Best mountaineering watches

For mountain adventurers that thrive under pressure (and air pressure), a good mountaineering watch isn’t enough. Only the best hiking watches will do for those who take their high-altitude hijinx seriously.

The differences between a good hiking watch and the best mountaineering watch options out there are subtle but important. A basic altimeter watch might offer an altimeter/barometer/compass combination, but the overall accuracy might be lacking. And while some outdoor watches offer basic features that are good enough for casual mountaineers, the best mountaineering watches go above and beyond with loads of smart features and accurate GPS tracking wherever you may roam.

When separating ordinary mountaineering watches from extraordinary ones, look for key specs like an intuitive digital compass, the lengthy battery life in both GPS mode and power-saving mode, numerous hiking features to choose from, advanced features for alpine climbing, and the best GPS accuracy possible.

We’ve tested tens of candidates for the best mountaineering watches, from the best Casio watches to the top Garmin watches and beyond, to curate our in-depth list of the 8 Best Mountaineering Watches Available In 2021.

Only the best watches will do for your outdoor adventures, and they’re waiting for you below.

Frequently Asked Questions

What sort of battery life should I expect from the best GPS watches?

The GPS functionality included in the top GPS watches will drain your battery life quicker than any of the other included features. GPS navigation requires a ton of juice, as do the altimeter, barometer, and compass readings you’ll take along the way. Whether your smartwatch has a solar-powered battery or not, you should expect to recharge it every 12-18 hours (with music) or so when using your GPS function. ABC watches without GPS functionality will last longer, as will GPS watches when placed into battery-saving mode. Some modern altimeter watches can last a week or so on a single charge without using GPS. That’s great battery life when it comes to smartwatches and hiking watches.

Which brands make the best altimeter watches and hiking watches?

For those in the watch market for a barometric altimeter timepiece that provides accurate barometric pressure readings, the risk of securing an uncomfortable watch with a dodgy interface is one not worth taking. You deserve a durable watch with all the extra features that put other watches out of sight and out of mind.

Mountaineers like you should look to outdoor watch offerings from Garmin, Suunto, Casio, and Coros first and foremost. These four brands only traffic in high-quality watch materials such as sapphire glass and scratch-resistant mineral glass lens options, stainless steel bezel constructions, and stainless steel cases. They also promise unparalleled durability that rivals the toughest hiking gear out there. If you require a new watch for your mountain exploits, check these four watch brands out and you’re bound to find something worth your money.
