The Rolex Datejust 31 reference 278271-0001 is a mid-size luxury timepiece that combines professional-grade Oystersteel with 18k Everose gold, a combination known as Everose Rolesor. This model features a 31mm case equipped with a screw-down Twinlock crown and a solid case back, ensuring water resistance up to 100 meters. The aesthetic is defined by a polished fluted bezel and a white dial adorned with 18k Everose gold Roman numeral hour markers. The watch is paired with a three-piece solid link Oyster bracelet that includes a folding Oysterclasp and the Easylink 5mm comfort extension link for minor adjustments.
Internally, the timepiece is powered by the manufacture Rolex caliber 2236, a self-winding mechanical movement that utilizes a Syloxi hairspring in silicon to enhance resistance to shocks and temperature variations. This movement offers a power reserve of approximately 55 hours and provides the primary complications of center hour, minute, and seconds hands, alongside an instantaneous date display visible through the Cyclops lens at the 3 o’clock position. The movement is a certified Superlative Chronometer, meaning it has passed rigorous testing to ensure precision within -2/+2 seconds per day after casing.
General reviews of the Datejust 31 278271 often emphasize its balanced proportions, which serve as a versatile option for those who find the traditional 28mm Lady-Datejust too small and the 36mm version too large. The Everose Rolesor finish is frequently praised for its warm, contemporary hue compared to traditional yellow gold. While enthusiasts appreciate the robust caliber 2236 for its high-performance shock absorbers and magnetic resistance, some critics note that the mid-size luxury segment is highly competitive and point to the model’s high demand on the secondary market. However, it remains a foundational icon in the Rolex catalog for its blend of durability and timeless elegance.
