Rolex Datejust White Rolesor — 24-Diamond Bezel, Pink Roman Dial | Ref. 178344

Reference 178344 presents the Datejust 31 in White Rolesor — Oystersteel cases and bracelet elements combined with 18-carat white gold bezel, crown, and Jubilee bracelet centre links. The bezel is set with 24 individually mounted brilliant-cut diamonds, and the pink Roman dial introduces warm chromatic contrast against the cool white gold and steel architecture. Roman numeral hour markers in applied white gold are positioned at every hour, lending the dial a classical formality that traces directly to the original Datejust aesthetic of the 1940s.

Powering the 178344 is Calibre 2236, the manufacture movement Rolex developed for the 28 mm and 31 mm Datejust platforms. The 2236 incorporates the Syloxi hairspring — a silicon component machined to exacting tolerances — which confers excellent resistance to both magnetic fields and temperature-induced rate variation. A 55-hour power reserve, Paraflex shock absorbers, and a bidirectional Perpetual rotor complete the movement specification, with Superlative Chronometer certification ensuring -2/+2 seconds daily accuracy after casing.

The Jubilee bracelet on this reference follows the five-piece link construction first introduced with the Datejust in 1945, here with white gold centre links complementing the Oystersteel outer links. Reference 178344 has since been superseded by the updated 278344RBR architecture, which transitions to the Rolesor nomenclature with revised case finishing. Accordingly, 178344 examples represent the final iteration of the classic 31 mm Datejust form factor, an aspect that adds modest historical interest to an already elegant specification.
