2024 New Rolex Day-Date 40 Oyster, 40 mm, yellow gold and diamonds Reference 228348RBR

The Oyster Perpetual Day-Date 40 in 18 kt yellow gold with a green ombré dial, diamond-set bezel and a President bracelet.

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 ombré dial features a coloured surface at the centre, progresses to a deep black around the edge. This dial represents the continuity of a design that Rolex introduced in the 1980s and relaunched in 2019.

The manufacture of these dials with a concentric gradient involves the application of black lacquer, a delicate operation overseen by a specialist whose task it is to ensure the harmonious transition from colour to darkness.

By operating its own exclusive foundry, Rolex has the unrivalled ability to cast the highest quality 18 kt gold alloys. According to the proportion of silver, copper, platinum or palladium added, different types of 18 kt 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.
