The Suunto Core Black Outdoor Watch is extremely tough and features a large positive screen and backlight designed to be more visible in poor light conditions.

The Suunto Core is used by security forces worldwide needing a reliable partner with all the key features. It has a large 50-mm face giving you a great view of your key data and behind the clean face the Core has an impressive array of features from Altimeter, Barometer and Compass (ABC) to depth meter; it shows sunrise/sunset times and hosts a range of alarms.

The Suunto Core will alert you to sudden changes in barometric pressure with the weather-trend indicator and Storm Alarm, one of several intelligent features that can help you make better decisions.

The Sunto Core pressure gauge operates in four distinct modes, including an automatic setting that senses your movement or lack of it, switching between altimeter and barometer accordingly. The compass features a rotating bezel for traditional use and a one-touch function that allows you to sight, lock on to and follow a bearing. Daily functions include dual time, date, alarm, sports chronograph and predicted times for sunrise and sunset.

Dimensions: Width 50 mm, Depth 14 mm, Weight 66 grams.

Features

Altimeter

Accurate to 30,000 feet, the Suunto Core altimeter is a valuable tool for mountaineering, back-country skiing and wilderness travel. It displays your current elevation, shows how far you’ve climbed or descended and records your entire session for later analysis.

If you’re on or near an obvious feature (like a ridge, trail or creek), you can use your current elevation to find your position on a topographic map. If you plan on climbing a slope to a certain elevation and then traversing, an altimeter is an ideal tool for staying on course.

You can also use elevation to gauge your progress. The Suunto Core displays elevation gained and lost between a given point (a trailhead or belay station) and your current position.

Simplifying altimeter use, the Suunto Core includes a unique start-from-zero function that eliminates the need for entering a reference altitude. With a single push of a button, the altimeter will begin tracking your ascent and descent.

Barometer

The Suunto Core barometer measures and records air pressure to help you predict changing conditions, from sunny skies to hair-bending electrical storms.

When you’re hiking in a canyon or dense forest without views of the horizon, a barometer can 'see' into the distance, keeping you posted of changes in air pressure that can lead to bad weather. Even at home, the Suunto Core barometer looks beyond office walls, skyscrapers and nearby hills to help you plan ahead for upcoming ventures.

Auto Altimeter/Barometer

An altimeter measures air pressure to determine altitude, while a barometer measures air pressure to determine barometric pressure. If you leave your watch in altimeter mode while hanging out at camp, an incoming low-pressure front will read as a gain in altitude. Thus, it’s important to choose the right mode for your activity: altimeter for climbing and barometer for hanging out at camp. The Suunto Core makes it easy to manually choose the proper mode for your activity.

The Suunto Core also features an automatic Altimeter/Barometer mode that senses movement or the lack of it, switching between altimeter and barometer accordingly. When you’re climbing, it records changes in elevation. And when you stop to rest, it records changes in barometric pressure. A drop in air pressure while you’re sleeping under the stars will be recorded for what it really is - a change in barometric pressure, not altitude.
