Movement and Escapement

Power is provided by the Calibre 492 MC, a rhodium-plated movement containing 30 jewels. The movement is characterized by a lateral lever escapement that integrates a one-minute tourbillon regulator. The tourbillon itself is mounted within an A-shaped polished steel cage, designed to rotate fully once per minute. This mechanism uses a monometallic balance combined with a self-compensating Breguet balance spring to address potential positional timing errors. The visual presentation of the movement is an integral part of the watch's aesthetic, as the skeletonized structure allows for the components to be observed through the transparent dial.

Case and Dial Construction

The timepiece is housed in a solid, three-body 18K pink gold case measuring 38 mm in diameter. It is designed to be water-resistant and features a wide, sloped bezel that frames the transparent dial. The design integrates square "Vendôme"-style lugs secured with pink gold screws, providing a distinct profile. Access to the movement is provided by a case back secured with eight screws, which also incorporates a porthole allowing for a view of the tourbillon cage. The transparent dial provides a direct view of the underlying mechanism, featuring a single grid bridge and a central square minute track finished in pink gold. The time is marked by painted indexes and skeletonized Arabic numerals at the 3 and 9 o'clock positions. Burnished pink gold lozenge-shaped hands are utilized for the time display, complementing the overall metallic finish of the dial ensemble.

Signatures and Authenticity

The watch is catalogued under lot number 27 and carries the reference number 2578. It is specifically identified as part of the Cartier Collection Privée, with markings on the case back indicating its place within the limited edition. The auction description explicitly states that the dial, case, and movement are signed by the manufacturer. The case and movement are both assigned a grade of 2, indicating they are in very good condition. The dial is given a grade of 1-01, described as being in "as new" condition, and the hands are verified as original.
