Day-Date 36Oyster, 36 mm, white gold
The Oyster Perpetual Day-Date 36 in 18 ct white gold with a diamond-paved 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.


Diamond-Paved Dial
A sparkling symphony
The diamond-paved dials are a sparkling symphony to enhance the watch and enchant the wearer. Gem-setters finely carve the precious metal to hand-shape the seat in which each gemstone will be perfectly lodged.
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.
