About This Watch

The Rolex Datejust 31 in yellow gold embodies the quiet elegance of a timepiece that balances tradition with contemporary refinement. This iteration, distinguished by its olive dial and gem-set indexes, marries the brand’s storied heritage with a striking, understated palette. The fluted bezel, a hallmark of the Datejust collection since its introduction in 1945, frames the dial with a sense of timeless gravitas, while the sunburst finish on the olive dial adds depth and movement under light. The stick hands and diamond-set hour markers further enhance its legibility and sophistication, ensuring the watch remains both functional and visually arresting. At its core, the Datejust 31 is powered by Rolex’s in-house 2236 automatic movement, a testament to the brand’s commitment to precision engineering. This calibre, with its Parachrom balance spring and blue Paraflex shock absorbers, ensures exceptional accuracy and resilience, while the date display operates seamlessly through the sapphire crystal. The case, crafted from 18ct yellow gold, is both durable and lustrous, complemented by a water resistance
