The altimeter measures up to 9000m. It is perfect for all activities where it is important to know your altitude and your climbing and descent speeds. The Suunto Core altimeter measures differences in altitude to follow your overall progress on a climb. The log records all your elevation changes between start and end times, enabling you to analyse your activity by drawing graphs, once you get home.


The Suunto Core displays current pressure at sea level in the form of a detailed graph showing the values recorded for the last 24 hours at an interval of 30 minutes. The weather trend indicator is a useful feature that allows you to quickly know approaching weather conditions. The storm alarm informs you of any sudden drop in air pressure, which may precede severe weather conditions.

Alti/Baro automatic tilting

The Suunto Core has an automatic Alti/Baro tilt, which detects movement or absence of movement, going from altimeter mode to barometer mode, respectively. It records altitude changes when climbing. And when you stop to rest, it records changes in barometric pressure. Any fall in pressure that occurs while you sleep outdoors will be accurately interpreted.


The digital compass displays the North and cardinal and semi-cardinal points. By adjusting the declination, you can correct the difference between geographic and magnetic North. You can also set the compass to follow a given bearing, which allows you to follow a chosen direction in the field.

Depth gauge

Designed for free diving, the Suunto Core depth gauge tells you the depth you have reached and the maximum depth reached during your dive. The maximum depth of the device is 10m.


Watch features include time, dual time, date, alarm, stopwatch, countdown timer and predicted times for sunrise and sunset for over 400 places worldwide.
