The Classic Watch
Style of the Datejust
The Datejust is the modern archetype of the classic watch, thanks to aesthetics and functions that transcend changes in fashion. Aesthetically, the Datejust has spanned eras, while retaining the enduring codes that make it, notably in its traditional versions, one of the most recognised and recognisable of watches.
What a Difference
a Date Makes
Function of the Datejust
The Datejust was the first self-winding waterproof chronometer wristwatch to display the date in a window at 3 o’clock on the dial – hence its name. In the earliest models, the date would begin to change hours before its midnight rendezvous. In 1955, the date-change mechanism was adapted to operate instantaneously and the date aperture was enhanced with a Cyclops lens, magnifying the date by two and half times for easy reading.
Spirit of the Datejust
The Datejust, introduced in 1945, was the first wristwatch to display the date through an aperture on the dial. Its unique magnifying Cyclops eye, added several years later, became recognised as a Rolex standard. Admired for its classic design, the Datejust has become an iconic symbol of style.
The Mystery Man
Spirit of the Datejust
In 1947, commemorating the brand's 100,000th officially certified chronometer, Hans Wilsdorf presented that selfsame Datejust to an illustrious gentleman he described as one of the greatest figures of our time. To this day, his identity has never been revealed.
Twinlock Winding Crown
The screw-down winding crown and the case with screw-down back form the core of the Oyster. Created by Rolex in 1953, the Twinlock system ensures that the screw-down crown is
water-resistant thanks to two sealed zones, one inside the tube of the crown, the other inside the winding crown itself. This system is used on all the watches in the Oyster collection that are guaranteed waterproof to 100 metres (330 feet).
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.
The Jubilee, a supple and comfortable five-piece link metal bracelet, was designed and made especially for the launch of the Oyster Perpetual Datejust in 1945. The Jubilee is fitted with a concealed Crownclasp.
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 Oyster Case
The Oyster case is one of the foundations of the reputation for excellence of Rolex watches. Invented by Rolex in 1926, it was the world’s first waterproof case for a wristwatch thanks to its patented system of screwing down the bezel, case back and winding crown against
the middle case.
Like the mollusc, the Rolex Oyster is robust and clamped shut. It provides a hermetic environment that protects the high-precision Perpetual movement from water, dust, or pressure.
