The 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.

Champagne-color Dial
The sunray finish on Rolex dials is a predominant method in watchmaking of achieving pure metallic color dials such as shades of silver grey, rhodium or ruthenium. Silver-plating is mostly used as a base layer for the sunray finish, where further color is added to the prepared dial. Sometimes colors such as champagne are achieved through electroplating with more than half a dozen different metals. -

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.
C.D.Peacock is proud to be part of the worldwide network of Official Rolex Jewelers and can provide information on the availability of Rolex watches.
The Rolex Day-Date made its debut in 1956. Available only in 18 kt gold or platinum, it was the first wristwatch chronometer to display the date and the day of the week spelled out in full in windows on the dial. With the President bracelet, originally created specially for it, the Day-Date continues to be the watch par excellence of influential people.
