Visual Description
The Ref. 10715 is a cushion-shaped watch: an 18k yellow gold case, square with rounded corners, about 27 mm wide and 31 mm long. It frames a white dial with black Roman numerals and blued hands, and a blue sapphire cabochon sits on the crown.
The case is thin for its size. Craft + Tailored gives a total thickness of 5 mm excluding the crystal and describes a sloped mineral glass crystal over a white dial signed Paris. Examples have been sold on a black alligator strap and on a Cartier 18k yellow gold Milanese mesh bracelet with a hidden deployant clasp.
Reference Significance
The 10715 is the number under which the Chambord is cataloged, and the only Chambord reference this archive has documented. Every example in the records we found is 18k yellow gold with a white Roman numeral dial; no white gold or platinum version is recorded.
Its interest is its thinness and its shape. The Tank Louis Cartier of those years is rectangular and the Vendôme round; among the gold dress watches of the period in this archive, only the Tortue Ref. 96069 and the bamboo-grooved Coussin Bamboo Ref. 78102 have similarly rounded, cushion-like cases. Craft + Tailored identifies the movement as the ultra-thin Frédéric Piguet Cal. 21, the caliber Archiva records in the Tank Louis Cartier Extra Plate Ref. 96019, which places the Chambord among Cartier's slim hand-wound watches of the period.
Historical Context
Antiquorum dates its example to about 1970, and Craft + Tailored places another in the 1980s. No source we opened gives the year the Chambord was introduced or discontinued, so this page dates it to the 1970s and 1980s.
The caliber number is not settled. Antiquorum records caliber 107, a number that echoes the reference, much as the Tank Louis Cartier Jumbo Ref. 17002 carries the Cartier Cal. 170. The ultra-thin Piguet identification and the 107 may describe the same movement under its maker's number and Cartier's, but no source we opened connects them, so the page gives both.
What to Look For
Start with the case back. On Antiquorum's example the case number, 107150656, runs the reference and serial together, so the number should begin with 10715. Measure the case as well: about 27 × 31 mm and slim. A noticeably smaller cushion-shaped Cartier is a different reference.
Then the movement. It should be hand-wound and signed Cartier, like the dial and case. Every 10715 in the auction and dealer records we found is mechanical, so a quartz movement in this case is a reason to ask questions.
The dial should be white with crisp, even black Roman numerals; uneven or heavy printing suggests a refinish. The thin case and rounded corners show polishing quickly, so look for a crisp outline, even surfaces and clear hallmarks. The crown should carry a blue sapphire cabochon, and a Milanese bracelet should be signed Cartier, with its hidden deployant clasp intact.
