Download an app compatible with your smartphone from an app store.
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.
Consult an authorized service center.
Protective stickers

the protective stickers and the parts, which may result in a skin rash and/or
