This watch was specially made in one example, for the Antiquorum Only Watch charity sale, and sold on September 22, 2005, lot 2. The Muonionalusta meteorite The Muonionalusta meteorite is a rare iron that was originally found in 1906 near Kiruna, Sweden. This beautiful meteorite is classified as a fine (IVA) Octahedrite, and has spectacular etch patterns. Muonionalusta is only rarely found on the meteorite market as the strewn field is within the Arctic Circle, making searching for it very difficult. The total known weight of Muonionalusta is unknown, and until recently, most have been locked up in Museum collections, with very little in private hands. Iron meteorites are composed primarily of various alloys of iron and nickel, and are derived from molten planetary cores that were broken apart billions of years ago. The crystalline patterns within Meteorites are known as "Windmanstatten patterns". These patterns can only form in the vacuum of space where the molten pieces of planetary cores come into contact with very few molecules to which they can transfer their heat and thereby cool. The large metallic crystals characteristic of meteorites require literally millions of years of cooling to form from a molten planetary core fragment. It has been estimated that it took about 1000 years for these molten pieces of planetary core to cool by just 1 degree celsius! In addition to its technical qualities, the T21 represents a conversation piece that inevitably leads to deep and fascinating discussions and, on an even simpler level, inspires dreams.
