Rolex Datejust Yellow Gold — Fluted Bezel Silver Index Dial | Ref. 279178

Reference 279178 is the solid-yellow-gold specification of the Lady-Datejust 28, combining an 18-carat yellow gold Oyster case with Rolex's iconic fluted bezel — machined in-house from the same yellow gold as the case — and a silver dial carrying applied index hour markers. This configuration is the purest precious-metal expression of the Lady-Datejust's original character: no diamonds, no two-tone Rolesor, just the interplay of polished and satin-brushed yellow gold surfaces against a clean silver dial. The President bracelet in yellow gold seals the ensemble.

Powering the 279178 is Calibre 2236, the movement Rolex developed specifically for the 28 mm and 31 mm Datejust case families. Its Syloxi silicon hairspring — produced in-house using photolithographic etching — provides superior magnetic resistance and thermal stability compared to conventional paramagnetic alloys. The Perpetual bidirectional winding rotor and 55-hour power reserve ensure reliable timekeeping across extended periods without wear. Water resistance of 100 metres is delivered via the screw-down Twinlock crown, a specification that significantly outperforms most comparable dress-watch competitors.

A solid yellow gold Lady-Datejust with a plain silver index dial is perhaps the most classically correct configuration in the current 28 mm range. It avoids the sometimes polarising aesthetics of diamond settings while remaining unambiguously precious in material composition. For collectors who value discretion and long-term wearability over immediate visual impact, the 279178 offers an enduring choice — one that tracks closely to historical Datejust design decisions while incorporating three generations of movement refinement.
