Rolex Lady-Datejust 28 Everose Rolesor — Chocolate Roman | Ref. 279171

Rolesor — Rolex's term for a combination of Oystersteel and gold — has been a defining feature of the Datejust since the 1930s, and Reference 279171 presents it in the Everose formulation that has become a house signature since its introduction in the early 2000s. Everose gold is a proprietary 18 ct rose gold alloy in which platinum is incorporated to stabilise the colour over time, preventing the fade that can affect conventional rose gold alloys. The result is a warmth of tone that remains consistent through decades of wear — a meaningful guarantee on a watch intended to be kept and passed on.

The 28 mm case dimension of the Lady-Datejust places this reference within the smaller format that Rolex calibrates specifically for a feminine market, though the specification is identical in its rigour to larger counterparts. The fluted bezel in Everose gold introduces the collection's most recognisable decorative element — a motif that originated as a functional knurling to facilitate case opening and evolved into a Datejust signature of enduring appeal. The chocolate dial with Roman numeral hour markers in white gold presents a warm, harmonious composition that acknowledges prevailing trends toward earth-toned dials without sacrificing legibility.

Calibre 2236 powers this reference, a movement developed specifically by Rolex for the Lady-Datejust and Pearlmaster families. Its most notable technical contribution is the Syloxi hairspring, a silicon-based oscillator conceived in-house that combines the paramagnetic properties of silicon — negligible sensitivity to magnetic fields — with a geometry optimised for consistent isochronism. At 55 hours of power reserve, the 2236 provides adequate autonomy for the weekend, and its Paraflex shock absorbers ensure resilience against the impacts of everyday life.
