Day-Date 36Oyster, 36 mm, platinum
The Oyster Perpetual Day-Date 36 in Platinum with a white mother-of-pearl, diamond-set dial, Fluted bezel and a President bracelet.
The Day-Date was the first watch to indicate the day of the week spelt out in full when it was first presented in 1956.


Mother-of-Pearl Dial
Highlighting natural beauty
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.
