Lady-DatejustOyster, 28 mm, yellow gold and diamonds
This Oyster Perpetual Lady-Datejust in 18 ct yellow gold features a white mother-of-pearl, diamond-set dial and a President bracelet.
The light reflections on the case sides and lugs highlight the elegant profile of the 28 mm Oyster case, which is fitted with a diamond-set bezel. Rolex's classic feminine watch, the Lady-Datejust is in the lineage of the Datejust, the emblematic model that has been a byword for style and accurate timekeeping.


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.
