Platinum
Rare and precious, platinum is striking for its silvery whiteness and vibrant luminosity. It is among the densest and heaviest metals in the world, distinguished by unique chemical and physical properties such as exceptional corrosion resistance. Paradoxically, it is also soft, elastic and highly malleable, which makes machining and polishing especially difficult, demanding an extremely high degree of skill. Rolex always uses 950 platinum, an alloy consisting of 950‰ (thousandths) platinum, painstakingly crafted in-house by the fine metalworkers at Rolex. The noblest of metals for the finest of watches.
Diamond Paved Dial
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.
The President bracelet
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.
3255 Movement
The Day-Date 40 is equipped with a new-generation movement, calibre 3255, entirely developed and manufactured by Rolex for a superlative level of performance. This self-winding mechanical movement is at the forefront of the art of watchmaking. A consummate demonstration of Rolex technology, with 14 patents, it offers fundamental gains in terms of precision, power reserve, resistance to shocks and magnetism, ease of use and reliability.
Monday, Lundi
Initially presented in 1956, the Day-Date was a world first. The first watch to indicate the day of the week spelt out in full. Worn by many world leaders, the Day-Date is available with a bespoke day display in a wide choice of languages.
