Description
The prowess of the essential
The Oyster Perpetual 31 in Oystersteel with a med blue dial and an Oyster bracelet.
Med blue dial
Craftsmanship rhymes with high technology
The colours created for the Oyster Perpetual range start life as a lacquer, which must be meticulously applied in a controlled-atmosphere environment to avoid dust and other contamination. The brass plate of the dial base receives layer upon layer of lacquer, six in all, to form a regular, uniform surface. The last step is varnishing and polishing to bring out the full brilliance and depth of colour. The various inscriptions are then pad printed, and the hour markers and crown riveted by hand. The dial, gleaming in its perfection, is all set to take its place on top of the movement at the watch assembly phase.
Oystersteel
Highly resistant to corrosion
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
Alchemy of form and function
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.
2232 movement
Superlative performance
Unveiled in 2020, calibre 2232 is a new-generation self-winding mechanical movement entirely developed and manufactured by Rolex. Fitted with a Syloxi hairspring in silicon, patented, it offers a superlative level of chronometric performance. Insensitive to magnetic fields, the Syloxi hairspring provides great stability in the face of temperature variations and remains up to 10 times more precise than a traditional hairspring in case of shocks. Its patented geometry ensures its regularity in any position.
