Visual Description
The Ref. 1460 is a round 18k yellow gold Diabolo, 32 mm across and, per Antiquorum, 9 mm thick. Antiquorum describes a two-body case, polished and brushed, with a rounded bezel, straight screwed lugs, a cabochon sapphire-set crown, a back held by six screws and a domed sapphire crystal; Bonhams also records the six-screw back and the cabochon crown.
Dials are white, silvered or champagne, with Roman numerals. Stahl and Bonhams record white dials with black Roman numerals. Antiquorum catalogs a silvered guilloché dial with painted radial Roman numerals, an outer minute track and an inner ring of 24-hour numerals, and Bulang & Sons another silvered guilloché dial. The hands are blued steel in the Breguet style, and examples come on leather straps with an 18k gold Cartier folding clasp or pin buckle.
Reference Significance
The 1460 is the hand-wound counterpart of the quartz Ref. 1420. Both are yellow gold Diabolos about 32 mm across, but the 1460 runs on the Cartier Cal. 9P2 with 18 jewels, which Bonhams, Antiquorum and Bulang & Sons all name. Antiquorum catalogs it as the Diabolo Mécanique, and one example sold by Stahl has a champagne dial signed Cartier Mécanique.
The same caliber appears under other numbers: Antiquorum catalogs a white gold Diabolo Mécanique with a diamond-set bezel as Ref. 1464. In yellow gold, Bonhams has offered a 1460 with a diamond-set bezel, 33 mm across.
Historical Context
Monaco Legend writes that the Diabolo model was launched in 1991. Stahl dates one 1460 to around 1990, and Bonhams and Bulang & Sons date others to about 2000, Bulang & Sons from a serial in the C102 range. Antiquorum, cataloging an example in 2010, dated it to the 1980s, earlier than any other record of the reference. No source we opened gives an end date.
Bulang & Sons writes that the hand-wound version was released in the Collection Privée Cartier Paris; the auction catalogs consulted do not use that name.
What to Look For
Start with the case back. Stahl records one marked "Cartier Water Resistant 100 ft/30m Swiss Made 18" and numbered 1460 0. Case numbers recorded on 1460s include R2797 (Bonhams), C70181 (Stahl) and a C102 serial (Bulang & Sons).
Then the movement: a hand-wound Cartier Cal. 9P2 with 18 jewels, and Antiquorum and Bonhams record case, dial and movement as signed. A quartz movement with a date points to the 1420. Check that the sapphire cabochon in the crown is present and that the Roman numerals are crisp, and look for an 18k gold Cartier folding clasp or pin buckle.
