Precious materials
In 1956, the Oyster Perpetual Day-Date made its debut. Available only in 18 ct gold or platinum, it was the first wristwatch to display the date and day of the week spelt out in full in a window 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.
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 same painstaking attention to quality. Rolex's commitment to excellence begins at the source.
Champagne Dial
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 18 ct gold to prevent tarnishing, every Rolex dial is designed and manufactured in-house, largely by hand to ensure perfection.
The Oyster bracelet
The Day-Date's Oyster bracelet is available in 18 ct yellow, white or Everose gold with a concealed folding Crownclasp. This elegant, solid-link bracelet combining satin and polished finishes is remarkably comfortable to wear and effortless to open and close.
3155 Movement
The Day-Date 36 is equipped with calibre 3155, a self-winding mechanical movement entirely developed and manufactured by Rolex. It features a day and date calendar disc mechanism. Like all Rolex Perpetual movements, the 3155 is a certified Swiss chronometer, a designation reserved for high-precision watches that have successfully passed the Swiss Official Chronometer Testing Institute (COSC) tests. Its architecture, in common with all Oyster watch movements, makes it singularly reliable.
Monday, Lundi
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.
