More than 1 million years ago, north of the Arctic Circle, the dial for this watch struck the Earth. The Muonionalusta meteorite was first discovered west of the border between Sweden and Finland in 1906 near the village of Kitkiöjärvi. It is believed to be more than 4.5 billion years old--one of the oldest known meteorites to have ever hit the planet. It has witnessed the rise and fall of four Ice Ages. Talk about history on your wrist.
