5. Temperature
Avoid exposing the watch to direct sunlight or leaving it in extremely hot or cold
locations for a long period of time.
• This will cause malfunctioning and shorten the life of the battery.
• This may cause your watch to gain or lose time and affect its other functions.

• This watch will withstand the bumps and jars normally incurred in daily use
and while playing such non-contact sports as golf and catchball.
• Dropping the watch on the floor or otherwise imparting severe shock to it may
cause malfunctioning or damage.

This watch is antimagnetic up to 60 gauss and not affected by the magnetic
fields produced by ordinary household electric appliances. If used in the
immediate vicinity of strong magnetism, however, the watch's functions may
temporarily be affected.
