Rolex Day-Date 40 Oyster 40 mm yellow gold White dial M228238-0042

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.

WHITE DIAL

The dial is the distinctive face of a Rolex watch, the feature most responsible for its identity and readability. Characterised by hour markers fashioned from 18 kt gold to prevent tarnishing, every Rolex dial is designed and manufactured in-house, largely by hand to ensure perfection.

18 KT YELLOW GOLD

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