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.

MINT GREEN DIAL

The sunray finish on Rolex dials is a predominant method in watchmaking of achieving pure metallic colour 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 colour is added to the prepared dial. Sometimes colours such as champagne are achieved through electroplating with more than half a dozen different metals.

WHITE ROLESOR

Gold is coveted for its lustre and nobility. Steel reinforces strength and reliability. Together, they harmoniously combine the best of their properties. A true Rolex signature, Rolesor has featured on Rolex models since the early 1930s, and was trademarked as a name in 1933. It is one of the prominent pillars of the Oyster collection.
