alarm operations. When the Vibration Alarm is turned on, these expressions should
be understood to mean “causes the watch to vibrate”.

Watches with a metal band may produce a noise when a vibration operation
is performed. This is due to vibration of the metal band, and does not indicate
malfunction of the watch.
