CHARACTERISTICS OF A MECHANICAL WATCH
. This mechanical watch operates using power obtained from a mainspring.
2. While loss/gain of a quartz watch is indicated by a monthly or annual rate, accuracy of a
mechanical watch is normally indicated by a daily rate (loss/gain per day).
3. Normal usage accuracy of a mechanical watch varies according to conditions of use (time
period that the watch is worn on the wrist, temperature environment, hand movement, and
winding state of the mainspring).
4. When the watch is affected by strong magnetism, it temporarily gains or loses time. If the
watch encounters a strong magnetic field, the parts of the watch may be magnetized. In this
case, repairs such as removal of magnetism are required.
