The centerpiece is the luminous Champagne Dial with Diamonds. This dial features a rich, warm golden hue that perfectly complements the 18K Yellow Gold components. It is typically finished with a sunray pattern, which causes the dial to catch the light beautifully, enhancing its depth and warmth.
The hours are marked by 11 brilliant-cut Diamond Hour Markers (with the Rolex Crown at 12 o’clock), meticulously set in 18K Yellow Gold. These diamonds provide a spectacular sparkle and enhance the watch’s status as a luxurious dress piece, creating a stunning visual harmony with the diamond bezel.
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 highly distinguished timepiece.
