Style of the Day-Date
The Day-Date has always embodied prestige and exclusivity. A hallmark of its nobility, the Day-Date’s Oyster case is produced exclusively in 950 platinum or in 18 ct gold. The bezel can be fluted, smooth or, on the gem-set versions, arrayed in the most beautiful of precious stones.
A choice of unique dials in refined colours and textures enhances this timeless symbol of excellence.
Function of the Day-Date
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.
Spirit of the Day-Date
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.
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.
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.
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.
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.
The Day-Date 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.
Certified Swiss Chronometer
The four simple words Superlative Chronometer Officially Certified on a Rolex watch dial mean that the very movement inside the timepiece has endured 15 days and nights of testing by COSC (Contrôle Officiel Suisse des Chronomètres – Swiss Official Chronometer Testing Institute), an independent not-for-profit association. To receive COSC certification as a Swiss chronometer, a watch must demonstrate extreme precision in a variety of positions and temperatures. Rolex is unique in the industry: this is the standard level of quality required of every Rolex wristwatch movement.
