Ideal accomplishments
The Oyster Perpetual Day-Date 36 in 18 ct white gold with a white mother-of-pearl, diamond-set dial, fluted bezel and a diamond-set President bracelet.
Mother-of-Pearl Dial
Highlighting natural beauty
This dial features 10 baguette-cut diamonds. Mother-of-pearl is by its nature full of mystery and surprises. Depending on its origin, it can be pink, white, black or yellow. It differs in colour, intensity and structure according to the part of the shell from which it is extracted.
At Rolex, mother-of-pearl is never artificially coloured. Instead, particular know-how and skill are devoted to simply highlighting its natural beauty and preserving the original hues. As all mother-of-pearl dials are unique pieces, an identical dial will never be found on another wrist.
Fluted bezel
A Rolex signature
The Rolex fluted bezel is a mark of distinction. Originally, the fluting of the Oyster bezel had a functional purpose: it served to screw the bezel onto the case helping to ensure the waterproofness of the watch.
It was therefore identical to the fluting on the case back, which was also screwed onto the case for waterproofness, using specific Rolex tools. Over time, the fluting became an aesthetic element, a genuine Rolex signature feature. Today the fluted bezel is a mark of distinction, in gold on this Day-Date 36.
18 ct white 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.
