Eisenkiesel dial
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.
