The Rolex Datejust 31 reference 278289RBR-0023 is a luxury mid-size timepiece characterized by its 31mm case crafted entirely from 18k white gold. This model is distinguished by a vibrant bright blue dial featuring a sunray finish and applied 18k white gold Roman numeral hour markers. The aesthetic is further enhanced by a fixed bezel meticulously set with 46 diamonds. It is paired with the prestigious President bracelet, which consists of semi-circular three-piece links and a concealed folding Crownclasp, a configuration traditionally reserved for Rolex’s precious metal models.
At the heart of the watch is the manufacture caliber 2236, a self-winding mechanical movement that incorporates a Syloxi hairspring in silicon for enhanced resistance to magnetic fields and temperature variations. This movement provides a power reserve of approximately 55 hours and carries the Superlative Chronometer certification, ensuring a precision of -2/+2 seconds per day after casing. The watch features essential complications including central hours, minutes, and seconds, along with an instantaneous date display at the 3 o’clock position, magnified by the iconic Cyclops lens on the scratch-resistant sapphire crystal.
General reviews of the Datejust 31 collection emphasize its versatility and balanced proportions, making it a popular choice for those seeking a modern yet classic feminine timepiece. The 278289RBR specifically is praised for its high-end material execution and the “regal” appearance of the white gold and diamond combination. While noted as a significant investment due to its full gold construction, the model is highly regarded for its reliability and 100-meter water resistance, allowing it to function effectively as a daily luxury watch. Minor critiques generally focus on the premium pricing associated with the gem-set precious metal references compared to stainless steel alternatives.
