About This Watch

Among Rolex's most artfully composed mid-size references, the Datejust 31 in White Rolesor represents a seamless marriage of Oystersteel and 18-carat white gold that elevates everyday wear into an expression of understated luxury. The 31 mm Oyster case is both technically and aesthetically refined: its screw-down caseback and Twinlock double-waterproofness crown deliver 100 metres of water resistance, while the scratch-resistant sapphire crystal with integrated Cyclops lens magnifies the date aperture at 3 o'clock for effortless legibility.

The defining feature of reference 278384RBR is its 18-carat white gold bezel set with 46 brilliant-cut diamonds, each hand-selected for cut, clarity, and brilliance. Against this sparkling frame, the white dial carries crisp Roman numeral hour markers that reinforce the piece's classical disposition. The combination of diamond-set bezel and clean white lacquer dial creates a dialogue between gemological opulence and horological restraint — a balance that defines the Datejust's enduring appeal across decades of design evolution.

At the heart of the watch beats Rolex's Calibre 2236, a manufacture movement developed specifically for the 31 mm case family. Oscillating at 28,800 vph with a Syloxi silicon hairspring for superior resistance to magnetic fields and temperature fluctuation, the 2236 delivers a certified chronometer standard of precision alongside approximately 55 hours of power reserve. The Oystersteel Oyster bracelet with its flat three-piece links and concealed Oysterclasp ensures a secure, polished fit that completes this thoroughly accomplished timepiece.
