Description
The achievement of an ideal
The Oyster Perpetual Day-Date 40 in 18 kt Jubilee Gold with a light green aventurine dial, fluted bezel and a President bracelet.
Light green aventurine dial
Elevated with diamonds
This dial is cut from light green aventurine, a natural stone in the quartz family, distinctive for its soft green colour with touches of stronger green and for its delicate veining. It is adorned with an hour circle of ten baguette-cut diamonds.
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 Day-Date 40.
Jubilee Gold
A gentle shine
This metal with a sophisticated hue and subtle reflections was unveiled on this exclusive version of the Oyster Perpetual Day-Date 40. The 18 kt gold alloy was conceived, developed and produced in the brand’s workshops and named Jubilee Gold. It glows with tones of tender yellow, warm grey and soft pink.
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.
