One of the most emblematic and classic watch cases of the early 20th century is the Tortue. Designed by Louis Cartier in 1912, the rounded tonneau-shaped case was elegant and sophisticated and named “tortue à pattes” or “turtle on legs” both for its similarity to the animal’s shape and symbolism of good fortune and longevity. Cartier has long used the case since its introduction, and in 1998 they introduced their Cartier Privée Paris Collection (CPCP) Tortue Monopoussoir chronograph. The collection sought to bring modern watches to collectors who wanted a vintage look. Available from 1998 until 2008, the collection was based on their legendary designs that have made the brand so famous and sought after amongst collectors.

The first monopoussoir, or monopusher, chronograph was released by Cartier in 1928 and the modern edition remains close to the original, but with a larger, more contemporary case featuring the manual caliber 045MC, interestingly co-developed by F. P. Journe, Denis Flageollet and Vianney Halter. The case has a classic look with the single button chronograph operated through the crown giving the watch a clean, uncluttered appeal.
