Cartier Tortue Monopoussoir CPCP

About this reference

The Cartier Tortue Monopoussoir reference W1525751 in 18k yellow gold was produced between 1998 and 2008 as part of the Collection Privée Cartier Paris (CPCP). Collectors prioritize this reference for its caliber 045MC, a manual-wind monopusher chronograph movement developed by THA Èbauche, a collaborative firm founded by Vianney Halter, Denis Flageollet, and François-Paul Journe. The 34mm x 43mm case features a guilloché dial with the "Paris" signature and a blued steel Breguet-style handset. Secondary market prices typically range from $45,000 to $65,000 depending on the presence of original accessories. While the yellow gold version is the most common metal for this reference, production numbers remained low compared to standard Cartier lines. A notable auction result occurred in May 2024 at Phillips Geneva, where a well-preserved example achieved 50,800 CHF, reflecting the sustained demand for early CPCP complications.
