Description
The Oyster Perpetual Day-Date 40 in 18 ct Everose gold with a chocolate dial, fluted bezel and a President bracelet.
luted 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.
Slate ombré dial
Continuity of a design
The version presented, in 18 kt Everose gold, introduces slate ombré dial – a completely new hue for such a dial, whose surface, coloured at the centre, progresses to a deep black around the edge. Also appearing for the first time on the ombré dial of this watch are faceted, deconstructed Roman numerals and faceted index hour markers in 18 kt pink gold.
Until now, Rolex ombré dials were set with diamond hour markers and were reserved for the Day-Date 36. This dial represents the continuity of a design that Rolex introduced in the 1980s and relaunched in 2019. The manufacture of these dials with a concentric gradient involves the application of black lacquer, a delicate operation overseen by a specialist whose task it is to ensure the harmonious transition from colour to darkness.
18 kt Everose gold
An exclusive patent
To preserve the beauty of its pink gold watches, Rolex created and patented an exclusive 18 kt pink gold alloy cast in its own foundry: Everose gold.
Introduced in 2005, 18 kt 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.
