Rolex Lady-Datejust 28 White Rolesor — Dark Grey Index Fluted Bezel Dial | Ref. 279174

Reference 279174 is a Lady-Datejust 28 in White Rolesor, defined by its dark grey dial fitted with applied index hour markers and paired with an 18 ct white gold fluted bezel. The dark grey dial is a relatively uncommon choice in the Lady-Datejust range, where lighter and warmer tones dominate. Its cooler, more contemporary character gives this reference a unisex visual weight unusual for a 28 mm watch and broadens its appeal beyond the purely feminine demographic for which Rolex originally sized the case. The fluted bezel's vertical grooves catch light distinctively, framing the dial with geometric precision.

The Calibre 2236 powers this reference, a self-winding movement Rolex introduced specifically for the Lady-Datejust and Pearlmaster families. The 2236 incorporates a silicon Syloxi hairspring — Rolex's in-house development offering superior resistance to temperature variation, magnetism, and shock compared to traditional alloy springs — alongside a bidirectional Perpetual rotor and a power reserve of approximately 55 hours. The White Rolesor case combines stainless steel with 18 ct white gold on the bezel, crown, and corresponding bracelet components, providing a durable and bright two-tone aesthetic. Water resistance is rated to 100 metres.

On the secondary market, the 279174 in dark grey occupies a niche position — its restrained palette contrasts with the more common pink, silver, and champagne iterations, which makes it attractive to buyers seeking something understated within the Lady-Datejust lineup. Its Calibre 2236 with silicon hairspring represents a meaningful mechanical upgrade over older Lady-Datejust movements, and this factor increasingly influences informed buyers who prioritize long-term reliability over purely aesthetic considerations.
