This Oyster Perpetual Lady-Datejust in 18 ct yellow gold features a diamond-paved dial and a Jubilee bracelet.

Diamonds, sapphires, rubies, emeralds – the noblest and most precious stones are selected to grace Rolex timepieces. The brand has in-house expertise and equipment enabling it to bejewel any model in its catalogue. Experienced gemmologists first select gemstones of the highest quality. For this, they can rely on their own seasoned judgement as well as state-of-the-art analysis equipment. The stones are then entrusted to the gem-setters, who skilfully place each precious stone onto the watch by hand, one by one, assuring precision to within hundredths of a millimetre. Such stringent tolerances guarantee that each stone shines with optimal brilliance and is perfectly aligned with those around it. These time-honoured gestures, which may be repeated many hundreds of times, ensure that each gem-set watch produced by Rolex sparkles with exceptional intensity and reflects the standard of excellence required by the brand.

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 Lady-Datejust.

By operating its own exclusive foundry, Rolex has the unrivalled ability to cast the highest quality 18 ct gold alloys. According to the proportion of silver, copper, platinum or palladium added, different types of 18 ct gold are obtained: yellow, pink or white. They are made with only the purest metals and meticulously inspected in an in-house laboratory with state-of-the-art equipment, before the gold is formed and shaped with the same painstaking attention to quality. Rolex's commitment to excellence begins at the source.

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 Jubilee, a supple and comfortable five-piece link metal bracelet, was designed and made especially for the launch of the Oyster Perpetual Datejust in 1945.

The Cyclops lens is one of the most distinctive Rolex features, and one of the most recognizable. Named after the one-eyed giant of Greek mythology, the Cyclops lens magnifies the watch’s emblematic date display for easy reading. Behind the Cyclops, as with every feature of a Rolex timepiece, lies a history of invention, research and development, and the endless search for perfection.

The calibre 2236 is a new-generation self-winding mechanical movement entirely developed and manufactured by Rolex. Fitted with a Syloxi hairspring in silicon, patented, it offers a superlative level of chronometric performance. Insensitive to magnetic fields, the Syloxi hairspring provides great stability in the face of temperature variations and remains up to 10 times more precise than a traditional hairspring in case of shocks. Its patented geometry ensures its regularity in any position.
