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.

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.

Il design, lo sviluppo e la produzione dei bracciali e dei fermagli Rolex, nonché i rigorosi test cui vengono sottoposti, sono resi possibili dall’uso di strumentazioni d’avanguardia. La loro bellezza impeccabile, invece, è garantita dagli attenti controlli estetici effettuati personalmente dagli orologiai Rolex su ogni componente dell’orologio. Flessibile e confortevole, il bracciale metallico a cinque file Jubilee è stato creato appositamente per il lancio del modello Oyster Perpetual Datejust nel 1945.
