Visual Description
The Ref. 78096 is the large Cristallor, a 28 × 35 mm case about 6 mm thick. Its rectangle has canted corners that give it an octagonal outline, the bezel steps down to the dial in three tiers, and the lugs are hidden beneath the case. Sotheby's and Monaco Legend both catalog it at 28 × 35 mm.
The dial is white lacquer with black Roman numerals and a minute track, signed Paris, with blued steel sword hands. The beaded crown carries a blue cabochon and the back is held by four screws. Most examples are 18k yellow gold and a few are 18k white gold. They come on leather straps with an 18k gold Cartier deployant clasp or tang buckle.
Reference Significance
The 78096 is the Cristallor in its larger size, which is why Sotheby's and Monaco Legend catalog it as the Cristallor Jumbo. At 28 × 35 mm it is 4 mm wider and 5 mm longer than the Ref. 78095.
Where its 1973 siblings the Vendôme and the Fabergé use round and curved forms, the Cristallor is built from flat facets and steps. The white gold version is the rare one: Phillips found no more than a handful of white gold examples on the market.
Historical Context
The Cristallor was introduced with the Louis Cartier Collection in 1973. Craft + Tailored writes that it arrived alongside the Gondole, the Ellipse and the Vendôme, and that it was made only until the very early 1980s.
Catalog dates fit that window only loosely: Sotheby's dates one example to circa 1970, a few years before the collection's launch, and Phillips a white gold example to circa 1975. Production was small: one auction house estimates from serial numbers that fewer than 1,000 Cristallors were made, and some examples still surface with their original Cartier warranty, box and hang tag.
What to Look For
Start with the bezel. The three tiers should have crisp edges, because polishing softens the steps and cannot be reversed. Wind Vintage singles out an unpolished case, which is the condition to look for.
Turn the watch over. Phillips and Aguttes record case numbers that begin with the reference and continue with the serial (780960345 and 780960105). One example has been offered with the numbers G24314 and 0471 instead, so a case without the 78096 prefix calls for a careful look at the movement and dial rather than an immediate rejection. The movement should be the hand-wound Cal. 78-1 signed Cartier; a quartz movement is not original.
On the dial, expect white lacquer signed Paris. Fine cracks in the lacquer come with age, while heavy or uneven printing suggests a refinished dial. A dial signed SWISS has also been documented and described as original. The clasp should be an 18k gold Cartier deployant or tang buckle in the case metal.
