Rolex Day-Date 40 M228238-0042 technical specifications details

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 gold on this Day-Date 40.

White dial

Lacquer combines almost limitless freedom of colour with intensity and a smooth finish. The lacquering technique consists of successively depositing six thin layers of lacquer on a brass base plate. A colourless varnish is then applied to give the colour or shade all of its depth and shine. Once the varnish is dry, the surface of the dial is polished to magnify the colour; the dial is then ready to be pad printed and receive its appliques.

18 ct yellow gold

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.
