One Winding Hole
Two Winding Holes
Three Winding Holes
This is a chiming clock. Not only will it keep time and strike at the top of the hour, but it will also chime on the quarter-hour. The hole in the middle, near the '6' powers the time train which makes the clock keep time. The hole to the right powers the quarter-hour chiming and the hole on the left powers the striking at the top of the hour.
The direction in which you need to turn the key or crank varies between different makes of clocks. However, it will be quickly evident with your clock as to which way is the correct direction to wind the clock. It you try winding the clock in the wrong direction, the key simply will not turn. Turning the key in the correct direction will produce a clicking sound. Continue until it will not wind any further.
