Mechanical Clock Model
from Japan

Tide a piece of string.

The function of it is like the Mainspring of a wrist watch.

The washer is not included. However, the washer make sure the string will not come out.

There is still one parts not included ... ... a heavy load.

By the gravity, the heavy load generate a force to pull the Wheel and make the clock run.

When I have a heavy load, I will record a movie showing how this mechanical clock runs.

Come back later !
