About This Watch

The Rolex Datejust 31, introduced in 2020, embodies the enduring elegance of the Datejust collection, first conceived in 1945 as a timepiece that harmonized precision with refined aesthetics. This particular model distinguishes itself through a striking blue sunburst dial, its hue deepened by the interplay of light across the polished surfaces of Roman numeral indexes and slender stick hands. The case, crafted from stainless steel, is framed by a diamond-set white gold bezel, a subtle yet deliberate nod to the collection’s tradition of blending precious materials with enduring durability. The Jubilee bracelet, with its signature five-link design, complements the watch’s balanced proportions, ensuring both comfort and a sense of quiet sophistication. At its core, the Datejust 31 houses the Caliber 2236, a self-winding movement that combines Rolex’s hallmark in-house engineering with a date display and hacking seconds—a feature that allows the hands to stop for precise time setting. The sapphire crystal, paired with a water resistance rating of 1
