METEORITE DIAL
Meteorite comes from the heart of an asteroid or possibly even a planet that has exploded, propelling material across the Solar System until chance brings it into our planet’s orbit and gravity pulls it to Earth. During its journey, the centre of the meteorite is gradually transformed, producing highly unusual metallic patterns, resulting from the very slow cooling of molten asteroid cores. The designers at Rolex create from these configurations a unique treasure for some of the most prestigious models, including this Day-Date 40.
DIAMOND-SET BEZEL
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.
18 CT WHITE GOLD
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.
