Visual Description
The Ref. 78090 is a 33 mm Vendôme in 18k yellow gold. Loupe This calls the case slightly oval, and Monaco Legend measured its white gold example at 34 mm wide by 29 mm long.
The white dial carries black Roman numerals and a railroad minute track under blued steel hands, and the crown is set with a cabochon. Catalogs show the watch on a leather strap, one with an 18k gold Cartier deployant clasp.
Reference Significance
The 78090 is the 33 mm manual-wind Vendôme in gold. The other Vendômes in this archive are quartz: the 24 mm vermeil Must de Cartier Ref. 590004 and the 24 mm 18k gold Ref. 881002. A smaller 26 mm manual gold Vendôme appears in Analog/Shift's sold archive as Ref. 67080.
The oval watch of the same Louis Cartier Collection size is the Ellipse Ref. 78091, so check the shape of the case against the number on the back.
Historical Context
Loupe This dates the launch to 1973, as part of the Louis Cartier collection, while Monaco Legend's catalog essay says the Vendôme was introduced in the late 1970s. Dated examples run from a white gold watch of circa the 1970s to yellow gold examples of the 1980s, and no source found gives the year production ended.
Antiquorum and Monaco Legend both catalog the movement as cal. 2512 with 17 jewels.
What to Look For
Check which metal and bezel the watch has: yellow gold, white gold and a mother-of-pearl and diamond bezel have all been cataloged under 78090. Antiquorum's example has the case number 780902006, the reference followed by the serial.
Ask for a photograph of the hand-wound movement, which catalogs give as cal. 2512 with 17 jewels, and check the cabochon in the crown.
