The Oyster Perpetual Day-Date 36 mm in 18 ct yellow gold with a turquoise, diamond-set dial, fluted bezel and a President bracelet.
This dial features hour markers in 18 ct gold, set with 32 diamonds, and a Roman VI and IX in 18 ct
gold, set with 24 diamonds. Only found in a few places on Earth, turquoise has been prized for thousands of years for its special hue. Rolex selects turquoise for the beauty of its structure and its characteristic, rare blue colour, because it marries perfectly with yellow and white gold. It is exclusively reserved for gold or platinum versions of the Day-Date 36. 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.
