With the Garmin Fenix 6 Sapphire, you can navigate in challenging conditions since the GPS is supplemented by other global navigation satellite systems. The watch comes pre-loaded with topo maps, including maps of ski resorts.

And if you’re acclimating to altitude, the Pulse Ox sensor tracks your blood oxygen levels so you can always stay in the safe zone.

When you’re not out in the backcountry, the Garmin Fenix 5X Sapphire can connect to WiFi for notifications from your smartphone. It can also store or stream music to play via Bluetooth headphones when you’re walking around town or training for your next adventure.

If you need your mountaineering watch to last for a prolonged period without requiring charging, the Coros Vertix is an excellent choice for long expeditions. The battery lasts for 45 days in regular mode, and if you turn on the full GPS, it still lasts for 60 hours, which is impressive for a mountaineering watch. The watch measures your blood oxygen level as well as your altitude which can help you track how your body is acclimating to high altitude.

The Coros Vertix is operated via a knob and buttons, which are easy to use when wearing gloves in extreme weather. The sapphire glass face is diamond-hard to resist scratches, even in the harshest conditions.




All mountaineering watches should have an altimeter to measure your altitude, a barometer to track barometric pressure changes (which can determine both altitude and impending weather), and a compass for navigation.

Beyond those basic features, you need to decide whether you want to invest in a watch that can do things such as help you train and connect to a smartphone. The Appalachian Mountain Club gives some insight into the important features of a mountaineering watch.



Are you planning to depend on your mountaineering watch for navigation? While many mountaineering watches have GPS capabilities, some only include a compass for navigation. If you don’t have a separate GPS unit (or don’t want to carry one on your expedition), you should choose a mountaineering watch that includes a GPS. Some watches also include topo maps, which can be useful in planning and finding routes.



You definitely don’t want your watch battery to die when you’re depending on it in the backcountry, so battery life is an important consideration when choosing a mountaineering watch. The use of GPS drains battery life, but most watches allow you to turn off the GPS when it’s not needed to save power.

Also, the Casio watches are solar-powered, which is a good option if you don’t want to have to worry about your battery life on long trips.
