Housed in a 36mm steel case measuring 9.46mm thick, the Ronde Solo de Cartier WSRN0012 carries the clean, circular lines that define this storied collection. The steel crown is beaded and set with a synthetic cabochon-shaped spinel, a refined detail that reinforces the watch's considered construction.
The silvered opaline dial is read through a sapphire crystal, its surface animated by blued-steel sword-shaped hands. The watch is water-resistant to 3 bar, approximately 30 meters or 100 feet, and runs on an automatic winding mechanical movement.
The piece is presented on a leather strap, lending a classic contrast to the steel case. As with all Cartier creations, subtle variation in stone count or carat weight may occur from one piece to the next.
