Rolex Datejust 31 18ct Yellow Gold & Diamonds — Red Ombré Diamond-Set Dial | Ref. 278278

Among the most expressive expressions of the Datejust 31 lineage, reference 278278 pairs an 18ct yellow gold and diamond-set case with a showstopping Red Ombré dial whose stones graduate from deep crimson at the centre to a lighter blush at the chapter ring. The combination of the iconic fluted bezel — itself crafted in yellow gold — and the fully jewelled dial elevates this piece well beyond conventional dress watch territory into wearable jewellery of the highest order.

At its heart beats Calibre 2236, Rolex's in-house movement developed specifically for the brand's 31mm ladies' references. The silicon Syloxi hairspring offers exceptional resistance to magnetic fields and thermal variation, while the Parachrom system contributes to a 55-hour power reserve. The 18ct yellow gold bracelet — President or Jubilee depending on configuration — is finished to exacting tolerances, with each link polished and brushed by hand. The case is rated waterproof to 100 metres, underpinned by the Twinlock crown system.

This reference appeals to collectors who regard their timepiece as a complete jewellery statement rather than simply a watch. The Red Ombré dial, introduced in Rolex's more recent gem-setting programmes, commands a premium over standard dials and tends to retain strong resale value. Presented in like-new condition with original box and papers, this example represents an outstanding acquisition for a buyer seeking maximum presence in a 31mm footprint.
