The Rolex Datejust 31 reference 278341RBR-0015 is a luxury women’s timepiece that harmoniously blends Oystersteel and 18k Everose gold, a combination known as Everose Rolesor. The 31mm case features a domed bezel meticulously set with diamonds, housing a silver dial with a sunray finish. This dial is further elevated by ten diamonds set in 18k gold settings, which serve as hour markers, and the signature Cyclops lens positioned over the date window at 3 o’clock for enhanced legibility. It is paired with a robust three-piece link Oyster bracelet that includes an Oysterclasp and the Easylink 5mm comfort extension system.
Internally, the watch is powered by the manufacture caliber 2236, a self-winding mechanical movement that is a certified Superlative Chronometer, ensuring a precision of -2/+2 seconds per day. This movement features a Syloxi hairspring in silicon and high-performance Paraflex shock absorbers, providing a power reserve of approximately 55 hours. The timepiece is designed for everyday resilience, featuring a scratch-resistant sapphire crystal and a Twinlock screw-down crown that contributes to a water resistance rating of 100 meters.
General reviews of the Datejust 31 collection emphasize its status as a versatile and timeless investment piece. Collectors and critics often highlight the model’s balanced proportions, noting that the 31mm size offers a sophisticated presence that is substantial yet remains elegant on smaller wrists. The Everose Rolesor finish is frequently praised for its warm, contemporary aesthetic compared to traditional yellow gold, while the combination of a diamond-set bezel and dial is regarded as a classic expression of Rolex’s jewelry-making expertise. Owners appreciate its ability to transition seamlessly from formal occasions to daily wear, though some note the premium price point associated with its extensive gem-setting.
