Housed in a 36mm steel case measuring 9.46mm thick, the Ronde Solo de Cartier reference WSRN0021 pairs a silvered opaline dial with blued-steel sword-shaped hands for a quietly refined look. The crown is beaded steel and set with a synthetic cabochon-shaped spinel, while a sapphire crystal protects the dial face. Water resistance is rated to 3 bar, approximately 30 meters or 100 feet.
Power comes from a mechanical movement with automatic winding, delivering dependable everyday performance within Cartier's iconic round case shape. The strap is a black grained calfskin interchangeable design secured by a steel double adjustable folding buckle, allowing for a comfortable and versatile fit on the wrist.
This piece is offered as an unworn example in a complete set, inclusive of the original Cartier box and Cartier papers — ideal for the collector who values full provenance alongside a classic and enduring design.
