VINTAGE PARIS > Watches > Rolex Rolex Sea-Dweller ENQUIRY Contact Customer Service ENQUIRY Some of the most important milestones in watchmaking are attributed to Rolex. In 1926, Rolex introduced the Oyster case, the first waterproof wristwatch case that was fitted with a screw-down crown to keep moisture and dust from damaging the movement. Five years later in 1931, the brand introduced the first self-winding rotor on its Perpetual line, which ensured that the mainspring barrel was consistently wound. In 1945, the Datejust became the first chronometer wristwatch with an automatically changing date function.
