Suunto Observer measures your vertical ascents and descents, as well as the total number of runs skied and shows all that easily with one press of a button. Its timeless design makes it wearable in any casual situation, and because of its moderate size and stylish design it is perfectly suitable for both men, as well as women.

Altimeter
Suunto Observer's altimeter has a range up to 9 000 m/29 500 ft with a 1 m/3 ft resolution. It features an altitude alarm as well as memory function for storing logs of your most exciting mountain adventures. The logbook allows you to record total and cumulative vertical ascents and descents, as well as the number of runs skied. The logbook data is quickly available during the activity with one button press.

Barometer
The Suunto Observer and its barometric functions provide you with valuable information for forecasting weather changes. Information on the present sea level pressure helps you read and understand the barometric pressure at high altitudes.

In addition to current barometric pressure and temperature, the barometer function of Suunto Observer gives pressure related data for the past four days: the first six hours in one hour intervals and after that in six hour intervals.

Alti/Baro lock
This unique feature allows you to use your Suunto Observer as a weather station, or an altimeter.

When Suunto Observer is used as an altimeter, the sea-level pressure reading is locked. When the altimeter function is activated, all pressure changes are interpreted as altitude changes, and the sea-level pressure reading displayed will not change, although the absolute pressure reading does.

When Suunto Observer is used as a weather station, the altitude reading is locked. When the barometer function is activated, all pressure changes are interpreted as weather changes, and the measured changes will therefore only affect the pressure reading in the barometer mode. These changes will not affect the altitude reading, thus enabling instant weather forecasts.

Compass
The compass shows the cardinal or half-cardinal point abbreviated and indicates the North with an arrow. The compass can be set to track a certain bearing, and graphically show the difference between it and the actual bearing. This is a valuable tool, when trying to get back on track after minor or major detours in the terrain. The declination adjustment function allows the user to correct the difference between true North and magnetic North.

Watch
Suunto Observer also has a calendar clock pre-programmed to the year 2089 with three daily alarms, a dual time display, and a stopwatch with lap and split time measurement. The stopwatch stores up to 99 laps and split times for one run. The time can either be shown in 12 or 24-hour format.
