it is brought close to (at least 1cm
spaced from) magnetic products

circumstances but also in a special

80,000A/m
A/m (ampere meter) is the International unit (SI unit) for indicating the magnetic field.
If the watch becomes magnetized and its accuracy deteriorates to an extent
exceeding the specified rate under normal use, the watch may need to be
demagnetized. In this case, you will be charged for demagnetization and
accuracy readjustment even if it happens within the guarantee period.
The reason why analogue quartz watch is affected by magnetism
It is because the built-in motor of the watch which harnesses magnetic power,
and external strong magnetism, affect each other to stop the motor or to
suppress the turn of the motor.
