Ref. 228398TBR-0041
Rolex Day-Date 40, reference 228398TBR-0041, cased in 40 mm of 18 ct yellow gold. The case measures 12 mm thick and pairs with a diamond-set bezel, a combination that defines this reference. A Cyclops lens sits over the date on the scratch-resistant sapphire crystal. The bright black dial shows luminous hands and indices, and the movement is the calibre 3255, a self-winding, mechanically driven Superlative Chronometer with roughly 70 hours of power reserve. Beyond the day and date functions, the watch runs a central seconds display and is set with diamonds on the bezel. It is fitted to a President bracelet in yellow gold, closed by a concealed folding Crownclasp. The screw-down crown helps keep the case rated to 100 metres.
