Endless Wonder

Style of the Datejust 31

The 31 mm case gives the Datejust 31 a striking, elegant appearance that is accentuated by the range of different bezels: domed, fluted, graced with brilliants or gem-set with diamonds. The Datejust 31 is available in a variety of materials – 904L steel, 18 ct yellow, white or Everose gold as well as 950 platinum – and a wide choice of enchanting dials with refined colours and decorations, each displaying its own unique character.

In mother-of-pearl, with elaborate patterns – including champagne, pink or rhodium floral motifs – or paved with diamonds, the dials take on delicate shades of endlessly shimmering colour.

What a Difference
A Date Makes

Function of the Datejust 31

Influenced by the pioneering Datejust, the date on the Datejust 31 is displayed in a window at 3 o’clock and changes instantaneously at midnight in a few thousandths of a second. The Cyclops lens on the crystal, invented by Rolex in 1953, magnifies the date for easy reading.

The First Datejust

Spirit of the Datejust 31

The Datejust, introduced in 1945, was the first wristwatch to display the date through an aperture on the dial. Its unique magnifying Cyclops eye, added several years later, became recognised as a Rolex standard. Admired for its classic design, the Datejust has become an iconic symbol of style.

Oyster bracelet

Oyster bracelet


The Oyster bracelet is a perfect alchemy of form and function, aesthetics and technology. First introduced in the late 1930s, this particularly robust and comfortable metal bracelet with its broad, flat three-piece links remains the most universal bracelet in the Oyster collection.

Every Datejust 31 is a Canvas


At Rolex, gem-setting is a work of art. Diamonds are carefully selected using state-of-the-art technology then set by master craftsmen and craftswomen. Rolex maintains the highest standards for every stone used. With great care and dedication, a Rolex gem-setter adds to the beauty of the watch and to the beauty of the stones themselves – creating a work that is greater then the sum of its parts.

2235 Movement

2235 Movement


Calibre 2235 is a self-winding mechanical movement entirely developed and manufactured by Rolex. Like all Rolex Perpetual movements, the 2235 is a certified Swiss chronometer, a designation reserved for high-precision watches that have successfully passed the Swiss Official Chronometer Testing Institute (COSC) tests. Its architecture, in common with all Oyster watch movements, makes it singularly reliable.
