Created as part of the celebrated Collection Privée Cartier Paris, the Tank à Vis Dual Time Ref. 2551 brings together three defining Cartier qualities: architectural design, mechanical sophistication and restrained elegance.

The CPCP collection marked Cartier’s renewed emphasis on the historic case designs and mechanical watchmaking traditions that established the Maison as one of the twentieth century’s great watch creators. Produced in precious metals and powered by carefully selected mechanical calibers, CPCP timepieces were conceived for collectors who appreciated Cartier not only as a jeweler and designer, but also as a serious watchmaker.

The Tank à Vis takes its name from the visible screws integrated into its distinctive case architecture. In the Ref. 2551, Cartier combines that construction with an exceptionally well-balanced dual-time display. Two vertically arranged guilloché registers feature black Roman numerals, railway minute tracks and blued steel sword hands. Despite displaying two separate time zones, the dial remains formal, symmetrical and unmistakably Cartier.

The watch is powered by the manually wound Cartier Calibre 9901 MC, developed from a Piaget ébauche and adapted specifically for the dual-time function. Both displays are operated through a single movement and sapphire cabochon-set crown. The lower hour indication may be advanced independently, allowing a second time zone to be set without disturbing the principal display. Visible through the sapphire exhibition caseback, the movement is decorated with the repeating double-C motif associated with the CPCP collection.

Dating to approximately 2006, this example is accompanied by its Cartier presentation box, certificate and accompanying papers and booklets. The 18K yellow gold case is fitted with a burgundy Cartier leather strap and signed Cartier 18K yellow gold deployant clasp.

Condition: This timepiece presents in very good overall condition, with light signs of careful wear consistent with its age.
