Rolex Datejust 31 Yellow Rolesor — White Diamond Dial | Ref. 178383

Reference 178383 represents the Datejust 31 in its most resplendent Yellow Rolesor configuration — a combination of Oystersteel and 18ct yellow gold that has defined mid-size Rolex dress watchmaking for decades. The 46-diamond bezel frames a white dial set entirely with brilliant-cut diamonds in place of hour indices, creating a dial surface that glitters with every movement of the wrist. At 31mm, the case occupies a versatile position between the Lady-Datejust 28 and the Datejust 36, appealing to collectors who prefer a slightly more substantial presence without sacrificing elegance.

Powering the watch is Rolex's Calibre 2236, a manufacture movement developed specifically for mid-size and ladies' references. Its centrepiece is the Syloxi hairspring — a silicon component with superior resistance to magnetic fields and temperature variation — delivering a 55-hour power reserve. The Rolesor case pairs an Oystersteel case body with yellow gold crown, bezel setting, and bracelet centre links, a pairing Rolex has refined since the 1930s. The Oyster bracelet provides robust water resistance to 100 metres courtesy of the Twinlock crown system.

For collectors, the 178xxx generation represents the final iteration before Rolex migrated the 31mm series to the 278xxx reference family with updated lugs and enhanced movement. Diamond-dial Rolesor examples in this reference command strong secondary-market interest, particularly among buyers seeking a fully jewelled dress watch that retains Rolex's hallmark tool-watch durability. The combination of factory diamond indices and a diamond bezel makes this an exceptionally complete jewellery timepiece from the Oyster Perpetual stable.
