Fluted bezel
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 platinum on this Day-Date 36.
Ice-Blue Dial
The ice-blue dial is the discreet and exclusive signature of a Rolex platinum watch. Rolex uses platinum, the noblest of metals, for the finest of watches. This exclusive dial colour can be found only on the Day-Date, the Cosmograph Daytona and the Perpetual 1908.
Platinum
Rare and precious, platinum is striking for its silvery whiteness and vibrant luminosity. It is among the densest and heaviest metals in the world, distinguished by unique chemical and physical properties such as exceptional corrosion resistance. Paradoxically, it is also soft, elastic and highly malleable, which makes machining and polishing especially difficult, demanding an extremely high degree of skill. Rolex always uses 950 platinum, an alloy consisting of 950‰ (thousandths) platinum, painstakingly crafted in-house by the fine metalworkers at Rolex. The noblest of metals for the finest of watches.Model Availability
