Rolex Datejust 28 Everose Rolesor — Diamond Bezel Aubergine Diamond Dial | Ref. 279381RBR

Reference 279381RBR occupies a distinctive niche in the Lady-Datejust 28 range, pairing an Everose Rolesor case with a diamond-set bezel and an aubergine diamond dial. The aubergine colour — a deep, warm purple with brown undertones — is among the rarer dial options in the Datejust 28 catalogue, chosen by Rolex to complement the rose gold warmth of the Everose components. Diamond hour markers replace the standard applied indices, and the overall effect is of a watch conceived as much as a jewelled object as a precision instrument.

Calibre 2236 powers this reference, bringing Rolex's current-generation silicon Syloxi hairspring technology to the 28mm platform. The movement's COSC-certified accuracy, combined with resistance to magnetic fields courtesy of the silicon components, provides a level of technical reliability that matches the decorative ambition of the case and dial. The diamond bezel is set with brilliant-cut diamonds in a channel setting, and the Everose gold crown provides the means to set the date and time without disturbing the watch's water resistance, rated to 100 metres.

The 279381RBR is an uncommon find on the secondary market, as aubergine dials in any Datejust size have historically been produced in limited quantities. Buyers seeking this specific combination — Everose Rolesor, diamond bezel, aubergine ground, diamond markers — should expect to exercise patience in sourcing an example in excellent condition. The depth of the aubergine colour can appear to shift under different lighting conditions, ranging from near-purple in direct light to a rich, brownish plum in shade, which experienced collectors regard as one of the reference's most compelling characteristics.
