Oyster Perpetual 31 Bright Black Index

THE QUINTESSENTIAL OYSTER

The purest expression of the Oyster concept, the Oyster Perpetual provides a clear and accurate time display.

The Oyster Perpetual is the direct descendant of the original Oyster launched in 1926, the first waterproof wristwatch in the world and the foundation on which Rolex has built its reputation. A certified Superlative Chronometer, the Oyster Perpetual features all the key characteristics of the Oyster Perpetual collection – the waterproof Oyster case, a mechanical self-winding movement via Perpetual rotor, and excellent chronometric precision. Understated and elegant, this timepiece is known for its universal, classic style. The Oyster Perpetual’s Oyster case guarantees waterproof to a depth of 100 meters (330 feet), being a paragon of robustness and reliability. The Oyster Perpetual models are equipped with calibre 2232 (Oyster Perpetual 28, Oyster Perpetual 31 and Oyster Perpetual 34), or calibre 3230 (Oyster Perpetual 36 and Oyster Perpetual 41), self-winding mechanical movements entirely developed and manufactured by Rolex.
