Note: When purchasing a crank, make sure the length of the shaft is sufficient to raise the crank above the level of the clock hands, so you can turn it 360º without damaging them. [2] X Research source Some manufacturers sell keys in a numbered scale, rather than by shaft width. However, there is no single industry-wide scale, so referring to the exact millimeter size is recommended. [3] X Research source
If you cannot turn the key easily, or you do not see a weight moving, check to see if one of the weights is already at the top. If one or more of the chimes is turned off, the weight responsible for timing that chime will not fall, and does not need to be wound. The weights are typically located above the pendulum. You may or may not need to open the lowercase in order to see them.
There are some clocks that can safely have their minute hand turned counterclockwise, but do not risk it unless you are certain. If the minute hand “resists” attempts to move it clockwise, and can move smoothly counterclockwise, you may have an unusual model that should be adjusted counterclockwise. [6] X Research source If your clock is running too fast or too slow, find the knob or nut at the bottom of the swinging pendulum. Tighten it clockwise in order to slow the clock down, or loosen it counterclockwise to speed it up.
If you cannot find either a chain or a winding hole in the clock face, ask someone to help you look, or consult a professional clockmaker or clock repair shop.
Pull on the chain next to a weight, never the chain the weight is attached to. It does not matter which weight you wind first.
Typically, the center weight controls the clock’s timekeeping. If other weights are present, they control the hour strike, or the quarter-hour chime.
A nut on the bottom of the pendulum can be tightened to slow the clock down, or loosened to speed it up. Adjust this if you find yourself adjusting the time every week or two.
