The Rolex Datejust 31 reference 278344RBR-0029 is an elegant mid-size luxury timepiece featuring a 31mm White Rolesor case, which combines a durable Oystersteel middle case with an 18k white gold bezel. This specific model is distinguished by its dark grey rhodium dial with a sunray finish, adorned with polished 18k white gold Roman numerals and a signature large VI set with 11 diamonds. The fixed domed bezel is further enhanced by 24 scattered diamonds, creating a distinctive star-like aesthetic. It is fitted with a three-piece link Oyster bracelet crafted from Oystersteel, featuring a folding Oysterclasp and the Easylink 5mm comfort extension system for easy adjustments.
The watch is powered by the caliber 2236, a self-winding mechanical movement manufactured by Rolex that offers a power reserve of approximately 55 hours. This movement is a Superlative Chronometer, ensuring precision of -2/+2 seconds per day. Its primary complications include center hour, minute, and seconds hands, along with an instantaneous date window at 3 o’clock magnified by the iconic Cyclops lens. Designed for reliability, the Oyster case utilizes a Twinlock double waterproofness system and a scratch-resistant sapphire crystal, providing water resistance up to 100 meters.
General reviews of the Datejust 31 collection emphasize its versatile sizing, which appeals to those seeking a balance between the smaller Lady-Datejust and the larger 36mm models. The reference 278344RBR is frequently praised for its sophisticated blend of materials and the subtle brilliance of its scattered diamond bezel, which offers a more modern alternative to traditional fully set bezels. While it is highly regarded for its robust construction and timeless design, some enthusiasts note that the 31mm size may feel delicate on larger wrists and that the high-polish center links of the Oyster bracelet can be prone to visible scratches over time.
