Rolex Datejust 28 Yellow Rolesor — Champagne Diamond Dial, Fluted Bezel | Ref. 279173

Reference 279173 brings the contemporary Datejust 28 generation's technical advances to a classic Rolesor aesthetic. The fluted bezel — cast in 18 ct yellow gold and machined to Rolex's precise serration standards — defines the watch's visual character, framing a champagne diamond dial that carries applied markers and set stones with equal refinement. Yellow Rolesor, combining Oystersteel with 18 ct yellow gold components, delivers a two-tone effect that has attracted Datejust buyers for decades, offering luxury warmth at a more accessible price point than a full gold configuration.

At the core of the 279xxx series is Calibre 2236, Rolex's current-generation movement designed specifically for the 28 and 31 mm Datejust. The 2236 is notable for its Syloxi hairspring — a silicon component developed and manufactured by Rolex — which provides superior resistance to magnetic fields, temperature variation, and gravitational position errors compared to traditional metallic hairsprings. Combined with the Perpetual self-winding rotor and a Parachrom-independent shock absorber system, the calibre achieves chronometer certification with a power reserve of approximately 55 hours.

For buyers seeking a smaller Datejust that combines wearability with jewellery-calibre finishing, reference 279173 represents a mature and well-rounded proposition. The Jubilee bracelet — standard on this reference — provides five-link flexibility and a dressy articulation that complements the fluted bezel and diamond dial without competing for visual attention. Full-set examples of current-generation Datejust 28 references in Rolesor retain strong secondary market values, driven by their combination of factory gem-work, precious metal content, and Rolex's Certified Pre-Owned programme eligibility.
