Bright blue 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 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 Jewelers, who receive regular deliveries and independently manage the allocation and sales of watches to customers.
Ben Bridge is proud to be part of the worldwide network of Official Rolex Jewelers and can provide information on the availability of Rolex watches.
