Visual Description
The Ref. 78095 is the small Cristallor, a 24 × 30 mm case in 18k yellow gold. Monaco Legend writes that it takes the rectangular form and sculpts it into three ascending tiers, and Antiquorum describes a vertical rectangle with cut corners.
The dial is white with Roman numerals and signed Paris; Antiquorum describes one as ivory. Monaco Legend notes sword hands and Bachmann & Scher blued steel hands. Monaco Legend's example came on a leather strap, and Antiquorum's with an 18k yellow gold Cartier deployant clasp.
Reference Significance
The 78095 is the smaller of the two Cristallor sizes. At 24 × 30 mm it is 4 mm narrower and 5 mm shorter than the Ref. 78096, which Sotheby's catalogs as the Cristallor Jumbo at 28 × 35 mm. Analog/Shift has sold the smaller size as the Cristallor Junior.
Every 78095 in the records consulted is 18k yellow gold with a white dial and a hand-wound Cal. 2512, which Antiquorum names as the ETA 2512. No white gold example is documented.
Historical Context
Monaco Legend writes that the Cristallor was born in the early 1970s within the Louis Cartier Collection, and that production is believed to have ended by the early 1980s. The dated examples fall in that window: Bachmann & Scher dates its 78095 to 1975, Monaco Legend its own to the 1970s and Antiquorum one to circa 1970 to 1980.
What to Look For
Start with the case back. The case number should begin with 78095, as on the 780950699 that Antiquorum recorded; Monaco Legend printed only the serial, 392. Antiquorum's catalog title gave that watch as Ref. 25720, but its case number, size and Cristallor model line are those of the 78095, so go by the number on the case rather than a catalog heading.
The movement should be a hand-wound Cal. 2512, and Monaco Legend and Antiquorum record case, dial and movement as signed. Expect a white dial with Roman numerals, signed Paris. Check the edges of the three tiers, which show any polishing, and measure the case: 24 × 30 mm is the 78095, and 28 × 35 mm is the Jumbo.
