Oystersteel Its middle case is crafted exclusively from a solid block of Oystersteel, a particularly corrosion-resistant alloy. The case back, edged with fine fluting, is hermetically screwed down with a special tool exclusive to Rolex watchmakers.

The watches benefit from all the fundamental features of the Oyster Perpetual collection – excellent chronometric precision, a waterproof Oyster case, and self-winding of the movement via a Perpetual rotor.

The perfect embodiment of the classic Rolex watch, the original Datejust showcased all of the brand's major accomplishments to that point, with a certified chronometer movement, a self-winding mechanism and a waterproof case, complemented by the date display in a special window on the dial.

The Rolex Oyster Perpetual Datejust is a certified, self-winding chronometer wristwatch manufactured by Rolex. When it was launched in 1945, the Datejust was the first self-winding chronometer wristwatch to indicate the date in a window on the dial.

By smelting their own metals, Rolex can ensure that only the highest quality materials are used in he construction of their watches. Some vintage references use 14 karat and 10 karat gold; however 18 karat has become the Rolex standard, and every modern gold Rolex watch only uses solid 18k gold parts.

And there's the surrounding dial. Again this isn't always the case but if you do see it. It's a fake cool. Okay so this one is more the finishing. Feel of a fake Rolex versus a genuine one. Now.

This movement uses a weight to gently wind the watch as it is being worn on the wrist, and thus the word 'Perpetual' was added as the watch could be perpetually wound. It wouldn't be until around 1945 when the name 'Oyster Perpetual' would be seen, combining the robust Oyster case with the self-winding movement.

Rolex's Datejust is the archetype of the classic watch thanks to functions and aesthetics that never go out of fashion. At its launch in 1945, it was the first self-winding waterproof chronometer wristwatch to display the date in a window at 3 o'clock on the dial – hence its name.

While on the replica. One most of the times. It might be some dials might be aligned with the with engravings.
