If you're even vaguely familiar with Omega, you'll know the watchmaker is quite partial to a limited edition, especially for an anniversary. But hold your collective sighs, because this new trio of limited editions is well worth a proper look. Sixty years ago, in 1957, Omega released three watches that changed its fortunes forever. Moving away from the slender, dressy designs typical of the watchmaker, Omega launched a triple threat line-up with a sportier, chunkier aesthetic. Those three watches were the Speedmaster, Railmaster and the Seamaster 300.
