In just 500 days, the world’s gaze will turn to the UK as the lights go up on the opening ceremony of the 2012 Olympic Games.

A giant Omega clock will be unveiled at Trafalgar Square on Monday, March 14, which will tick over when the 2012 Olympic Games 500-days-to-go mark arrives on Tuesday.

The London 2012 countdown clock will be 6.5 meters high and 5.5m wide, and weighs nearly five tonnes, The Telegraph reported.
