THE CYCLOPS LENS
AN OPTIMIZED READING
Created to improve the legibility of the date, the Cyclops lens is both an aesthetic and a technical brand signature. This Rolex invention, named after the one-eyed giant in Greek mythology, was patented in the early 1950s and presented for the first time in 1953 on a Datejust. Its magnifying effect makes the date easier to read. Initially in plexiglass, it has been crafted in sapphire since the 1970s, like the watch’s crystal. Virtually impervious to scratches, the sapphire now features a double anti-reflective coating, making it even more effective.

THE DIALS
INFINITE FACES
With a large selection of dials, the Datejust offers the most varied combinations of all Rolex watches. Set with diamonds or made from mother-of-pearl, adorned with palm or fluted motifs, or featuring a sunray finish, the Datejust dials offer a host of faces available in a wide variety of materials, colours and motifs, with different hour markers (index or Roman or Arabic numerals) and multiple gem-setting possibilities. Bearing chief responsibility for the identity and legibility of Rolex watches, all the brand’s dials are developed in-house for optimal results.

THE BEZEL
A DISTINCTIVE FEATURE
Smooth, fluted, domed or set with diamonds, the varied bezels allow the Datejust to reflect the personality of the wearer. The bezel is one of the watch’s most visible features and one of the most emblematic aspects of Rolex know-how. It can therefore be set with brilliant-cut diamonds, selected in-house by experts to ensure they sparkle beautifully. An iconic Rolex signature, the fluted bezel is crafted from 18 ct yellow, white or Everose gold.

AN ICON OF ROLEX KNOW-HOW

THE 31, 36 OR 41 MM OYSTER CASE
A SYMBOL OF WATERPROOFNESS
The Datejust’s case, 31 mm, 36 mm or 41 mm in diameter and guaranteed waterproof to a depth of 100 metres (330 feet), is a paragon of robustness and reliability. The middle case is crafted from a solid block of Oystersteel, a particularly corrosion-resistant alloy, or 18 ct gold. The case back, edged with fine fluting, is hermetically screwed down with a special tool that grants only Rolex watchmakers access to the movement.

The Twinlock winding crown, fitted with a double waterproofness system, screws down securely against the case. Completely waterproof, the Oyster case provides optimum protection for the Datejust’s movement.
