Pink Dial
The sunray finish creates delicate light reflections on many dials in the Oyster Perpetual collection. It is obtained using masterful brushing techniques that create grooves running outwards from the centre of the dial. Light is diffused consistently along each engraving, creating a characteristic subtle glow that moves depending on the position of the wrist. Once the sunray finish has been completed, the dial colour is applied using Physical Vapour Deposition or electroplating. A light coat of varnish gives the dial its final look.

Oystersteel
Rolex uses Oystersteel for its steel watch cases. Specially developed by the brand, Oystersteel belongs to the 904L steel family, alloys most commonly used in high-technology and in the aerospace and chemical industries, where maximum resistance to corrosion is essential. Oystersteel is extremely resistant, offers an exceptional finish once polished and maintains its beauty even in the harshest environments.

The Oyster bracelet
The Oyster bracelet is a perfect alchemy of form and function, aesthetics and technology. 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.
Watches in the Oyster Perpetual range are direct descendants of the original Oyster, the world’s first waterproof wristwatch, on which Rolex has built its reputation since 1926. These watches benefit from all the fundamental features of the Oyster Perpetual collection – excellent chronometric precision, a waterproof Oyster case, and self-winding of the movement via a Perpetual rotor. Displaying hours, minutes and seconds, made exclusively of Oystersteel and featuring a sophisticated finish, these are chronometer wristwatches in their purest form.
