Over the past five years, collectors have come to fully appreciate what a small group always understood; that the most beautiful, unusual, and historically significant Cartier watches were never produced in large numbers, and were often created quietly, for a discerning and highly individual clientele.
This April in Monaco, we are proud to present nearly 40 Cartier watches, spanning the most creative decades of the maison. From London-signed rarities to sculptural Obus cases and experimental forms, this is a selection that captures Cartier at its most daring, and its most collectible.
Here are some of the highlights.
Cartier London Baignoire Allongée, circa 1976 (Lot 36)
Among the rarest of all Cartier London creations, the Baignoire Allongée is a study in proportion pushed to its limit. Produced in extremely small numbers, London examples are already elusive, but to find one preserved with its original deployant clasp elevates it further still. The dramatically elongated case and stretched Roman hours dial transform the watch into an astonishing design piece. A true connoisseur’s Cartier.
Cartier London Baignoire, circa 1964 (Lot 61)
Few signatures carry the same weight as Cartier London. Produced during a period of creative independence, these watches represent some of the most charismatic and unique expressions of Cartier design. This early Baignoire, powered by a Jaeger-LeCoultre movement and preserved in excellent condition, captures the purity of the form. Elegant, restrained, and quietly rare, it is Cartier at its most refined.
Cartier Tank Cintrée, 1950s (Lot 62)
The Tank Cintrée is one of the most important shapes in Cartier’s history. Introduced in 1921, its elongated, curved form remains as striking today as it was a century ago. This 1950s example, with its flowing proportions and warm yellow gold case, embodies the essence of the model. A watch that feels both familiar and special, and one that continues to define timeless design.
Cartier Tank Obus, platinum, 1940s (Lot 67)
The Tank Obus is literally a shot across the case! Defined by its distinctive bullet-shaped lugs, this platinum example is among the rarest iterations of the model. Compact yet assertive, it captures the transition from strict Art Deco lines to something more fluid and 20th century. A subtle, intellectual Cartier that reveals itself fully only to the informed eye.
Cartier Tank Obus, white gold, London (Lot 128)
An early and highly unusual Obus, distinguished by its white gold case and striking blue enamel Roman numerals. Sold through Cartier London, it combines rarity of form with rarity of execution. The vivid enamel detail gives the watch a completely different character; more expressive, more graphic. A reminder that even within rare Cartier, there are further levels of distinction.
Cartier Tank Allongée, white gold, late 1950s (Lot 205)
The Tank Allongée is Cartier at its most experimental. Stretching the Tank silhouette into an elongated vertical form, it becomes less a watch and more an exercise in proportional play. Produced in very small numbers, often on a bespoke basis, examples such as this rarely appear. Intellectual, discreet, and unmistakably Cartier, it rewards those who understand nuance.
Cartier Tank Normale, platinum bracelet, 1930s (Lot 216)
The Tank Normale is the origin of everything that followed. In platinum, and fitted with its original brick bracelet, it becomes something else entirely. Weighty, pure, and perfectly proportioned, this is Cartier in its most distilled form. Examples of this quality and completeness are exceptionally rare, making this one of the most important early Tanks in the sale.
Cartier “Woven Pebble”, white gold, circa 1955 (Lot 240)
Few watches demonstrate Cartier’s freedom of design quite like this. The sculptural, fluted case transforms the watch into an object of art, while the restrained dial anchors it in classicism. Likely unique and published, it represents Cartier at its most daring. A piece that challenges traditional definitions of what a wristwatch should be.
Cartier Tank à Guichets, platinum, 1996 (Lot 287)
The Tank à Guichets has always been one of Cartier’s most radical creations. No hands, no traditional dial; just windows into time. This example, one of only three in platinum made for the 1996 “Magical Art of Cartier” sale, sits at the intersection of history and modern collecting. Rare, conceptual, and deeply important.
A defining moment for Cartier
What unites all of these watches is not just rarity, but intent. These are not mass-produced objects. They are watches conceived as creative designs; experiments in form, proportion, identity, style and fashion. Many were made in very small numbers, some for specific markets, others for specific clients.
Today, the market now fully recognizes Cartier's heritage. It is being studied, collected, and pursued at the highest level. And as collectors look deeper, it is precisely these unusual, rare, and intellectually rich watches that define the future of Cartier collecting.
This April 25 & 26 in Monaco, that story continues…
