The Rolex Datejust 31 reference 278241-0002 is a mid-size luxury timepiece that combines a 31mm Oystersteel case with an 18k Everose gold domed bezel. This distinctive blend of metals, known as Everose Rolesor, extends to the five-piece link Jubilee bracelet, which is secured by a concealed folding Crownclasp. The watch features a crisp white dial adorned with 18k pink gold Roman numeral hour markers and a date window at the 3 o’clock position, magnified by the signature Cyclops lens on the scratch-resistant sapphire crystal.
At its core, the timepiece is powered by the Rolex Caliber 2236, a self-winding mechanical movement that is a COSC-certified Superlative Chronometer. This movement utilizes a patented Syloxi hairspring in silicon and high-performance Paraflex shock absorbers to ensure a precision of -2/+2 seconds per day and a power reserve of approximately 55 hours. Designed for durability and daily wear, the Oyster architecture includes a monobloc middle case, a screw-down case back, and a Twinlock double waterproofness system, providing water resistance up to 100 meters.
General reviews of the Datejust 31 often emphasize its versatile aesthetic, noting that the combination of steel and rose gold creates a balanced look that is both sporty and dressy. The 31mm size is frequently praised for its comfortable proportions on smaller wrists, sitting flat and conforming well to the wrist shape. Users often highlight the Jubilee bracelet for its exceptional suppleness and long-term comfort, while the white Roman dial is recognized for its classic, highly legible design that remains a staple of the Datejust collection’s enduring appeal.
