you're sitting for a long time, the watch would remind you every
hour to walk around for a break.

If the watch detects no enough activities or steps during the set
time period, the sedentary reminder function will be enabled, and
the watch will then remind you every one hour.

according to your needs. Up to 5 alarms can be set (The alarm will
only give a reminder when the set time is more than 2 minutes).
