For clocks with a cable driven movement wind the weights all the way up.
My windup wall clock doesnt windup anymore.
If both hands are stuck free the minute hand first then the hour hand.
Im fixing my old clock.
When done properly the wire or string should go through six chain links.
Try adjusting the level attitude of the clock each way a little.
Turn the key slowly and just a half turn at a time.
Bend the stuck hand slightly to clear the obstacle.
Gently move the hands with a finger to see if they are touching the dial the glass or each other.
Wind it up until it stops.
This is the basis for this clock myth that continues to cause concern in amateur horologists.
If you don t hear a ticking sound the clock s hands are probably stuck.
Do not try to force it to wind any further.
There might also be adjustments for this located near the top of the pendulum.
Secure the wire or string to prevent the chains from coming loose from the sprocket.
Although this doesn t sound too terrible a clock is meant to run at full throttle.
When you do wind your clock just make sure you have a tight fitting key and that it is inserted all the way.
