About this watch

Created by Louis Cartier in 1912, the Tortue was only Cartier’s third wristwatch design, after the Santos Dumont and the Tonneau, and before the Tank which was introduced in 1917.

As a series of mechanical watches based on historic Cartier designs, the Collection Privée Cartier Paris demonstrated what Cartier was capable of producing in terms of iconic designs. Most of the models within the CPCP collection were available between 1998 and 2008, in limited numbers, using mechanical movements from external suppliers. CPCP pieces are among the most sought-after by collectors.

One of the rarest and most fascinating pieces in the CPCP collection is undoubtedly the present Perpetual Calendar model.

The production of these watches, especially in platinum, is extremely limited. The massive platinum case is bigger than the classic other Tortue CPCP models, and this obviously derives from the caliber 9421MC, and the complications it contains. It is in fact, a perpetual calendar. The caliber 9421MC is based on a Girard Perregaux movement equipped with a Dubois Depraz perpetual calendar module. The dial has a guilloché decoration, large Roman numerals, the secret signature at 7 o’clock and four sub-dials that indicate the month combined with the display of the year leap, the day, date and 24 hour dial for the second time zone.

The combination of Cartier design and the extraordinary perpetual calendar complication explains the appeal of this extremely rare Tortue amongst watch collectors of today. It is in perfect condition, with its original Cartier alligator strap and 18K white gold deployant clasp. It is presented full set with its original box and papers.
