Rolex Datejust 28 Gold — Aubergine Diamond Dial with 44-Diamond Bezel | Ref. 279135RBR

Reference 279135RBR distils the Lady-Datejust's jewellery credentials into their most luxurious expression: a 28mm case in 18ct gold, a factory 44-diamond bezel, and an aubergine dial set entirely with diamonds in place of conventional hour markers. Aubergine — a deep, warm purple with brown undertones — is among the most distinctive dial colours in the Datejust palette, exuding a richness that is simultaneously bold and refined.

Calibre 2236, Rolex's manufacture movement for the 26–31mm case family, provides the mechanical foundation. Its Syloxi silicon hairspring in a free-sprung balance ensures exceptional resistance to shocks, temperature variation, and magnetic interference, all within a movement certified to COSC chronometer tolerances. The 55-hour power reserve exceeds what might be expected of a watch in this size class. The case itself, fully finished in gold with the Oyster architecture's characteristic integration of crown guards and screw-down caseback, delivers 100 metres of water resistance — a practical commitment that speaks to Rolex's insistence on robustness even in its most ornate pieces.

For the collector, the 279135RBR in aubergine with diamond dial and 44-stone bezel is a rare configuration. Factory gem-set references at this level carry significant premiums over standard-dial equivalents, and the aubergine dial colour occupies a niche within the range that appeals to buyers who prioritise distinctiveness. This is a watch suited to formal occasions and significant events — a jewelled timepiece that wears its horological seriousness quietly beneath its considerable decorative presence.
