Before using this watch
Band adjustment
We recommend seeking the assistance of an experienced watch technician for sizing
of your watch. If adjustment is not done correctly, the bracelet may unexpectedly
become detached leading to loss of your watch or injury (excluding products
containing the band adjustment tool).
Consult an authorized service center. Other shops may charge for, or may not
provide, the service.
Protective stickers
Be sure to remove any protective stickers that may be on your watch (case back,
band, clasp, etc.). Otherwise, perspiration or moisture may enter the gaps between
the protective stickers and the parts, which may result in a skin rash and/or
corrosion of the metal parts.
