1. th is mechanical watch operates using power obtained from a mainspring.

2. W hile loss/gain of a quartz watch is indicated by a monthly or annual rate, accuracy of a m echanical watch is normally indicated by a daily rate (loss/gain per day). 3. N ormal usage accuracy of a mechanical watch varies according to conditions of use (time p eriod that the watch is worn on the wrist, temperature environment, hand movement, and w inding state of the mainspring). 4. W hen the watch is affected by strong magnetism, it temporarily gains or loses time. if the w atch encounters a strong magnetic field, the parts of the watch may be magnetized. in this c ase, repairs such as removal of magnetism are required.
