The Oyster Perpetual Day-Date 36 in 18 ct yellow gold with diamond-paved dial, fluted bezel and a President bezel.
This dial features 18 baguette-cut, rainbow-colored sapphires. 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 Day-Date 36.
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 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.
