Rolex Datejust 31 Yellow Gold — Champagne Diamond Dial, Diamond Bezel | Ref. 278288RBR (2)

Among Rolex's most celebrated mid-size expressions, the Datejust 31 in 18-karat yellow gold occupies a singular position at the intersection of gem-setting artistry and mechanical precision. Reference 278288RBR presents a 31 mm Oyster case whose bezel is pavé-set with 46 round brilliant diamonds — a scintillating surround that frames the champagne dial adorned with ten additional diamond hour markers. Every facet of the exterior reflects Rolex's lapidary mastery, while the deep warmth of yellow gold lends the piece an unmistakably regal character.

At its heart beats Calibre 2236, Rolex's manufacture movement developed specifically for the Lady and mid-size Datejust lines. The self-winding oscillator incorporates a Syloxi silicon hairspring — impervious to magnetic fields and changes in temperature — delivering a power reserve of approximately 55 hours alongside stop-seconds for setting accuracy to the second. The instantaneous date mechanism snaps cleanly at midnight, rendering the date window beneath the Cyclops magnification lens perfectly legible at a glance.

The President bracelet, exclusive to Rolex's most distinguished references, completes the composition with its distinctive semi-circular three-piece links in 18-karat yellow gold. Secured by the concealed Crownclasp, it drapes the wrist in understated opulence. Water-resistant to 100 metres via the screw-down Twinlock crown, the 278288RBR is equally at home at a formal dinner or a sun-drenched terrace — a testament to Rolex's ability to fuse jewellery-grade elegance with sport-watch robustness.
