About this watch

The Rolex Datejust 31 is a stunning luxury timepiece that embodies the spirit of Rolex. With its elegant design and high-tech movement, this watch is perfect for both everyday wear and special occasions. The black dial with Roman numerals exudes classic elegance, while the glossy finish adds a touch of modern sophistication. Crafted from stainless steel, the case has a solid feel that speaks to the watch's durability and longevity. At the heart of the Datejust 31 lies the Rolex caliber 2236, a self-winding mechanical movement that represents a new generation of Rolex movements. With a power reserve of 55 hours, you can count on it to keep time accurately even when you take it off at night. The frequency of 28,800 vibrations per hour ensures smooth operation of the seconds hand, adding to the watch's overall charm. What truly sets the caliber 2236 apart is its innovative Syloxi hairspring, made from silicon, which enhances the watch’s resistance to shocks and magnetic fields. The Datejust 31 offers a straightforward yet effective display with hands indicating hours, minutes, and seconds, making it easy to read time. With a water resistance of 100 meters, this watch is not just a pretty face; it’s built for adventure. Whether you're caught in the rain or taking a dip in the pool, you can trust that your Datejust 31 will withstand the elements.
