Many different types of clocks are available, from grandfather and cuckoo to digital and computer clocks. Older clocks often have personal, as well as financial value. Although the personal value always exists, the financial value decreases if the old clock isn't working. Knowing the components of a clock will help you fix it. If you're uncomfortable working with small parts, consider taking your clock to a professional clock repairer. Bear in mind that not all clocks can be repaired.
Check to see if the clock needs to be wound before taking the clock apart. There are several different methods used to wind an old clock and the one you use depends on the type of clock you have. A general rule is that the number of gears determines the number of points to wind. For example, if there is only one winding point, there is only one set of gears. The way to determine this is to look at the dial of the clock where there are holes for a key. The number of holes on the clock represents the number of windings needed.
Look where the hands of the clock are. If both hands of the clock are stuck together or touching, this can cause your clock to malfunction. Carefully push the hour hand toward the top in a forward motion. This may be enough to release the jam, which prevented the clock from working. Bend the second hand slightly so that the hour and second hands pass by each other smoothly. The hands shouldn't touch the glass. Use the same technique to manipulate them just a bit so both the second, minute and hour hands don't clash.
Adjust the angle of the clock if it has been recently moved from one location to another. This can correct any imbalance and set the clock working again.
