The world is your oyster

This is our Oyster case, the world’s first waterproof wristwatch case, conceived by Rolex in 1926 and patented. A one-of-a-kind feature, which holds within it an intricate world of cogs and minutely crafted parts. Made of some of the most refined alloys, the Oyster case is incomparably resistant to all sorts of external aggressions.

Yet no object so hermetic, so immovable, has ever opened the door to so many possibilities. With its original patented design consisting of a bezel, a case back and a winding crown screwed down against the middle case, it profoundly changed the course of watchmaking history and set new standards of waterproofness for all wristwatches. To this day, the Oyster case continues to protect our watches and our movements within them. It stands as undeniable proof of our constant quest for reliability.
