Measuring 42mm in diameter and just 8.53mm thick, the Ronde Solo de Cartier W6701009 houses a mechanical automatic movement within a case crafted from 18k pink gold and steel. The crown is adorned with a synthetic cabochon-shaped spinel, and the sapphire crystal offers a clear view of the refined silvered opaline dial below.
Blued-steel sword-shaped hands sweep across the dial, while a calendar aperture positioned at 3 o'clock adds a practical complication to the composition. The case is water-resistant to 3 bar, approximately 30 meters or 100 feet.
An alligator-skin strap with round scales completes the watch, fastened by an 18k pink gold ardillon buckle that carries through the warmth of the precious metal from case to wrist.
