Temperature
■
Never leave the watch on the dashboard of a car, near a heater, or in • •
any other location that is subject to very high temperatures. Do not
leave the watch where it will be exposed to very low temperatures,
either. Temperature extremes can cause the watch to lose or gain
time, to stop, or otherwise malfunction.
Impact
■
Your watch is designed to withstand impact incurred during normal • •
daily use and light activity such as playing catch, tennis, etc. Dropping
the watch or otherwise subjecting it to strong impact, however, can
lead to malfunction. Note that watches with shock-resistant designs
(G-SHOCK, Baby-G, G-ms) can be worn while operating a chain saw
or engaging in other activities that generate strong vibration, or while
engaging in strenuous sports activities (motocross, etc.)
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,
and other parts.
