Aesthetic Design and Finishing Excellence

This Datejust features a 31mm Oystersteel case complemented by a fluted white gold bezel, embodying White Rolesor—a Rolex innovation fusing steel’s resilience with gold’s nobility. The bright black dial is crafted through Rolex’s lacquering mastery: six thin layers deposited on a brass base in a controlled environment for flawless uniformity, followed by a colourless varnish and hand-polishing to achieve profound intensity and a smooth, mirror-like shine. Pad-printed inscriptions and appliques complete the sleek surface. The date at 3 o’clock is magnified by the Cyclops lens, while scratch-resistant sapphire crystal safeguards these impeccable details—highlighting Rolex’s expertise in creating limitless color freedom and enduring beauty.
