Description
Powered by Rolex’s perpetual, self-winding caliber 2236 movement with a 55-hour power reserve, this Datejust 278383RBR combines the precision engineering collectors expect with the striking visual drama of a dark mother-of-pearl diamond dial set within a 31mm yellow gold case. The diamond-set bezel creates a brilliant frame that amplifies the natural iridescence of the dark nacre, while the robust Oyster bracelet maintains the collection’s utilitarian DNA despite the elevated precious metal construction. This unworn example represents the modern evolution of the Datejust’s mid-size category, bridging sports watch functionality with jewelry-grade finishing.
