The Oyster case, the world’s first waterproof wristwatch case, houses an intricate world of cogs and minutely crafted parts, and is incomparably resistant to all sorts of external aggressions.

With the original 1926 patented design consisting of a bezel, case back and 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. It remains an emblem of our constant quest for reliability.
