Rolex Oyster 40 mm Eisenkiesel Set With Diamonds Dial 18 kt Everose Gold President, Semi-Circular Three-Piece Links m228235-0045

The Oyster Perpetual Day-Date 40 in 18 kt Everose gold with an Eisenkiesel, diamond-set dial, fluted bezel and a President bracelet.

This dial features 10 baguette-cut diamonds. The Oyster Perpetual Day-Date 40 is presented with a dial made from eisenkiesel, a deep brown decorative stone used by the brand for the first time in 2021.

Eisenkiesel is an iron-oxide, delicately veined quartz. The stone discs destined for the dials are cut from a block of raw material. Only those whose colour and structure fully satisfy the brand’s exacting aesthetic requirements are selected. They will grace the dial of a Rolex watch, conferring it with a unique personality.

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.
