What a Difference
a Date Makes
Function of the Datejust II
Influenced by the pioneering Datejust, the date on the Datejust II is displayed in a window at 3 o’clock and changes instantaneously at midnight in a few thousandths of a second. The Cyclops lens on the crystal, invented by Rolex in 1953, magnifies the date two and a half times for easy reading.
Birth of the Oyster
Spirit of the Datejust II
The Oyster bracelet is a perfect alchemy of form and function, aesthetics and technology. First introduced in the late 1930s, this particularly robust and comfortable metal bracelet with its broad, flat three-piece links remains the most universal bracelet in the Oyster collection.
The Cyclops Lens
The Cyclops lens enhances the date aperture, magnifying the date display by two and half times for easy reading. It is one of the most distinctive Rolex features, and one of the most recognisable.
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.
