Rolex Day-Date 40 18 ct Everose Gold & Diamonds — White MOP Diamond Dial | Ref. 228345RBR

Few timepieces command attention quite like the Day-Date 40 reference 228345RBR, an apotheosis of gem-set haute horlogerie that sees Rolex's proprietary 18 ct Everose gold — an exclusive rose-gold alloy formulated never to fade — adorned with a bezel set entirely with brilliant-cut diamonds. The 40 mm Oyster case carries a white mother-of-pearl dial set with diamond hour indicators, creating a scintillating interplay of light that affirms this watch's position at the very pinnacle of the Day-Date collection.

The Calibre 3255 powering this reference is a statement of manufacture mastery. Its 14 patents encompass the barrel, escapement, balance wheel and balance spring, collectively providing a 70-hour power reserve with exceptional resistance to shocks and magnetic fields. The Parachrom hairspring, produced from a proprietary paramagnetic alloy, is up to ten times more resilient to magnetic disturbance than conventional hairsprings. Chronometric performance is rated at ±2 seconds per day under SCSC certification — a benchmark that far surpasses industry norms. The President bracelet in matching 18 ct Everose gold ensures ergonomic comfort alongside aesthetic coherence.

Presented with original box and papers for 2024, reference 228345RBR occupies a rarefied position in the Rolex catalogue — one of relatively few configurations that combines the full-diamond bezel with a gem-set MOP dial in the warm rose tonality of Everose gold. For collectors assembling a definitive modern Rolex holding or seeking a landmark jewellery watch with genuine horological credentials, this Day-Date 40 is an exceptional and virtually irreplaceable example.
