    Hi
    I have several miniature 400 day clocks. Just been working out how far the pendulum travels. The pendulum radius is about 2 inches and they oscillate around 270 degrees. This works out at 4.5 inches per revolution. 10 revolutions per minute is 45 inches. In a day this is approximately 1 mile. So 365 miles a year. This would take me from London to Edinburgh in Scotland - all from a single winding of the spring. Amazing!!
    Just thought I’d share.

    Noticed a mistake - Meant to say that the diameter is 2 inches, not the radius. Maths remains the same
