By operating its own exclusive foundry, Rolex has the unrivalled ability to cast the highest quality 18 ct gold alloys. According to the proportion of silver, copper, platinum or palladium added, different types of 18 ct gold are obtained: yellow, pink or white. They are made with only the purest metals and meticulously inspected in an in-house laboratory with state-of-the-art equipment, before the gold is formed and shaped with the same painstaking attention to quality. Rolex's commitment to excellence begins at the source.
The dial is the distinctive face of a Rolex watch, the feature most responsible for its identity and readability. Characterised by hour markers fashioned from 18 ct gold to prevent tarnishing, every Rolex dial is designed and manufactured in-house, largely by hand to ensure perfection.
The design, development and production of Rolex bracelets and clasps, as well as the stringent tests they face, involve advanced high technology. And, as with all the components of the watch, aesthetic controls by the human eye guarantee impeccable beauty. The Jubilee, a supple and comfortable five-piece link metal bracelet, was designed and made especially for the launch of the Oyster Perpetual Datejust in 1945.
The new Lady-Datejust 28 watches are equipped with calibre 2236, a new-generation self-winding mechanical movement entirely developed and manufactured by Rolex. Fitted with a Syloxi hairspring in silicon, patented by Rolex, 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.
The Cyclops lens enhances the date aperture, magnifying the date display for easy reading. It is one of the most distinctive Rolex features, and one of the most recognisable.
