THE OYSTER PERPETUAL DAY-DATE 40 IN 18 KT YELLOW GOLD WITH A CHAMPAGNE COLOUR, DIAMOND-SET DIAL, FLUTED BEZEL AND A PRESIDENT BRACELET.
The Day-Date was the first watch to indicate the day of the week spelt out in full when it was first presented in 1956.
A DISTINCTIVE FACE
The dial is the distinctive face of a Rolex watch, the feature most responsible for its identity and readability.
Characterised by hour markers fashioned from gold to prevent tarnishing, every Rolex dial is designed and manufactured in-house, largely by hand to ensure perfection.
THE FLUTED BEZEL
A ROLEX SIGNATURE
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 Day-Date 40.
18 KT YELLOW GOLD
COMMITMENT TO EXCELLENCE
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.
THE PRESIDENT BRACELET
THE ULTIMATE REFINEMENT
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 President bracelet, with its semi-circular three piece links, was created in 1956 for the launch of the Oyster Perpetual Day-Date. It represents the ultimate in refinement and comfort and is always made of carefully selected precious metals.
INSTANTANEOUS AT MIDNIGHT
Initially presented in 1956, the Day-Date was a world first. The first watch to indicate the day of the week spelt out in full. Worn by many world leaders, the Day-Date is available with a bespoke day display in a wide choice of languages.
THE CYCLOPS LENS
A MAGNIFYING LENS
The Cyclops lens is one of the most distinctive Rolex features, and one of the most recognizable. Named after the one-eyed giant of Greek mythology, the Cyclops lens magnifies the watch’s emblematic date display two and a half times for easy reading. Behind the Cyclops, as with every feature of a Rolex timepiece, lies a history of invention, research and development, and the endless search for perfection.
The Day-Date 40 is equipped with a new-generation movement, calibre 3255, entirely developed and manufactured by Rolex for a superlative level of performance. This self-winding mechanical movement is at the forefront of the art of watchmaking. A consummate demonstration of Rolex technology, with 14 patents, it offers fundamental gains in terms of precision, power reserve, resistance to shocks and magnetism, ease of use and reliability.
