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 Jubilee bracelet
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.MODEL AVAILABILITY
All Rolex watches are assembled by hand with the utmost care to ensure exceptional
quality. Such high standards naturally restrict Rolex production capacity and, at times,
the demand for Rolex watches outpaces this capacity. Therefore, the availability of
certain models may be limited. New Rolex watches are exclusively sold by Official
Rolex Retailers, who receive regular deliveries and independently manage the
allocation and sales of watches to customers. Panda is proud to be part of the
worldwide network of Official Rolex Retailers and can provide information on the
availability of Rolex watches. -
