Rolex Datejust 31 White Rolesor — White Index Dial, 46-Diamond Bezel | Ref. 178384

White Rolesor — the marriage of Oystersteel and 18-carat white gold first conceived by Rolex in the 1930s — reaches a considered peak in the Datejust 31 Ref. 178384. The 31 mm case pairs the metal's dual character with a bezel set with 46 diamonds, each individually clawed into 18-carat white gold to maximise brilliance across the entire circumference. Against the white dial and its applied index markers, this ring of diamonds frames the hours as if setting a stage.

Powering the reference is Calibre 2235, the self-winding manufacture movement Rolex engineered for the Datejust 31. Its Parachrom hairspring — blue by virtue of the oxidation treatment that enhances its anti-magnetic performance — beats at a comfortable 28,800 vph, and the bidirectional Perpetual rotor delivers consistent winding in both directions. The Cyclops lens, positioned over the date aperture at 3 o'clock, magnifies the numeral by 2.5x, a pragmatic detail that has become one of Rolex's most recognisable signatures.

The Jubilee bracelet — introduced alongside the original Datejust at the 1945 Geneva Watch Fair — links the watch's heritage to its present configuration with five-piece links whose alternating finishes echo the interplay of steel and gold throughout the case. Comfortable, proportioned, and intrinsically suited to the 31 mm Datejust, it closes with a concealed folding clasp. Water resistant and built to be worn daily, the Ref. 178384 is a quietly magnificent everyday companion.
