About this watch
The Rolex Datejust 31 is a masterpiece of horological excellence, boasting a stunning aesthetic with its white gloss finish and Roman numeral indexes. The round case measures 31mm in diameter, making it the perfect size for those who prefer a slightly smaller profile without compromising on presence. The sapphire glass not only protects the dial but also adds a layer of depth to the watch face, enhancing its visual allure. Inside beats the Rolex Caliber 2236, a self-winding mechanical movement that marks a new era in watchmaking innovation. This movement is entirely manufactured by Rolex, showcasing their commitment to quality and precision. With a power reserve of 55 hours, you can confidently leave your watch unworn for a couple of days without worrying about it losing time. The movement also operates at a frequency of 28,800 vibrations per hour, ensuring that it’s both precise and robust. One of the standout features of the 2236 is its Syloxi hairspring, made from silicon. This innovation allows for greater resistance to shocks and magnetic fields, providing enhanced reliability. With a water resistance of up to 100 meters, the Rolex Datejust 31 is built to withstand the elements, making it perfect for any occasion, whether you’re at the office or out on a weekend adventure.
