How Omega's Speedmaster became the unofficial 'space watch' is quite an intriguing tale, and one that has paid dividends for the Swiss watchmaker since 1962. You can read more about the origins of space-going timepiece in this brief history here.

Half a century later, Omega recreated a handful of those gold watches - producing just over 1,000 examples - and, of course, Hollywood icon-turned-philanthropist George Clooney owns one of them.
