Magnetic resistance (Magnetic influence)

Affected by nearby magnetism, a watch may temporarily gain or lose time or stop operating.

Indication on the case back

Conditions of use

Certified level

mark JIS-1_b

Keep the watch more than 5 cm away from magnetic products.

4,800 A/m

mark JIS-2_b

Keep the watch more than 1 cm away from magnetic products.

16,000 A/m

MAGNETIC RESISTANT 40000A/m

The watch can maintain its performance in most cases where it is brought close to (at least 1 cm spaced from) magnetic products not only in normal daily life circumstances but also in a special work environment.

40,000 A/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.
