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.
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.

not to expose a watch with this rating to any type of moisture.
