Rolex Datejust White Rolesor — Purple Diamond Dial with 24-Diamond Bezel & Roman Numerals | Ref. 178344

The 178344 sits within the 31 mm Datejust range — a size that bridges the Lady-Datejust 28 and the standard 36 mm reference — and in this configuration, it represents one of the most jewel-forward expressions of the platform. White Rolesor combines an Oystersteel case with 18 ct white gold for the bezel and bracelet inserts, and here the bezel is set with 24 diamonds, replacing the fluted or smooth alternatives with a continuous ring of brilliance. The purple diamond dial adds further depth, with diamond Roman numeral markers at six and twelve providing asymmetric emphasis.

Calibre 2235 powers this reference — the predecessor to the current 2236 — a self-winding movement with Parachrom hairspring that delivers reliable timekeeping within COSC chronometer tolerances. The 31 mm Oyster case offers 100 metres of water resistance, and the Jubilee bracelet in Rolesor construction provides the articulation appropriate to a watch of this scale. Diamond bezels on Datejust references are factory-set with precision, ensuring consistent stone placement and secure settings that outlast many aftermarket alternatives.

Buyers drawn to fully jewelled Datejust configurations will find the 178344 compelling for its combination of purple dial drama and diamond-set bezel restraint — a pairing that is not available across every size or generation of the model. On the pre-owned market, condition of the diamond settings is a key valuation factor; stones that remain bright and properly seated command premiums. This reference suits collectors who wear watches as personal adornment as much as timekeeping instruments, and its 31 mm diameter wears comfortably on a wide range of wrist sizes.
