Best Altimeter Watches Reviews

Updated May 16, 2023

Also known as ABC watches, these are wrist devices with features that go beyond standard time-telling. They are a great fit for athletes, sportives, outdoor adventurers, hikers, and people who work on wide areas of terrain. 

A watch that’s equipped with a basic altimeter, barometer, and compass is extremely useful when it comes to orientating in space, following a trail, or just monitoring the steps you’ve taken. Many are suitable for rugged outdoor activities. In addition, many of these advanced devices are designed to monitor fitness activities and athletic performance and can communicate with mobile devices using WiFi or Bluetooth. 

In search of the best altimeter watch, we reviewed some of the best products on the market that came with ABC sensors. Still, we also took under consideration other important features such as design, weight, durability, GPS module, and battery life. Garmin produces excellent GPS watches and we have two models listed in our guide. 

As you will see from our reviews below, the best ABC watch must be a combination of these features and a bit more.

1. Fenix 6 Premium ABC Watch


This outdoor sportwatch has GPS, and other navigation features that make it ideal for multiple outdoor sports. The crystal is protected by a rugged stainless steel bezel (the top ring on the watch that surrounds the crystal) and the watch is tested to U.S. military standards for thermal, shock and water resistance.

There are satellite navigation and tracking functions, along with a 3-axis compass and barometric altimeter.

The GPS combines with GLONASS and Galileo to track your position more accurately than GPS alone, meaning you can hike or trail ride in more challenging environments.

Activity features include enhanced wrist heart rate, built-in activity profiles, Vo2 Max estimates and more. The built-in activity profiles are for trail running, swimming, running, biking, hiking, rowing, skiing, golfing and more.  There’s also performance metrics and training load balance readings, advanced sleep monitoring and the ability to read altitude acclimation at high elevations. Use the watch to track your training load balance, training status, and running and cycling dynamics.

A great feature is the customizable power manager, where you can monitor how various settings and sensors impact battery life, allowing you to adjust to extend your battery life. The battery has four modes with different performance life depending how you use it: up to 14 days in smartwatch mode, up to 36 hours in GPS mode, up to 28 days in expedition GPS activity mode, and up to 48 days in battery saver watch mode.

The display is readable in sunlight and is “always on,” meaning you can easily check it while climbing or cycling. When paired with a compatible smartphone, you can receive notifications and use Garmin Pay™ contactless payments. Also when paired with a smartphone, the watch will sense an incident and send your location to emergency contacts.

Altimeter (ABC) Watch Buying Guide

Design & Size

The design of a wrist altimeter is built around durability and ease of use. As such, most ABC watches have a large display and a slim profile (where possible). In addition, the materials used are thought to be water and shock-resistant which is why you won’t find many luxurious designs in this category. 

However, this doesn’t mean the design of an ABC watch is not attractive. They can be accessorized with casual and sport outfits, which is why many users wear them every day.  


Barometer watches are designed to be comfortable so they must be lightweight (to not strain the wrist). Also, the materials used (silicon for the strap and reinforced polymer or stainless steel for the case) are durable, but lightweight. 

Overall, an altimeter watch must feel secure on the wrist and easy to use, regardless of the main interface (controls, touchscreen, or both). 


Given that an ABC watch is more of a sports-oriented device, it has to feature a durable and comfortable design (as we already discussed). Still, there are three important features that set these timepieces aside from the other products on the market: altimeter, barometer, compass. 


The altimeter is the feature that measures altitude and provides real-time data about elevation. It also monitors the ascend and descend as you move up or down. 

This is possible because the altimeter responds to air pressure. As such, the higher you go, the less air it is, and the closer to sea level, the more air pressure. This allows altimeter watches to follow altitude changes in increments of 3 ft (1m).


The barometer also works by measuring air pressure, but its job is to alert you about changes in the weather. The information read by the barometer in your watch is used by some of the gadgets on these devices, so you don’t have to do the interpretation yourself. 


The compass is used for navigation and, when paired with a GPS module, it can be quite accurate. 

GPS Altimeter Watches

The GPS module’s purpose on an ABC watch is twofold. First, it helps with navigation and keeping accurate track of your position on a given terrain. Second, the GPS is used by fitness monitoring apps to track distances and speed and calculate calories burnt, numbers of steps and more. 

Now, an altimeter watch doesn’t need a GPS module to function correctly, but it is highly recommended to find a product that’s equipped with such an item. It is quite useful for a wide array of applications.

Battery Life

Luckily, most modern ABC watches are equipped with a rechargeable lithium-ion battery that holds its ground even when you’re using the watch in GPS mode. However, most batteries don’t last more than 24h if WiFi or BT is heavily used. Also, ABC watches that use topographic maps for navigation, may last even less time. 

The secret to good battery life stands in how you use the watch. As such, if you don’t need to know the bearings of your location, it’s best to turn off the GPS and other consuming modules. In watch mode, the battery should last at least a few days.
