I have made an innumerable number of house calls over the last thirty two years because of this myth.
Pendulum wall clock has two winding holes.
If a clock does not strike a gong on the hour it is technically called a timepiece.
Windup clocks and keys clocks that require actual winding will have anywhere from one to three winding holes on the body of the clock often in the back facing.
Generally speaking if the clock has a single hole that hole controls the main time spring.
The hole on the right is used to power the time train and make the clock keep time.
Timepieces have only one winding hole in the face because they do nothing but tell time.
If your clock has two winding pegs the left one typically works the strike or chime while the right wind manages the clock s timekeeping.
A clock that strikes on the hour has two winding holes one for keeping time and one for striking.
For clocks with hanging weights raise the weights using the crank.
Wind the other one or two winding points the same way if your clock chimes on the hour or quarter hour.
If there is one hole it is a time only clock.
Clocks with three winding arbours chime on the quarter hour making a musical tone.
Winding the arbor in this hole will give the clock power to keep time.
It is not harmful to wind the clock more often.
This is a time and strike clock.
Turn the key clockwise until the spring becomes tight and will not turn further.
To prevent over winding your cables allow the entire pulley to be visible under the face of the clock.
The hole on the left is used to power the strike train which make the clock strike at the top of the hour.
Winding holes in clock faces.
I have set up thousands of clocks on outside walls and have never heard a complaint from a single customer that it has caused any kind of problem.
Most clocks are 8 day clocks which only need to be wound once a week.
You must lift the weight when winding a chain driven floor clock.
If your clock is cable driven you will wind all three weights with a crank key.
If there are two holes one is for the time spring and one is for the hourly chime.
Insert the winding key into the holes located in the dial face.
Depending upon the model of your clock there can be 1 2 or 3 winding key holes.
