The Rolex Datejust 31 reference 278271-0028 is a luxury timepiece that combines professional-grade engineering with elegant aesthetics. It features a 31mm Everose Rolesor case, which is a signature Rolex marriage of corrosion-resistant Oystersteel and 18k Everose gold. The watch is defined by its sunray-finish chocolate dial, adorned with ten factory-set diamond hour markers in 18k gold settings. This model is equipped with a bidirectional rotatable fluted bezel in Everose gold and is paired with a five-piece link Jubilee bracelet featuring a concealed folding Crownclasp.
Technically, the watch is powered by the manufacture caliber 2236, a self-winding mechanical movement that incorporates a patented Syloxi hairspring in silicon for superior resistance to magnetic fields and temperature variations. This COSC-certified chronometer offers a power reserve of approximately 55 hours and maintains a precision of -2/+2 seconds per day. The Oyster case architecture, featuring a screw-down Twinlock winding crown and a scratch-resistant sapphire crystal with a Cyclops lens, ensures water resistance to a depth of 100 meters. The primary complications include instantaneous date adjustment with a rapid-setting function and stop-seconds for precise time synchronization.
General reviews of the Datejust 31 often highlight its ideal proportions for a mid-size luxury watch, bridging the gap between traditional ladies’ models and larger contemporary sizes. Collectors frequently praise the warmth of the chocolate dial paired with the proprietary Everose gold alloy, noting that it provides a more modern and subtle alternative to traditional yellow gold. While the aesthetic is widely celebrated for its versatility, some critical feedback notes that the concealed clasp on the Jubilee bracelet lacks the micro-adjustment features found on Oysterlock clasps, though it is often preferred for its seamless and jewelry-like appearance.
