The Rolex Datejust 31 reference 278243-0001 is a refined luxury timepiece featuring a 31mm case crafted from Yellow Rolesor, a signature Rolex combination of 904L Oystersteel and 18k yellow gold. This model is characterized by its crisp white lacquer dial adorned with yellow gold Roman numeral hour markers and the iconic Cyclops lens positioned over the date window at 3 o’clock. The case is equipped with a smooth, domed 18k yellow gold bezel and a Twinlock screw-down crown, ensuring water resistance up to 100 meters.
Inside, the watch is powered by the COSC-certified caliber 2236, a self-winding mechanical movement entirely manufactured by Rolex. This movement incorporates a Syloxi hairspring in silicon and high-performance Paraflex shock absorbers to provide superior resistance to magnetic fields and environmental variations. It offers a power reserve of approximately 55 hours and maintains a precision of -2/+2 seconds per day. The timepiece is completed with a three-piece link Oyster bracelet in Yellow Rolesor, featuring a folding Oysterclasp and the Easylink 5mm comfort extension link for easy size adjustments.
General reviews of the Datejust 31 highlight its versatility as a mid-size luxury watch that balances classic elegance with modern technical reliability. Users frequently praise the timeless appeal of the white Roman dial and the durability of the Rolesor construction, making it suitable for both formal and daily wear. While some collectors note that the 31mm size is traditionally marketed towards women, it is often reviewed as a well-proportioned option for any wearer seeking a more understated, historical silhouette. Minor critiques sometimes focus on the high demand and market pricing typical of the Datejust collection.
