We’ve talked about ABC watches extensively in previous articles and also recommended them as some of our top watch picks in our buyer’s guides for best watches for skiing and best hiking watches but this article is dedicated exclusively to ABC watches.

This class of watch is an ideal choice for anyone into adventure sports, camping, or high-altitude outdoor use where having a watch with an altimeter, barometer, and compass is most useful. Many of these watches also include other weather-related data and tools that come in handy if you are in remote areas.  

For example, the solar-powered Garmin Fenix 6X  features a pulse Ox sensor that estimates your blood oxygen saturation levels, color topographic maps and GPS. All these tools on your wrist, in addition to the ABC features, make it one of the most impressive outdoor watches on the market. 

Quick Recommendations

We’ve included a more detailed review below, along with several other watches we consider the best ABC watches of 2021. We’ve included a wide array of choices below from diverse price points, functions, brands, and technologies. If you’re shopping for your next ABC watch, read on.

The altimeter on ABC watches makes them a top pick for mountain sports.

What is an ABC watch?

Before proceeding to this year’s best ABC watches, let’s first discuss what these watches are about, focusing on their functions and price points.

All of the watches we’re featuring below have the ABC feature. To better understand these functions, here is a breakdown of all three factors: an altimeter is a feature that measures altitude, the barometer measures air pressure and helps alert you of changing weather, and a compass used for navigation. ABC watches are made for adventure and are designed to endure extreme temperatures. We also looked for watches with large display screens that are easy to read and dials with excellent luminosity for low-light or nighttime.

The big question is: is an ABC watch for you? If you’re into adventure gear and do a lot of outdoor sports and activities like hiking, mountain climbing, ultra-running, or even hunting, an ABC watch would be a joy to use. You do not have to use separate devices for measuring the essentials—they are all in one device. The smartwatches that have these features will also allow you to connect the data using your smartphone.

Best Altimeter (ABC) Watches

Garmin Fenix 6X Pro Solar – Top Pick

Garmin fenix 6X Pro Solar

Garmin is a market leader when it comes to multi-functional smartwatches, and the most recent generation Fenix 6X Pro Solar exceeds our expectation of previous reiterations of the Fenix series.

One of the biggest announcements in 2020 was Garmin’s new line of solar-powered watches including this Fenix model.  As for battery life, the Fenix 6X Pro Solar gives up to 21 days of battery life in smartwatch mode and up to 80 days in battery saver mode.

Apart from build quality and solar, the features are where the Fenix excels. Apart from standard ABC functions that include an altimeter for elevation data, a barometer to monitor the weather, and a three-axis electronic compass you get Garmin’s “altitude acclimation”, which adjusts your pulse oximeter reading, respiration rate, and resting heart rate correctly based on your current altitude.

Apart from that, the Fenix 6X comes with “PacePro” training program and health tracking that includes Pulse OX monitoring and sleep tracking. It also has TOPO maps and 2,000+ ski maps, backcountry ski, and trail routing for hikers and trail runners. 

The Fenix 6X Pro is the latest and greatest from Garmin and it is priced accordingly. If you don’t see spending this much on a watch,  check out the previous model, the Fenix 5X Plus that we recommended below. The Fenix 5X comes with tons of features at a more affordable price although you’ll get less memory and it lacks solar power.

Moving on to a well-known sports watch brand that continues to produce excellent products at relatively affordable prices. This Casio Pro-Trek watch is a solar-powered (battery-powered, and is recharged by a solar panel) ABC watch that has the Triple Sensor Version 3 engine. According to Casio, this model has a 95% smaller direction sensor, as well as a “90% reduction in sensor power consumption compared to previous models.” This is also more accurate and energy-efficient.

There are three big buttons on the right side of the watch where users can easily access the ABC features. The barometer of this model has what Casio calls the Barometric Pressure Tendency Alarm, which gives alert to the user when there are changes in pressure.

See a comprehensive review of the watch below.

This watch has a Super Illuminator LCD with backlight and afterglow, a stopwatch and countdown timer, world time in 48 cities, an auto-calendar until the year 2099. The battery life is exceptional as well: it can last for nine months on a full charge without further exposure to light. Those who will use this watch at low temperatures will also be able to enjoy its resistance up to -10C (14F).

Another big name in outdoor and ABC watches is Suunto, a Finnish company that has been making watches since 1936. The word “Suunto” means “direction,” which is what the company has always been known for: accurate compasses.

The Suunto Core line was first released in 2007. These sports watches boast of ABC features that have weather information—the best watch for outdoor sports and activities.

Some of the key features include a weather graph with preset sunrise and sunset times (for more than 400 locations), a storm alarm, and multiple dates and time functions. Those who will use this watch for snorkeling would also be able to use the depth meter for dives.

One of the features that have received mixed reviews is the battery life. Some say that it lasted them a year before replacement, while others claim that their batteries only lasted two weeks. Take note that when it comes to watches like these, the battery life will really differ—it will always depend on the features being used. If you want a more powerful battery life, however, you can also check out other Suunto models, which brings us to our next item.

Suunto has an app called Movescount that will allow users to easily integrate their Suunto watch to their smartphone. This connectivity will allow you to customize your watch using the phone, use the phone as a second watch display, discover new routes, and upload your progress and share your activity instantly.

Here’s another Casio, but this time it’s the G-Shock, which is one of the most trusted outdoor watches today. There are so many models to choose from, so for this article, we’re featuring one of the brand’s best ABC watches: The G-Shock Mudmaster.

The Mudmaster is an excellent watch for those who are doing adventure sports. As the name suggests, this watch was built for thosewhose work takes it into areas where piles of rubble, dirt, and debris are present.”

The Fenix 5x Plus is the previous generation of the Fenix line that has since been outdone by its new sibling, the Fenix 6 mentioned above. However, even though it’s not the latest, it’s still a very solid watch and great value now that the pricing has come down since it originally launched. 

One of the best features of the Fenix 5X Plus is the Pulse Ox Acclimation sensor, which estimates your blood oxygen saturation levels. This would come in handy for those who are on high altitudes. You will also be able to estimate your heart rate.

The navigation features are exceptional as well. This watch has a mapping system that allows the user to track their location, and find the best routes and paths. If you’re a runner or cyclist, these are some of the things that will maximize your workout.

Another Garmin watch of the same price range that you can check out is the Garmin Tactix Charlie.

Both this and the Fenix 5x are excellent for fitness, having features like tracking (steps, distance, and calories burned), but the Charlie is being marketed as a watch for field ops and tactical operations, as the name suggests.

One unique feature of the Tactix Charlie is the night vision mode, a feature that can change the backlight that will allow the user to use night vision goggles.

The only key feature difference between the Garmin Tactix Charlie and the Fenix 5x is the Charlie has a night vision mode. This is a feature that alters the backlight to make it easier to use with Night vision goggles.

Suunto 9 Baro

The 9 Baro is a premium model in the Suunto smartwatch line that the brand itself markets as an “Ultra-endurance GPS watch”. 

The barometer (thus the name) is where the Baro excels. The watch merges GPS data with barometric altitude information to provide advanced features including outdoor insights including sea level air pressure and has a storm tracker and air pressure alert – an alarm that will notify you of dramatic drops in barometric pressure (4 hPa+ within 3 hours).

The digital compass is tilt-compensated, meaning you don’t have to hold your wrist totally level to get an accurate reading.

For athletes, the Baro 9 offers tracking for an impressive 80 different sports modes. Apart from standard fitness tracking you’d expect no a premium smartwatch, it has advanced features for pace, heart rate graphs, and useful recovery metrics for serious athletes that include peak training effect (PTE) and excess post-exercise oxygen consumption (EPOC).

The Baro is specifically designed to be extra tough for the most arduous training, it would be a good pick for a triathlon or trail runner to get full use out of the performance metrics.

The Baro’s GPS is accurate and performs well. It also has three battery modes (Performance, Endurance, and Ultra) to track GPS from 25 hours to up to 170 hours of recording time.
