Rolex Day-Date 36 White Gold — Black Diamond Dial, Fluted Bezel | Ref. 118239

Reference 118239 is a Day-Date 36 in 18ct white gold with a fluted bezel and a black dial set with diamond hour markers — a combination of formal gravitas and subdued luxury that has distinguished the Day-Date since its Perpetual Calendar functions first appeared in 1956. White gold imparts a cooler, more contemporary look than the traditional yellow gold President, and the black dial with diamond indices creates striking contrast that reads clearly across a boardroom table or dinner setting.

Inside the 36mm Oyster case sits Calibre 3155, Rolex's self-winding movement designated for older Day-Date 36 production before the current 3255 was introduced. The 3155 features an instant-action day disc mechanism, a date display, and a bidirectional rotor winding system, running at 28,800 vph with a 48-hour power reserve. The President bracelet — exclusive to the Day-Date and available only in precious metal — features semi-circular three-piece links that conform naturally to the wrist and provide the watch's instantly recognisable profile.

White gold Day-Date references with diamond dials occupy a well-defined collector tier. The 118239 predates the current 128239 platform but shares the same essential brief: discreet presidential authority. Collectors who prioritise wearability over specification sheets will find the 36mm case suits a wider demographic than the larger 40mm Day-Date 40. Full set examples have historically held value well, and diamond-dial variants in white gold tend to appreciate more consistently than plain-dial counterparts in the pre-owned market.
