The Oyster Perpetual Day-Date 40 in 18 kt Everose gold with a chocolate 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.
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, always in gold.
CHOCOLATE DIAL
A WATCHMAKING TECHNIQUE
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.
18 KT EVEROSE GOLD
AN EXCLUSIVE PATENT
To preserve the beauty of its pink gold watches, Rolex created and patented an exclusive 18 kt pink gold alloy cast in its own foundry: Everose gold. Introduced in 2005, 18 kt Everose is used on all Rolex Oyster models in pink gold.
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.
DAY DISPLAY
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.
3255 MOVEMENT
SUPERLATIVE PERFORMANCE
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.
