Launch Dial
Tortue Monopoussoir CPCP 2356 — Launch Dial
The first configuration, re-released in April 1999: the most faithful to the 1920s original, with Roman numerals in a circular track and empty corners.
A Collected Man (citing Nick Foulkes) puts output at around 200 Tortue Monopoussoirs a year across all configurations, just under 2,000 in total.

Movement
Cartier 045 MC
Hand-wound single-button chronograph developed for the CPCP Tortue and Tank monopoussoirs by THA Ébauche (François-Paul Journe and Denis Flageollet, later joined by Vianney Halter). Uses a swivel-pin clutch that avoids the jolt of the seconds hand on start.
