About this watch
The Rolex Datejust 31 is a true masterpiece of horological artistry. Its design seamlessly blends modern aesthetics with classic elegance. The use of white gold and stainless steel gives it a lustrous finish that catches the eye without being overly flashy. With a diameter of 31.00 mm and a lug width of 16.00 mm, the Datejust 31 is perfectly sized for both everyday wear and special occasions. It strikes a balance between being substantial enough to command attention while remaining delicate on the wrist. One of the standout features of this watch is its Mother of Pearl (MOP) dial. This unique material adds a touch of sophistication and iridescence, making each watch truly one-of-a-kind. The dial captures light beautifully, reflecting various colors depending on the angle, much like a pearl glistening in sunlight. The gem-set indexes enhance the watch's luxurious feel. These precision-set diamonds are not only functional but also add a level of opulence that few watches can match. They sparkle subtly, ensuring that you always stand out, whether you’re in a boardroom or at a gala. At the core of the Rolex 278344rbr-0005 lies the Rolex caliber 2236. This self-winding mechanical movement is a testament to Rolex's commitment to precision and reliability. Introduced in 2014, the caliber 2236 represents a significant leap forward in watchmaking technology. It was the first Rolex movement to feature the Syloxi hairspring, made from silicon, offering improved accuracy and resistance to magnetic fields. This means you can wear your watch without worrying about it losing time! Every Rolex watch is a certified Swiss chronometer, a designation reserved for high-precision timepieces that pass rigorous tests set by the Swiss Official Chronometer Testing Institute (COSC). With a power reserve of 55 hours and a frequency of 28,800 beats per hour, the caliber 2236 is designed for those who demand the utmost in performance. With a water resistance rating of 100 meters, the Datejust 31 is more than just a pretty face. It’s equipped to handle splashes and brief immersions, making it suitable for daily activities, from washing your hands to diving into a pool. The watch is protected by a sapphire crystal, known for its exceptional hardness and scratch resistance. This ensures that your timepiece maintains its clarity and beauty over time, even with daily wear and tear. The Oyster case is a hallmark of Rolex, symbolizing durability and water resistance. The Datejust 31's case is not just functional; its polished finish and rounded shape provide a comfortable fit on the wrist, making it suitable for all-day wear. The watch comes with a classic Oyster bracelet, which is both sturdy and stylish. Made from the same high-quality materials as the case, this bracelet features links that are comfortable and secure, ensuring that the watch stays in place as you go about your day. Plus, the clasp is designed for easy adjustment, so you can achieve that perfect fit without hassle.
