The Oyster Perpetual Day-Date 40 in 18 ct white gold, with a meteorite, diamond-set dial, diamond-set bezel and a President bracelet.
This dial features 10 baguette-cut diamonds. Formed in the far reaches of the solar system, metallic meteorite comes from an asteroid that exploded millions of years ago. On the voyage between planets, fragments of this natural extraterrestrial material, primarily composed of iron and nickel, cool by a few degrees Celsius every million years, creating unique, distinctive crystallization within the material that is impossible to recreate on Earth. Metallic meteorite is rare and challenging to work with, but once it is cut into thin sections and a chemical treatment is applied, the great beauty of its interwoven internal structure is revealed. These
fascinating and varied formations are known as
Widmanstätten patterns. For its dials, Rolex works
with leading experts in the field and selects only
the sections of meteorite with a particularly wellformed surface rich in different shapes and
reflections.
Gem-setters, like sculptors, finely carve the precious metal to hand-shape the seat in which each gemstone will be perfectly lodged. With the art and craft of a jeweller, the stone is placed and meticulously aligned with the others, then firmly secured in its gold or platinum setting. Besides the intrinsic quality of the stones, several other criteria contribute to the beauty of Rolex gem-setting: the precise alignment of the height of the gems, their orientation and position, the regularity, strength and proportions of the setting as well as the intricate finishing of the metalwork. A sparkling symphony to enhance the watch and enchant the wearer.
By operating its own exclusive foundry, Rolex has the unrivalled ability to cast the highest quality 18 ct gold alloys. According to the proportion of silver, copper, platinum or palladium added, different types of 18 ct 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 the same painstaking attention to quality. Rolex’s commitment to excellence begins at the source.
The design, development and production of Rolex bracelets and clasps, as well as the stringent tests they face, involve advanced high technology. And, as with all the components of the watch, aesthetic controls by the human eye guarantee impeccable beauty. The President bracelet, with its semi-circular three piece links, was created in 1956 for the launch of the Oyster Perpetual Day-Date. It represents the ultimate in refinement and comfort and is always made of carefully selected precious metals.
