The Oyster Perpetual, the purest expression of the Oyster concept.

The direct descendant of the original Oyster launched in 1926, which was the first waterproof wristwatch in the world and the foundation upon which Rolex built its reputation. The Oyster Perpetual features all the key characteristics of the Oyster Perpetual collection – the waterproof Oyster case, a mechanical self-winding movement via the Perpetual rotor and excellent chronometric precision.
