Due to the density of  Magnesium the AZ91 Alloy used for construction is one of the lightest used in watch manufacture. To achieve the whitish (well light grey) case colouring the case is treated by electro plasma oxidation. This treatment is not only for colouring but it does also improve the hardness and scratch resistance of the case along with increasing wear and corrosion resistance.
