Rolex Datejust 28 Yellow Rolesor — Mint Green Diamond Dial | Ref. 279383RBR

The Lady-Datejust 28 in reference 279383RBR combines Yellow Rolesor construction with a diamond-set bezel and a mint green dial set with diamond hour markers — a configuration that aligns colour and material with a level of intentionality rarely seen outside dedicated jewellery workshops. Mint green is among the more distinctive dial colours available in the current Lady-Datejust range, carrying enough chromatic individuality to serve as a conversation piece while still pairing naturally with gold and warm-toned settings.

Calibre 2236 powers this 28 mm reference, a movement purpose-built for Rolex's ladies' size case and featuring the silicon Syloxi hairspring for improved resistance to both magnetic fields and temperature fluctuation. The 55-hour power reserve exceeds what was available in the prior generation, and the certified chronometer precision is identical to that of any larger Rolex movement. The Yellow Rolesor case blends Oystersteel with 18ct yellow gold on the bezel, winding crown, and bracelet centre links, with the RBR diamond bezel adding further density of precious material.

Buyers for this reference are typically drawn to the mint green and diamond pairing specifically — it is not a neutral purchase. The colour has attracted sustained interest since its introduction, and Yellow Rolesor examples retain it better than white gold alternatives because the warmth of yellow gold balances the cool green of the dial. Pre-owned values are well-supported, particularly for examples in excellent condition with original bracelet and clasp. Full set with box and papers is the expectation at this price point, and any modification to the bracelet or bezel setting should be disclosed and factored into pricing.
