The Secret Signature
Introduced 1977
A microscopic 'CARTIER' hidden within the Roman numerals, present on every genuine post-1977 dial.
Cartier's oval wristwatch: hand-wound in gold in the 1960s and 1970s, reissued as the Allongée in 1991, and quartz in the 1990s.
Baignoire is French for bathtub, after the oval shape of the case. In England, Sotheby's notes, the same watch was called the Oval.
The model's date is disputed. Fellows writes that the Baignoire was introduced in 1912, and Monaco Legend that Louis Cartier made an oval wristwatch for Grand Duchess Maria Pavlovna of Russia in the 1910s.
Sotheby's catalogs put the official launch in 1956 or 1957, and every Baignoire on Archiva dates from about 1960 or later.
Cartier London retailed the oval in three documented sizes, from about 25 × 19 mm to about 36 × 23 mm, in 18k gold and hand-wound on LeCoultre movements. These London Baignoires carry English hallmarks with a date letter and are cataloged by case or stock number rather than a reference; dated examples run from about 1964 to 1974.
The Ref. 7672 is a number printed only by Sotheby's, which sold Oona Chaplin's 31 × 23 mm yellow gold example, a gift from Charlie Chaplin, in December 2023. Its catalog note called the watch a Baignoire Paris; a saleroom notice then corrected it to a Cartier London piece, with hallmarks inside the case and a Jaeger-LeCoultre movement.
The Ref. 78094 is a hand-wound gold oval identified by its reference number rather than by hallmarks: about 22 × 31.5 mm, most often in yellow gold, on the Cartier Cal. 78-1, with dated examples from about 1970 to 1991. Cambi catalogs one as produced in Paris.
From the late 1960s Cartier London also retailed the Baignoire Allongée, the oval drawn out to about 23–24 × 52–53 mm, more than twice as long as it is wide, on a hand-wound Jaeger-LeCoultre movement. Dated examples carry London hallmarks for 1969 and run to about 1976, and each is identified by its case number. Bonhams describes these watches as entirely handmade in Cartier's London workshop.
The Allongée is linked to the Crash: Phillips calls it the muse behind the Crash, and Sotheby's describes the Crash as the Allongée with its sides pinched and its middle kinked.
In 1991 Cartier reissued the Allongée as the Ref. W1507451, a numbered edition of 400 in 18k yellow gold at 23–24 × 52–54 mm on the Cartier Cal. 78-1.
From about 2000 Cartier made a shorter Allongée, 47 mm long and hand-wound on the Cartier Cal. 060 MC: the Ref. 2514 in white gold and the Ref. 2515 in pink gold, which share one series of case numbers ending AF. The Ref. 2605 is the same 47 × 21–22 mm Allongée in 18k yellow gold on a quartz movement, with case numbers ending AF and dated examples from about 1999 to 2005.
The Ref. 1954 is the Baignoire of the 1990s and 2000s: a 23 × 31 mm 18k yellow gold oval on the quartz Cartier Cal. 057, with a silvered dial, a sapphire crystal and the hidden Cartier signature at 10 o'clock.
The Ref. 1967 is a smaller quartz oval of the 1990s, 20 × 27–28 mm in 18k yellow gold, cataloged on a gold bracelet of oval links and most often with a diamond-set bezel. Its number is a reference, not a year.
Read the marks inside the case back first: English hallmarks and a London date letter place an oval with Cartier London. Then measure: about 25 × 19 mm, 31–31.5 × 23 mm or 35–36 × 23 mm for the London ovals, about 23–24 × 52–53 mm for the Allongée and 23–24 × 52–54 mm for its 1991 reissue, 47 × 21–21.5 mm for the Allongées of the 2000s, the Refs. 2514 and 2515, and 47 × 21–22 mm for the quartz Ref. 2605, about 22 × 31.5 mm for the hand-wound Ref. 78094, 22.5 × 31 mm for the quartz Ref. 1954 and 20 × 27–28 mm for the quartz Ref. 1967. The movement confirms the era: hand-wound and signed Jaeger-LeCoultre or LeCoultre Co. on the London ovals, the Cartier Cal. 78-1 on the 78094 and the 1991 edition, the Cal. 060 MC on the 2514 and 2515, and quartz on the 1954, 1967 and 2605.

The London Baignoire is the 18k gold oval retailed by Cartier London c. 1964–1974, hand-wound on the LeCoultre Cal. 840 or K840 and identified by its London hallmarks rather than a reference number. Three sizes are documented, from about 25 × 19 mm to 36 × 23 mm, most often in yellow gold with a cream, silvered or white dial.

Sales from November 2023 to November 2026, or from the last five years for a reference with fewer than three in that time. Only sales that name a reference count toward its estimate; sales of the rest of its version are shown for comparison and never folded in. Auction prices include the buyer's premium unless a row says hammer; dealer prices are the price at sale. Currency figures are converted near the sale date; Dorotheum figures include its premium and VAT. EveryWatch does not say whether its figures include the premium. Rows via EveryWatch, Collector Square or lot-art come from those indexes and should be confirmed at the auction house. The condition and option adjustments, the expected bid (75 to 85% of market value) and the auction range (62 to 72%) are working assumptions, to be replaced by Archiva's own bids as they come in. A sale far above or below the other sales of its reference is listed but not counted, so one unusual result can't pull the estimate. An estimate from public results, not an appraisal.
What every buyer, inheritor, and first-time collector should know.
Introduced 1977
A microscopic 'CARTIER' hidden within the Roman numerals, present on every genuine post-1977 dial.
Varies by origin and era
A Cartier case carries the Cartier signature, a reference and serial number on later pieces, and small struck marks for the metal and the case maker. Which marks appear depends on where the case was made: an eagle's head on Paris gold, JC and a date letter on London cases, the Helvetia head on Swiss 18k before 1995. The hallmarks guide shows what each one means.
Varies by era and model
Cartier sourced movements from various Swiss manufacturers throughout history, including Jaeger-LeCoultre, Frédéric Piguet, ETA, and in-house production. Knowing the correct caliber for a specific reference is essential for identifying the watch and establishing provenance.
A Cartier hallmark since the early 20th century
The blue sapphire (or spinel on less precious models) cabochon crown is a Cartier signature. Original crowns show consistent color saturation and are set flush with the crown body. Replacements often show misalignment or incorrect stone dimensions that reveal themselves under magnification.
Check the clasp first
Cartier bracelets carry their own reference markings and the deployment clasp should bear the Cartier name and logo. Aftermarket bracelets are extremely common on vintage pieces, so checking that the clasp is original and that reference numbers match is crucial to the overall picture.
Patina tells the story
Vintage Cartier dials develop characteristic aging: cream dials warm to ivory, lacquer dials may develop fine crazing, and applied indices can show legible wear patterns. Understanding acceptable versus concerning dial aging is key to valuing a vintage piece accurately.
