Magnetism
• The hands of analog and combination (analog-digital) watches are moved by a motor
that uses magnetic force. When such a watch is close to a device (audio speakers,
magnetic necklace, cell phone, etc.) that emits strong magnetism, the magnetism can
cause timekeeping to slow down, speed up, or stop, resulting in the incorrect time
being displayed.
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.
Chemicals
• Do not allow the watch to come into contact with thinner, gasoline, solvents, oils, or
fats, or with any cleaners, adhesives, paints, medicines, or cosmetics that contain
such ingredients. Doing so can cause discoloration of or damage to the case, resin
band, leather band, and other parts.
