Rolex Day-Date 40 Oyster 40 mm Everose gold Olive green dial M228235-0025

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.

OLIVE GREEN 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 EVEROSE GOLD

To preserve the beauty of its pink gold watches, Rolex created and patented an exclusive 18 kt pink gold alloy cast in its own foundry: Everose gold. Introduced in 2005, 18 kt Everose is used on all Rolex Oyster models in pink gold.
