Dark Grey Dial
This dial features a large VI set
with 11 diamonds. 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.
Fluted bezel
The Rolex fluted bezel is a mark of
distinction. Originally, the fluting of the Oyster bezel had a functional purpose:
it served to screw the bezel onto the case helping to ensure the waterproofness of
the watch. It was therefore identical to the fluting on the case back, which was
also screwed onto the case for waterproofness, using specific Rolex tools. Over
time, the fluting became an aesthetic element, a genuine Rolex signature feature.
Today the fluted bezel is a mark of distinction, in gold on this Datejust
31.
18 kt yellow gold
By operating its own exclusive
foundry, Rolex has the unrivalled ability to cast the highest quality 18 kt gold
alloys. According to the proportion of silver, copper, platinum or palladium added,
different types of 18 kt 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.
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.
