring appeal is underscored by a single-owner collection of more than 300 Cartier watches, now consigned to Sotheby’s. Titled The Shapes of Cartier: A Dream Collection of Vintage Timepieces, the group is described by the auction house as the most comprehensive offering of its kind. The unnamed collector spent approximately 25 years assembling the collection, with a particular focus on pieces from Cartier’s historically independent Paris, London and New York branches. Alongside iconic models, the collection includes several rare and unusual variations.
Sotheby’s will disperse the watches across its Important Watches sales in Hong Kong, Geneva and New York between April and December 2026, with a total estimate exceeding $15 million. The first auction is scheduled for April 24 in Hong Kong, followed by Geneva on May 10 and New York on June 15.
“The appeal of vintage Cartier lies in its ability to capture a moment in design history while remaining entirely timeless,” said Sam Hines, global chairman of Sotheby’s Watches. He emphasized the collection’s depth, particularly its concentration of Cartier London pieces—long regarded as the most experimental output of the brand’s mid-20th-century workshops.
However, the headline estimate of more than $15 million may prove ambitious. While a handful of top-tier pieces—particularly rare London Crash models—could command strong six-figure prices, the collection’s breadth means many watches fall into more modest value categories. With more than 300 lots to absorb, the sales will test the depth of demand for vintage Cartier beyond trophy pieces.
Highlights from the collection to be sold in Hong Kong on April 24 include:
Cartier Crash, London (top photo)
Believed to be one of only three examples produced in 1987, this watch is offered with its original gold deployant buckle, case and accessories. Estimate: $400,000–$800,000.
As detailed by Francesca Cartier-Brickell in The Cartiers, the Crash’s surreal form emerged when Jean-Jacques Cartier and designer Rupert Emmerson distorted the Maxi Oval case, creating one of the brand’s most radical designs. Produced in extremely limited numbers—fewer than a dozen examples are thought to date from 1967–1970—the Crash remains among Cartier’s most coveted models.
Cartier Decagonal, London, yellow gold 10-sided watch. Estimate: $60,000-80,000
Sotheby’s
Cartier Decagonal, London
A rare 18k yellow gold, 10-sided watch hallmarked London, 1970–71. Estimate: $60,000–$80,000.
Sotheby’s has identified only five known examples, all in men’s sizes—an unusual departure for Cartier, which typically produced models in multiple sizes during this period.
Tank Asymétrique, London, white gold with blue numerals. Estimate: $60,000-80,000
Sotheby’s
Cartier Tank Asymétrique, London
An 18k white gold asymmetrical watch, hallmarked London, 1992. Estimate: $60,000–$80,000.
This reinterpretation of the classic Tank rotates the case into a parallelogram form, with a dial designed for angled legibility. First introduced in 1936, the model reflects late Art Deco experimentation and remained a favorite of Jean-Jacques Cartier.
Cartier Asymétrique, London, yellow gold and enamel rear-wound watch. Estimate: $50,000-80,000
Sotheby’s
Cartier Asymétrique with Blue Enamel, London
An extremely rare rear-wound watch from 1973–74. Estimate: $50,000–$80,000.
Produced during Cartier London’s most experimental era (circa 1967–1974), Sotheby’s research suggests only five enamel examples from this period are known.
Cartier Octagonal, London, women’s white gold watch. Estimate: $50,000-80,000
Sotheby’s
Cartier Octagonal, London
An 18k white gold octagonal watch, hallmarked London, 1971–72. Estimate: $50,000–$80,000.
The sharply faceted case, concealed lugs, and matching deployant buckle underscore the workshop’s unconventional approach. While octagonal forms appeared earlier in Cartier pocket watches, wristwatch examples remain scarce.
Cartier Driver’s, London, yellow gold deeply curved rectangular watch. Estimate: $50,000-$80,000
Sotheby’s
Cartier Driver’s, London
An 18k yellow gold curved rectangular driver’s watch, hallmarked London, 1966–67. Estimate: $50,000–$80,000.
Designed for legibility at the wheel, the model reflects Cartier’s longstanding interest in functional design, echoing earlier driver’s watches from the Paris workshop.
Cartier Tank J.J.C Allongée, London, white gold rectangular watch with black dial. Estimate: $40,000-$60,000
Sotheby’s
Cartier Tank Allongée, London
An elongated rectangular white gold watch from 1992. Estimate: $40,000–$60,000.
With its stretched proportions and bold Roman numerals, this example reflects the avant-garde design language associated with Jean-Jacques Cartier’s London atelier.
Cartier London, Baignoire, yellow gold watch circa 1973-74. Estimate: $50,000-$68,000
Sotheby’s
Cartier Baignoire, London
An 18k yellow gold oval watch, circa 1973-74. Estimate: $50,000–$68,000.
Though officially introduced in 1957, the Baignoire traces its origins to a 1912 design by Louis Cartier. It is another example of the London workshop’s individualism and flare for creating unusual variations of iconic Cartier models.
