The Rolex Datejust 31 reference 278343RBR-0025 is a luxury timepiece that combines durability with high-end materials, featuring a 31mm case crafted from Yellow Rolesor, which is a signature blend of Oystersteel and 18k yellow gold. The watch is defined by its champagne-color dial adorned with diamond hour markers in 18k gold settings and a domed 18k yellow gold bezel set with 24 diamonds. It is equipped with a scratch-resistant sapphire crystal and a Cyclops lens over the date window at 3 o’clock. The construction includes a monobloc middle case, a screw-down case back, and a Twinlock winding crown, ensuring water resistance up to 100 meters. It is paired with a three-piece link Oyster bracelet featuring a folding Oysterclasp and the Easylink 5mm comfort extension system.
The timepiece is powered by the manufacture caliber 2236, a self-winding mechanical movement that provides a power reserve of approximately 55 hours. This movement is a Superlative Chronometer, certified for precision with a rating of -2/+2 seconds per day. Its complications include central hour, minute, and seconds hands, an instantaneous date with rapid setting, and stop-seconds for precise time adjustment. The movement also features a Syloxi hairspring in silicon and high-performance Paraflex shock absorbers to maintain accuracy and stability under various conditions.
General reviews of the Datejust 31 often praise its balanced proportions, which serve as a versatile mid-size option for those seeking a presence that is neither too large nor too dainty. The combination of the champagne dial and the “scattered” diamond bezel is frequently highlighted for its elegant yet playful aesthetic, offering a distinctive alternative to traditional full-diamond bezels. While the watch is celebrated for its legendary design and robust build quality, some collectors note that the 31mm size and gem-setting lean toward a more jewelry-oriented style compared to the larger professional models. Critics and enthusiasts alike regard it as a premier luxury dress watch that maintains the functional reliability expected from the Rolex Oyster Perpetual line.
