It was, at the time, the world’s first waterproof case for a wristwatch, thanks to its system of screwing down the bezel, case back and winding crown against the middle case. Equipped with an Oyster case in Oystersteel made in our workshops, the Oyster Perpetual is guaranteed waterproof to a depth of 100 metres (330 feet), as confirmed by the tests carried out as part of the ... First introduced in the late 1930s, this particularly robust and comfortable metal bracelet with its broad, flat three-piece links remains the most universal bracelet in the Oyster collection. For the Oyster Perpetual models the Oyster bracelet is fitted with an Oysterclasp. The Oyster Perpetual welcomes three new pastel dial shades – lavender, beige and pistachio – with lacquering and a smooth, matt finish. More on rolex.com. A certified Superlative Chronometer, the Oyster Perpetual features all the key characteristics of the Oyster Perpetual collection – excellent chronometric precision, the waterproof Oyster case, and a mechanical self-winding movement via Perpetual rotor.
