The Rolex Datejust 31 reference 278343RBR-0003 is a mid-size luxury timepiece that combines professional-grade engineering with high-jewelry aesthetics. The 31mm Oyster case is constructed from Yellow Rolesor, a signature Rolex marriage of corrosion-resistant Oystersteel and 18k yellow gold. This model is distinguished by its silver sunray dial, which features a mix of yellow gold Roman numeral hour markers and a prominent large VI at the 6 o’clock position set with 11 diamonds. A significant design highlight is the domed yellow gold bezel, which features a scattered diamond pattern of 24 stones that provides a playful and unique visual texture.
Technically, the watch is powered by the manufacture caliber 2236, a self-winding mechanical movement equipped with a patented Syloxi hairspring in silicon for superior resistance to magnetic fields and temperature variations. This movement provides a power reserve of approximately 55 hours and is a certified Superlative Chronometer, ensuring precision within -2/+2 seconds per day. Complications are focused on essential utility, featuring 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 depth-rated to 100 meters, aided by a Twinlock double waterproofness system and a screw-down winding crown.
General reviews of this specific Datejust iteration frequently emphasize its versatility and “playful elegance.” While the 31mm size is traditionally marketed for women, the modern proportions and robust Yellow Rolesor construction make it a popular choice for those seeking a sophisticated daily wearer. The Oyster bracelet, featuring three-piece flat links and an Easylink 5mm comfort extension, is praised for its durability and secure fit compared to the dressier Jubilee alternative. Critics and owners alike often highlight the scattered diamond bezel as a standout feature that differentiates it from standard fluted or smooth bezel models, though some note that the lack of double anti-reflective coating on the sapphire crystal can occasionally affect legibility in direct light.
