Crafted in a two-tone Rolesor Yellow Gold style, the outer links are in Oystersteel while the inner links are in polished 18K Yellow Gold. The bracelet fastens securely with the folding Oysterclasp.
The centerpiece is the ethereal Mother-of-Pearl Diamond Dial . Mother-of-Pearl is a natural material, ensuring every dial is unique, shimmering with iridescent colors that change subtly with the light. This inherent natural beauty makes it highly prized.
The hours are marked by 10 brilliant-cut Diamond Hour Markers (with the Rolex Crown at 12 o’clock and a date window at 3 o’clock), meticulously set in 18K Yellow Gold surrounds. These diamonds enhance the dial’s inherent sparkle. The date is displayed at 3 o’clock, magnifying beneath the Cyclops lens.
Under the dial lies the robust and precise Calibre 2236 movement. This self-winding mechanical movement incorporates the patented Syloxi hairspring, providing exceptional performance, accuracy, and reliability, and is certified as a Superlative Chronometer, completing this distinguished timepiece.
