- Oyster, 26 mm, white gold and diamonds
- Oyster architecture
- Monobloc middle case, screw-down case back and winding crown
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.
- 26 mm
- 18 ct white gold
18 ct gold
By operating its own exclusive foundry, Rolex has the unrivalled ability to cast the highest quality 18ct gold alloys. According to the proportion of silver, copper, platinum or palladium added, different types of 18ct 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.
- Set with diamonds
Rolex selects only the finest, colourless diamonds from reputable and trusted sources for its gem-set bezels. Each gemstone is carefully checked by Rolex’s in-house gemmology experts according to the four key criteria determining diamond quality: carat, clarity, colour and cut. Once sorted, they are passed
on to specialist gem setters, true masters of their art, whose craft provides a scintillating enhancement
to a Rolex watch, and the owner’s wrist.
- Winding crown
- Screw-down, Twinlock double waterproofness system
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).
- Scratch-resistant sapphire, Cyclops lens (2.5x) over the date
The Cyclops lens
The Cyclops lens enhances the date aperture, magnifying the date display by two and a half times for easy reading. It is one of the most distinctive Rolex features, and one of the most recognizable.
- Waterproof to 100 metres / 330 feet
The watch case is rigorously tested to ensure it meets pressure-resistance requirements. The three-step process - a vacuum test, a compression test and a condensation test - will reveal the presence of even the smallest amount of moisture inside the case.
- Perpetual, mechanical , self-winding
- 2235, Manufacture Rolex
The Datejust Special Edition is equipped with calibre 2235, a self-winding mechanical movement entirely developed and manufactured by Rolex. Like all Rolex Perpetual movements, the 2235 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.
- Centre hour, minute and seconds hands. Instantaneous date with rapid setting. Stop-seconds for precise time setting
- Officially certified Swiss chronometer (COSC)
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.
- Bidirectional self-winding via Perpetual rotor
Invented by Rolex in 1931, this ingenious mechanism harnesses the energy of natural wrist movements to provide a reliable and clean source of power for the watch movement. It consists of a half-moon- shaped oscillating weight, which pivots freely in both directions on its axle. As it rotates, the rotor continuously winds the Perpetual movement’s mainspring, ensuring a constant and stable source of energy. This enhances the watch’s precision and eliminates the need to wind it regularly. The Perpetual rotor mechanism features two distinctive red reversing wheels, which ensure efficient winding of the movement regardless of the direction in which the oscillating weight rotates.

Femininity in All
Style of the Lady-Datejust
Crafted in 904L steel, 18 ct gold or gem-set platinum,
the Lady-Datejust comes in a wealth of versions to perfectly
reflect the different personalities of its wearers. The range of
materials and colours of the Lady-Datejust is equalled only
by the variety of bracelets and dials that add to its style.
What a Difference
a Date Makes
Function of the Lady-Datejust
In the earliest models of the Datejust, 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 that magnifies the date by two and a half times for easy reading.
The first Datejust
Spirit of the Lady-Datejust
In 1945, at the dawn of a new era of prosperity, Rolex launched the first Datejust. The inaugural model with its waterproofness, streamlined elegance and date aperture on the face of the watch, was a timepiece ahead of its time.
The Lady-Datejust, which appeared in the late 1950s, was the first ladies’ version of this date chronometer, carrying its heritage of timeless elegance and functionality in a more exquisite size.
Rolex uses only the finest rubies, sapphires and emeralds to adorn its watches, and employs exceptionally demanding selection criteria. Each stone is meticulously examined by the in-house gemmologists for quality and authenticity. Since these coloured gemstones form naturally in the earth in a varied palette of colours, they are sorted by hand, stone by stone, to ensure that all the gems on a given watch are of the same hue. At Rolex, time and precision are ingredients of beauty.
The Infinite Poetry of Gold Crystals
The Gold Crystals dials highlight the natural crystalline structure of gold in a captivating play of reflections and colours. The dials are obtained from a particular surface treatment of an 18 ct gold alloy developed by Rolex and produced in its own foundry. Each Gold Crystals dial is magically different from another,
a natural work of art.

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.
