Nice video. Even better to see one of our strike clocks working in Canada. The John Smith comany is still going and still in the Smith family.

how are the pendulum oscillations sustained?
i meant that the oscillations may die out because of friction, how is this prevented?

Good question - the escapement mechanism is designed to "kick" the pendulum on each stroke. The force to do this comes from the suspended weight.

We should have a clock like this at Morrisons. Instead of our 2 face silent electric clocks these are huge clock tower face style dials I would prefer the 4 face clock on this video!
