Why is the clock chip time inaccurate?

Inaccurate clock time is the greatest possible quartz crystal performance is poor, to repair quartz electronic watch to buy back a replacement can usually solve the problem, welding pay attention to the soldering iron end ground or unplug the soldering iron power, so as not to hurt the motherboard due to static electricity.
