More about Cartier:

In the 1990s, Cartier introduced the Collection Privée Cartier Paris (CPCP) in an effort to revitalize its reputation as a true, creative watchmaking house. A new focus on the development and production of high-quality, in-house movements is at the heart of the CPCP.  Visible through its exhibition case back, the double “C” insignia of the CPCP beautifully decorates the plates of the present watch. 

On the dial side, which is divided between retrograde hours and minutes, features an engraved disc, which rotates to show either a sunny sky, indicating daytime, or a moonlit one, indicating night.
