Rolex Datejust 31 Yellow Rolesor — 46-Diamond Bezel White Roman Dial | Ref. 178383

The Datejust 31 in reference 178383 exemplifies the Rolesor philosophy — Rolex's proprietary combination of Oystersteel and 18 ct yellow gold — applied with gemological rigour. The bezel is set with 46 round brilliant-cut diamonds, hand-selected for colour and clarity, mounted in a grain-setting that allows each stone maximum exposure to incident light. This diamond-set surround elevates the 31 mm Oyster case beyond the merely decorative; every facet is an element of a unified aesthetic programme curated by Rolex's in-house jewellery ateliers. The Oyster case itself, machined from a solid block of material, retains its exemplary water resistance of 100 metres.

The white lacquer dial with Roman numeral hour indices achieves a clarity that reads as both classical and contemporary. Roman numerals in 18 ct yellow gold impart a dress-watch sensibility, while the date window at three o'clock — magnified 2.5 times by the Cyclops lens — maintains the Datejust's defining identity since 1945. Powering the display is the self-winding Calibre 2236, Rolex's dedicated ladies' movement featuring the Syloxi silicon hairspring, whose paramagnetic properties and insensitivity to temperature fluctuations set a new benchmark for precision in this movement class. Power reserve stands at approximately 55 hours.

The Jubilee bracelet in Yellow Rolesor — five-link, with polished centre links flanked by satin-finished outer links — was designed by Hans Wilsdorf himself to accompany the inaugural Datejust in 1945 and remains the bracelet most intimately associated with the model. Secured by the folding Crownclasp, the bracelet provides a considered balance of elegance and wearability on the 31 mm wrist, making the 178383 an accomplished dresser of enduring appeal.
