Product Description
THE COMPOSITION: EVEROSE ROLESOR
Rolesor is the legendary meeting of two metals that has defined Rolex since 1933. On this model, the bezel, winding crown, and center bracelet links are crafted from 18k Everose Gold—Rolex’s patented pink gold alloy that never loses its red hue, even after years of exposure to chlorine or salt water. The mid-case and outer links are forged from 904L Oystersteel, a superalloy typically reserved for the aerospace industry.
THE DIAL & BEZEL
The Sunray Silver Dial features masterful brushing that creates delicate light reflections moving with the wrist. This serves as the perfect minimalist backdrop for the Diamond-Set Bezel, where Rolex’s in-house gem-setters have hand-aligned each brilliant-cut diamond to maximize light return. The result is a "Sparkling Symphony" that is luminous yet refined.
THE MOVEMENT
Equipped with the Calibre 2236, a new-generation self-winding movement featuring the patented Syloxi hairspring in silicon. This movement is insensitive to magnetic fields and offers a power reserve of approximately 55 hours, ensuring the watch is ready for Monday morning after a weekend off the wrist.
