Reference 228348RBR

Ideal accomplishments

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

Diamond-Paved Dial

Optimal brilliance

This dial features 10 baguette-cut diamonds. Diamonds, sapphires, rubies, emeralds – the noblest and most precious stones are selected to grace Rolex timepieces. The brand has in-house expertise and equipment enabling it to bejewel any model in its catalogue.

Experienced gemmologists first select gemstones of the highest quality. For this, they can rely on their own seasoned judgement as well as state-of-the-art analysis equipment. The stones are then entrusted to the gem-setters, who skilfully place each precious stone onto the watch by hand, one by one, assuring precision to within hundredths of a millimetre. Such stringent tolerances guarantee that each stone shines with optimal brilliance and is perfectly aligned with those around it. These time-honoured gestures, which may be repeated many hundreds of times, ensure that each gem-set watch produced by Rolex sparkles with exceptional intensity and reflects the standard of excellence required by the brand.

Diamond-set bezel

A sparkling symphony

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 yellow gold

Commitment to excellence

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 President bracelet

The ultimate refinement

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.
