Rolex Datejust Turn-O-Graph 36mm in Oystersteel and Yellow gold features a black dial

This Datejust Turn-O-Graph 36 in Oystersteel and Yellow gold features a black dial and an Oyster bracelet.

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 Datejust 36.

The sunray finish creates delicate light reflections on many dials in the Oyster Perpetual collection. It is obtained using masterful brushing techniques that create grooves running outwards from the centre of the dial.

Light is diffused consistently along each engraving, creating a characteristic subtle glow that moves depending on the position of the wrist. Once the sunray finish has been completed, the dial colour is applied using Physical Vapour Deposition or electroplating. A light coat of varnish gives the dial its final look.

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.

The Oyster bracelet is a perfect alchemy of form and function, aesthetics and technology, designed to be both robust and comfortable.

It is equipped with an Oysterclasp and the Easylink comfort extension link, also exclusive to Rolex. This ingenious system allows the wearer to increase the bracelet length by approximately 5 mm, providing additional comfort in any circumstance.
