The Oyster Perpetual DAY-DATE 36 Oyster, 36 mm, yellow gold DAY-DATE 36 From its launch in 1956, the Day-Date was immediately recognized as the watch worn by influential people. The DayDate was the first calendar wristwatch to display the day, as well as the date, in its entirety. Faithful to its noble origins, the DayDate is made exclusively of gold or platinum, the most precious metals.

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. 5 Spirit of the Day-Date 36 LEADERSHIP Rolex watches have long been associated with those who have, over time, guided the destiny of the world. No matter how different their vision, their field of excellence or their achievements, many of these exceptional men and women have one thing in common: the Day-Date. 6 Features OYSTER CASE The Oyster case is guaranteed waterproof to a depth of 100 metres (330 feet). Its middle case is crafted exclusively from a solid block of 950 platinum or 18 ct gold. The fluted case back is hermetically screwed down with a special tool exclusive to Rolex. Another core component in the watertight structure is the winding crown fitted with the patented Twinlock double waterproofness system, which screws down securely against the case. The sapphire crystal is clamped tight by the bezel. The Oyster case provides the high-precision Rolex movement with optimal protection from water, dust, pressure and shocks. 7 Features LEATHER STRAPS AND GOLD FOLDING CLASP The straps of the new Day-Date combine the comfort and nobility of alligator leather with the convenience of a new 18 ct gold adjustable Crownclasp. This folding clasp is effortless to use and allows the length of the strap to be easily adapted. 8 Features OYSTER BRACELET The Oyster bracelet is a perfect alchemy of form and function, aesthetics and technology. Introduced in the late 1930s, this particularly robust metal bracelet with its broad, flat three-piece links remains the most universal bracelet in the Oyster collection. 9 Features PRESIDENT BRACELET This metal bracelet with semi-circular three piece links was created in 1956 for the launch of the Oyster Perpetual Day-Date. Representing the ultimate in refinement and comfort, and made of carefully selected precious metals, the President bracelet was specifically designed for the exclusive Day-Date. It is also available on some versions of the Datejust in precious metals. The President bracelet is fitted with a concealed Crownclasp. 10 Features 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. 12 Features SUPERLATIVE CHRONOMETER The green seal accompanying every Rolex watch is a symbol of its status as a Superlative Chronometer. This exclusive designation attests that it has successfully undergone a series of specific final controls by Rolex in its own laboratories according to its own criteria, in addition to the official COSC certification of its movement. This unique testing of the chronometric precision of the cased-up movement, as well as of the watch’s waterproofness, self-winding and power reserve, pushes back the boundaries of performance and makes Rolex the benchmark for excellence in mechanical watches. The green seal is coupled with a five‑year guarantee which applies to all Rolex models. 13 Where to buy a Rolex THE OFFICIAL ROLEX RETAILER Only official Rolex retailers, distinguishable by this official green plaque, are allowed to sell and maintain a Rolex.
