Datejust is a classic example of classic watches, both in function and aesthetic style, are always new. Introduced in 1945, this watch is the world’s first self-winding waterproof observatory certified watch with a calendar window at 3 o’clock. The watch embodies all the major innovations of Rolex at the time, setting a milestone for modern watchmaking. From an aesthetic point of view, after different years of Datejust, the original aesthetic features are still retained. As a result, Datejust has become one of the most recognizable watches.

The bezel of the Datejust 31 in white gold is set with a total of 46 round-cut diamonds. The fine and regular setting shows the brand’s craftsmanship.

The Datejust 31’s oyster case is guaranteed to be water-resistant to 100 meters, a model of solidity and elegance. The delicate middle case is cast from a solid piece of 18ct yellow gold, 18ct white gold, and 18ct eternal rose gold. Rolex watchmakers use the brand’s exclusive tools to tighten the fine pitted bottom cover to seal the case, so only Rolex watchmakers can access the movement. The winding crown is equipped with a double-lock double waterproof system and is firmly screwed to the case. The mirror is made of sapphire and is not easily scratched. A small window convex lens is installed at 3 o’clock for easy reading of the calendar. The waterproof oyster case gives the Datejust 31’s high-precision movement the best protection.
