18 ct gold
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.


Mother of Pearl Dial
Mother-of-pearl is by its nature full of mystery and surprises. Depending on its origin, it can be pink, white, black or yellow. It differs in colour, intensity and structure according to the part of the shell from which it is extracted. At Rolex, mother-of-pearl is never artificially coloured. Instead, particular know-how and skill are devoted to simply highlighting its natural beauty and preserving the original hues. As all mother-of-pearl dials are unique pieces, an identical dial will never be found on another wrist.
Pearlmaster 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. Both sensual and sophisticated, this solid gold bracelet with rounded five-piece links was created in 1992 for the launch of the Pearlmaster model. The Pearlmaster bracelet is always fitted with a concealed Crownclasp.


3235 Movement
The new Pearlmaster 39 is equipped with a new generation movement, calibre 3235, entirely developed and manufactured by Rolex for a superlative level of performance. Certified as a Swiss chronometer by COSC (Swiss Official Chronometer Testing Institute), it is tested a second time by Rolex after being cased to ensure that in everyday use it satisfies Rolex’s criteria for precision, which are twice as exacting as those for an officially certified chronometer. This control of the final precision of the assembled watch is carried out using a methodology and high-technology equipment specially developed by Rolex.

The Cyclops Lens
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.
