THE 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, always in gold.

CHAMPAGNE COLOR DIAL

The sunray finish on Rolex dials is a predominant method in watchmaking of achieving pure metallic color dials such as shades of silver grey, rhodium or ruthenium. Silver-plating is mostly used as a base layer for the sunray finish, where further color is added to the prepared dial. Sometimes colors such as champagne are achieved through electroplating with more than half a dozen different metals.

18 KT YELLOW GOLD

By operating its own exclusive foundry, Rolex has the unrivalled ability to cast the highest quality 18 kt gold alloys. According to the proportion of silver, copper, platinum or palladium added, different types of 18 kt 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.
