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.
