8) Photosensitive eyeglasses
The watch digital display can become difficult to read
clearly when wearing photosensitive eyeglasses or
sunglasses such as ski goggles and tinted fishing
glasses. This problem can be corrected by turning
your wrist slightly to change the angle between the eye
and the watch providing a clear view of the display.
9) Keep your watch clean
Wipe off any water and moisture that adheres to the
case, glass and band with a soft, clean cloth. Any
dirt left on the case or band may cause skin rash. A
watchband will easily become soiled with dust and
perspiration because it is in direct contact with the
skin. Even a stainless or gold-plated band may begin
to corrode if it has not been cleaned for a long period
of time. Mesh bands, because the meshes are very
fine, will lose their particular “flexibility” if they are
left soiled for a long time.
Metal watchbands are usually washed with a brush in
mild, soapy water and wiped with a soft, absorbent
cloth to make sure all water is removed. Pay attention
to prevent any water from getting inside your watch
when the band is washed.
10) Periodic inspection
Getting your watch checked once every year or two
is recommended to ensure long use and trouble-free
operation.
11) Watch bands
Metal bands: Metal watch bands can be cleaned
with a toothbrush, soap and water.
Leather bands: Wipe off the front side of the band
with a soft dry cloth, and remove stains on the back
side of the band with a cloth moistened with alcohol.
Plastic or rubber bands: Wash in water. (Avoid using
solvents as they may cause the band to dissolve.)
12) Be sure to keep the batteries out of reach of
infants and small children. Should accidental
ingestion occur, consult a doctor at once.
