Magnetism
Though your watch normally is not affected by magnetism, very strong
magnetism (from medical equipment, etc.) should be avoided because it
can cause malfunction and damage to electronic components.
Though operation of your watch normally is not affected by magnetism, its
accuracy may be affected if the watch itself becomes magnetized. Also,
very strong magnetism (from medical equipment, etc.) should be avoided
because it can cause malfunction of the watch and damage to electronic
components.
Electrostatic Charge
Exposure to very strong electrostatic charge can cause the watch to display
the wrong time. Very strong electrostatic charge even can damage
electronic components.
Electrostatic charge can cause the display to go blank momentarily or
cause a rainbow effect on the display.
