The Rolex Datejust 31 reference 278343RBR-0004 is a mid-size luxury timepiece that combines a 31mm Oystersteel case with an 18k yellow gold domed bezel set with 24 diamonds. This model features a sunray silver dial characterized by yellow gold Roman numeral hour markers and a distinctive large VI set with 11 diamonds. The watch is presented on a two-tone Yellow Rolesor Jubilee bracelet, which features five-piece links and a concealed folding Crownclasp for a seamless aesthetic.
At the heart of the timepiece is the Manufacture Rolex caliber 2236, a self-winding mechanical movement that offers a power reserve of approximately 55 hours. The movement is a COSC-certified Superlative Chronometer, ensuring high precision with a tolerance of -2/+2 seconds per day. Complications include central hours, minutes, and seconds, along with an instantaneous date window at the 3 o’clock position magnified by a Cyclops lens. The watch is engineered for durability with a scratch-resistant sapphire crystal and a Twinlock double waterproofness system, providing water resistance up to 100 meters.
General reviews of the Datejust 31 collection emphasize its versatility and classic design, noting that the 31mm size offers a balanced alternative to smaller lady’s models. The “scattered” or star diamond bezel is often highlighted as a playful and elegant variation of traditional gem-setting, providing luxury without the full saturation of a standard diamond bezel. Collectors and enthusiasts appreciate the model for its reliable movement and the enduring value associated with the Rolesor construction. While the Jubilee bracelet is praised for its comfort and supple feel, some note that the high-polish center links and gold bezel require careful maintenance to avoid visible scratches over time.
