2000 Cartier Basculante CPCP REF. 2391

The Tank Basculante takes Cartier’s most iconic shape and adds an element of mechanical intrigue. Its vertically rotating case was originally designed to protect the dial during sport, a necessity that modern materials have rendered obsolete—but the mechanism remains both engaging and uniquely Cartier.

This example dates to 2000 and comes from Cartier’s Collection Privée Cartier Paris (CPCP), a period widely regarded as the brand’s modern high point. CPCP watches were produced in limited numbers, built in precious metals, and fitted with mechanical movements at a time when much of Cartier’s lineup leaned toward quartz.

The 25mm solid 18k yellow gold case houses a beautifully finished guilloché dial, adding depth and texture without overwhelming the classic Tank layout. The crystal is clear, and the case shows surface wear consistent with age, along with a few deeper marks on the engraved caseback. There is no indication of polishing.

With its refined CPCP execution and tactile flipping case, this Basculante adds a layer of mechanical charm to the timeless Tank design.
