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

Be sure to remove any protective stickers that may be on your watch (case back,
