The sunray finish provides subtle light reflections on many dials of the Oyster Perpetual collection. This is due to the skillful brushing technique that creates grooves from the center of the dial to the outside. The light is evenly diffused along each engraving, creating a characteristic glow that moves slightly with the position of the wrist.
Once the sunray finish is complete, the color is applied to the dial by physical vapor deposition or electroplating. A light coat of varnish completes the final look of the dial.

Platinum, the most sublime metal, is rare and precious, and its silvery whiteness and brilliant luster are very impressive. As one of the densest and heaviest metals in the world, platinum has unique chemical and physical properties, including outstanding corrosion resistance. On the other hand, it also possesses contradictory properties of being soft, flexible, and malleable, making it extremely difficult to machine and polish, requiring an extremely high level of skill. Rolex usually uses 950 platinum. It is an alloy containing 950‰ (parts per thousand) of platinum, carefully crafted by Rolex's master metalworkers. The finest metals for the finest watches.
