Rolex Steel and Yellow Gold Datejust 31 Watch - Diamond Bezel - Silver Diamond Roman Six Dial - Oyster Bracelet - 278383RBR sdr6o

Beneath the diamond-set bezel of the Rolex Datejust 278383RBR beats the caliber 2236, a self-winding movement that represents Rolex's latest generation of precision timekeeping with its paramagnetic blue Parachrom hairspring and extended 55-hour power reserve. This 31mm yellow gold case pairs with the distinctive silver diamond Roman six dial, where a single diamond marker replaces the traditional Roman numeral at six o'clock, creating an asymmetrical focal point that distinguishes this reference from standard Roman configurations. The two-tone construction combines Oystersteel with 18ct yellow gold, while the Oyster bracelet maintains the collection's tool-watch DNA despite the precious metal appointments.
