The Rolex Datejust 31 reference 278271-0026 is a luxury mid-size timepiece featuring a 31mm case crafted from Everose Rolesor, a signature combination of Oystersteel and 18kt Everose gold. This model is distinguished by its white mother-of-pearl dial, which is naturally unique and adorned with ten diamond hour markers set in 18kt gold. The case is equipped with a fluted Everose gold bezel and a scratch-resistant sapphire crystal featuring a Cyclops lens for date magnification. It is paired with a five-piece link Jubilee bracelet that utilizes a concealed folding Crownclasp for a seamless aesthetic.
Internally, the watch is powered by the manufacture caliber 2236, a self-winding mechanical movement that incorporates a patented Syloxi silicon hairspring for enhanced resistance to shocks and magnetic fields. This movement provides a power reserve of approximately 55 hours and is a certified Superlative Chronometer, ensuring precision within -2/+2 seconds per day. Complications are focused on practical daily utility, including central hours, minutes, and seconds, alongside an instantaneous date window at the 3 o’clock position with a rapid-setting feature. The Twinlock screw-down crown and Oyster architecture allow for a water resistance rating of 100 meters.
General reviews of the Datejust 31 emphasize its versatility as a mid-sized option that balances the elegance of the smaller lady models with the more modern presence of larger variants. Enthusiasts frequently praise the white mother-of-pearl dial for its luster and the warm contrast provided by the Everose gold elements. While the 31mm size is highly regarded for its refined proportions and comfort on the wrist, some collectors note that the specific mother-of-pearl and diamond configuration can be more difficult to source at retail due to high demand for these decorative variants. Critics generally find little fault with the technical performance, citing the caliber 2236 as a robust and highly reliable movement for everyday wear.
