The dark anthracite color of this limited edition is achieved through a sophisticated electroplating process that preserves the original texture and patterning of the 4.5 billion-year-old Muonionalusta meteorite from which the dial is crafted. Before entering Earth’s atmosphere, the meteorite cooled in the vacuum of space, resulting in an exquisite configuration of geometric shapes known as the Widmanstätten pattern. This pattern exists only in nature and cannot be replicated. Every dial is unique.
