Datejust 31
Oyster, 31 mm, Everose gold
Make a date of a day
This Oyster Perpetual Datejust 31 in 18 ct Everose gold features a white mother-of-pearl, diamond-set dial and a President bracelet.
Mother-of-Pearl Dial
Highlighting natural beauty
This dial features diamonds in 18 ct gold settings. 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 Datejust 31.
18 ct Everose gold
An exclusive patent
To preserve the beauty of its pink gold watches, Rolex created and patented an exclusive 18 ct pink gold alloy cast in its own foundry: Everose gold.
Introduced in 2005, 18 ct Everose is used on all Rolex Oyster models in pink gold.
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.
