Sunrise and sunset alarms

The sunrise/sunset alarms in your Suunto 9 Peak Pro are adaptive alarms based on your location. Instead of setting a fixed time, you set the alarm for how much in advance you want to be alerted before the actual sunrise or sunset.

The sunrise and sunset times are determined via GPS, so your watch relies on the GPS data from the last time you used GPS.

To set sunset/sunrise alarms:

  1. From watch face, press the lower button or swipe up to scroll to Alarms and enter by pressing the middle button.
  2. Scroll to the alarm that you want to set and select by pressing the middle button.

  3. Set the desired hours and minutes prior to sunrise/sunset by scrolling up/down with the upper and lower buttons and confirming with the middle button.

  4. Press the middle button to confirm and exit.

A watch face is also available that shows sunrise and sunset times.


Sunrise and sunset times and alarms require a GPS fix. The times are blank until GPS data is available.
