Meteorite Iron meteorites are composed primarily of alloys of iron and nickel and are derived from molten planetary cores, which broke 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 is a conversation piece.

Antoine Preziuso After a conversation with Antoine Preziuso, it is evident that he is fundamentally at ease with himself, yet constantly in pursuit of fresh challenges. Born in Geneva in 1957 and brought up in the world of horology, Antoine Preziuso followed in the footsteps of the Genevan ?Cabinotiers? whose creations embodied talent and challenge. He acquired a thorough knowledge of horological history while restoring some of the most prestigious collectors? timepieces. With this technical experience, his Swiss exactitude and the aesthetic awareness inherited from his Italian ancestors, Antoine Preziuso launched his own brand in 1990. Whether working in collaboration with a select handful of famous brands or producing exclusive and often ?one of a kind? models under his own name, Antoine Preziuso follows his creative instincts.
