Navigating the world of altimeter watches is a challenge. We have you covered! After evaluating over 40 models, we tested the top eight options side-by-side. Our experts summited mountains, hiked canyons, and lapped routes at local climbing crags to find the most accurate models, the most intuitive and easy to use interfaces, and the longest-lasting batteries. Each model features essential functions useful to outdoor enthusiasts: altimeter, barometer, digital compass, and standard timekeeper, while some offer a much more full range of functionality, including GPS and activity tracking. After three months of heavy use, testing, and meticulous note-taking, we created a comparative review of the ones that stole our hearts and our wrists. Whether you are looking for a model with the basics at a reasonable price or want to break the bank on the feature-laden, do-it-all watch, we cut through the nonsense to help you make the best decision.

Updated December 2018
With northern hemisphere summer in the rearview and winter on the horizon, we have updated this review to bring you the latest info on the altimeter market. We opted into the high-end market, grabbing the Garmin Fenix 5x Plus Sapphire, a real powerhouse of a watch with a price tag to match. On the other side of the cost spectrum, we also tested out the Casio Pathfinder PAG240B-2, an entry-level model that sticks with a basic set of ABC features. Our previous favorite, the Suunto Ambit3 Peak holds on to the top spot through it all.

Comfortable
High-quality and easy to use
Exceptionally accurate
Many great features, like GPS and a rechargeable battery
Chunkier profile
Limited battery life

The Suunto Ambit3 Peak remains our favorite model. The high-quality black and white display adds to the user-friendly interface of this watch. When using complex features, it's simple to transfer, view, and manage data on a computer as necessary. We like its ergonomic fit, along with the fact that our wrists didn't sweat much under the breathable band and watch face. The Ambit3 Peak's altimeter is also one of the most accurate tested.

Similar to GPS watches, this model doesn't boast a long battery life, although it is rechargeable. It's also more affordable than most GPS options and is frequently offered at a discount at online retailers. This beast is great for tracking altitude, but also includes tons of extra features we love, such as navigation, fitness tracking, and more.

Great battery life
Durable aluminum finish
Nice fit
Precise
Easy to use interface
Sub-par altitude and barometric graphs
Lacks GPS
Screen settings not adjustable

The Suunto Core Alu is a classic altimeter watch is designed to get the basics right. It tracks total ascent and descent and offers both barometer and altimeter graphs, a compass, and a reliable long-lasting battery. Don't be afraid to take this on a multi-day or multi-month mission.

It's not filled with as many features as the Garmin Fenix 5 Plus and doesn't include a GPS. We also wish that the altitude and barometer graphs were a little sleeker. Also, if you are looking for something even a little more affordable, opt for the traditional Core, which costs about $100 less. In spite of its drawbacks, we figure that if an altimeter watch is meant to do one thing well, its measure altitude, and that's what the Core Alu does.

Affordable
Simple & lightweight
Accurate
Functional
Lacks features and comfort
Lacks a compass
Unattractive
Poor quality display

The Casio SGW300-HB is a bare-bones altimeter watch that is by far the least expensive model we tested. It has basic time-telling functions and a dual-sensor that can track barometric pressure and altitude. Despite its price tag, we were surprised to see that it is still fairly accurate and provided a decent estimate of the altitude when calibrated regularly.

This utilitarian watch lacks sleek styling and an ergonomic fit. It is also less precise than other watches because the altitude reads in 20-foot increments. Because it doesn't come with navigation features like a compass or GPS, it's not a reliable way-finder in the backcountry. However, if you're in the market for a timepiece and would also like to know the barometric pressure and altitude every now and then, this easy-to-use, long-lasting Best Buy winner may be your best bet.

Best Features and Fitness Tracking


Garmin Fenix 5X Plus Sapphire


Greatest number of features
Exceptional display quality and graphs
Easy to use
Good battery life for a GPS watch
Extremely expensive
Heavy

The Garmin Fenix 5x Plus Sapphire is much, much more than an altimeter watch. It certainly includes all of the basic altimeter, barometer and compass functions, but it also offers fitness tracking features like a heart rate monitor, VO2 max calculator, pulse oximeter, and a huge array of activity tracking modes.

As a GPS-enabled watch, its battery life suffers, but it still lasts much longer than its closest feature-filled competitors, like the Suunto 9 Baro. Though you can easily recalibrate this watch, we found that it doesn't take much to throw off the altimeter. All in all, this watch earns a Top Pick award for its massive array of features for the fitness-tracking gear junky.

We took the Ambit3 Peak to the high mountain range of the Peruvian Andes. We ran  hiked  and backpacked over 150 miles with over 19 000 feet of vertical gain. Pictured here is Jared running out a downhill after summiting a 16 000 ft pass.

Analysis and Test Results


Over several months, we put each altimeter watch to the test. We took them around the western hemisphere — from Peru to Canada. To learn about each one, we tinkered endlessly and poured over the 15 to 70-some page user manuals to make sure we understood what the watches are capable of. We looked online to learn about any issues that needed to be tested and read about each watch from other independent reviewers. In addition, we tested each model side-by-side in a wide range of environments and activities. The chart below summarizes the comparative overall performance scores of each model.

After talking with mountain guides, ultra runners, hikers, and backpackers, we identified six key metrics to consider during testing; altimeter accuracy, battery life, ease of use and interface, the number and quality of features, display quality, and comfort. For each, we designed specific and objective tests and recorded our results below. We hope you find our comparison of the top altimeter watches helpful as you make your purchasing decision.


Value


We understand that sometimes pricepoint and value can be a critical factor in determining whether or not a certain product is right for you. One way we get at this is to compare price against a product's score. In addition, getting the most out of your altimeter watch requires an honest appraisal of what you will use it for and how often.

For the casual outdoor enthusiast who wants to know altitude at any given moment on an outdoor excursion, the base model Casio SGW-300H is a fine, affordable option that should satisfy that curiosity. If you are a seasonal backpacking guide or regular distance hiker, you will find value in watches that ultimately cost significantly more, but include a handful of features that are helpful (and sometimes essential) for those activities. Higher end models like the Suunto Core have barometric pressure readings, records, and graphs, as well as a compass. The Suunto Ambit3 Peak also has GPS functionality for those who prefer to spend time off of marked trails. On the other hand, if you are training for a huge event (e.g. a marathon, ultra, or long trail thru-hike), then fitness-tracking feature-packed models could be well worth the (considerable) investment. These watches, like the Suunto 9 Baro or Garmin Fenix 5x Plus Sapphire provide health metric insights that go well beyond an 'altimeter watch'.

At this point in our hike  the actual altitude is 11 740 feet. The Suunto Ambit3 Peak (right) is the closet while the Casio SGW300HB is the furthest off.

Altimeter Accuracy


When we looked at altimeter accuracy we considered a few things. First, we reviewed the altimeter interval that each watch uses (which is technically a matter of precision). Second, we looked at the accuracy of the altimeter reading after we calibrated it and hiked to a known altitude. We would then hike back to the trailhead to see if the elevation change showed zero, or if the reading was off by a few (hundred) feet. We also considered the frequency of necessary calibration and the range and frequency of a model's inaccuracy (i.e. did it get it right all or most of the time? If it was off, by how much?). Lastly, we looked at how well the watch was able to keep a stable altimeter reading while sitting in the same place for a few days (even with weather changes).


Of the all the watches tested, the Suunto models Ambit3 Peak, Core Alu and 9 Baro scored the highest in altimeter accuracy. The Ambit3 Peak required fewer calibrations and proved to have an accurate gain and loss profile. This watch, along with the Suunto Traverse and Suunto 9 Baro have the option to use a FusedAlti function that uses both GPS and barometric readings to determine altimeter accuracy.

One thing that every user needs to understand is that all altimeter watches use barometric pressure readings. These readings are subject to change with latitude, altitude, and changes in weather patterns. While some provide a more stable reading than others, none of the watches produced accurate elevation readings without daily calibrations (sometimes two to three times a day).

Checking the altimeter with the actual altitude. San Antonio pass in the Cordillera Huayhuash has a recorded altitude of 16 371 feet.
Checking the altimeter with the actual altitude. San Antonio pass in the Cordillera Huayhuash has a recorded altitude of 16,371 feet.

The Casio PRW-6000Y also provides accurate readings, but a larger altitude interval. Many of the watches display altitude intervals of three feet, as opposed to the Casio's five. The Casio SGW300HB is surprisingly accurate for its no-frills design. However, it scored the lowest in this category because the altimeter interval is 5m/20ft which provides a less precise reading than the rest. Watches could be off on altimeter readings by as much as 500 feet based on the day of testing and we were surprised to discover that a watch with GPS does not always lead to more accurate measurements. In heavy tree cover, a limited signal diminishes the reliability of readings.

A comparison of both altitude  and battery life. Both watches started fully charged. The Traverse shows almost 50 percent less battery life than the Suunto Ambit3 Peak on this hike.

Battery Life


Battery life is of the utmost importance when heading out on any multi-day mission. Since lots of mountaineers, guides, backpackers, and even hikers require a watch that lasts more than just a day, battery life is rated highly in this review. In a lot of ways, the more battery life a watch has, the more reliable it is.

We tested the battery life of all watches. For the GPS watches, we set the watch to low power mode to see how long each could hold out with the GPS function running. We also looked at the type of battery and whether or not the watch is self-charging. GPS watches did not do well in this metric, while regular watch batteries proved to be much more reliable.


The watches scoring this highest in this metric are Casio's PAG240B-2 and PRW-6000Y. They are both solar-powered devices that take about six minutes per day to charge in full sunlight. This is a great plus for any long-term adventurer that needs a reliable compadre. Unlike the PRW6000Y, the Casio SGW300HB features a simple watch battery (not a built-in solar panel) that is rated to last three years. The Suunto Core Alu also has a regular watch battery but is only rated to last 12 months. All other GPS models feature a rechargeable lithium-ion battery that you plug in to charge.

The Suunto Ambit3 Peak made it about 22 hours with the GPS mode on with power save options engaged. Without the GPS, this watch lasts roughly one month in regular watch mode. The Garmin Fenix 5x Plus Sapphire does decently for a GPS watch. It managed about 30 hours of GPS time and over three weeks without it. The Suunto 9 Baro is below average and the Suunto Traverse has poor battery life. In GPS mode, it only lasted eight hours. It's fine for day hikes, but not multi-day missions. Without the GPS, it lasts roughly two weeks before needing a recharge.

Ease of Use and Interface


The ease of use metric measures how intuitive it is to use each altimeter watch. We measured how long it took to calibrate the altitude and set the basic time function the first time for each watch. We also considered how easy it is to use the watch without consulting the user manual. We also looked at the button size and how functional each was with a set of gloves to mimic cold weather conditions.


After our testing, we learned that the Casio SGW300HB is the easiest to use, while the Garmin Fenix 5x Plus Sapphire is the easiest to set up. The Suunto brand watches were a close second. We love the simplicity of the touch screen of the Suunto 9 Baro.

The complex Casio PRW-6000Y is by far the hardest to figure out. We also thought the GPS-based watches (Garmin Fenix 5x Plus Sapphire, Suunto 9 Baro, Suunto Traverse, and Suunto Ambit3 Peak) in addition to the Suunto Core Alu, are the easiest to use with gloves. The Casio models are difficult to use with thick gloves as the buttons are recessed a bit more.

Features


Every altimeter watch has a few basic functions. These include an altimeter, barometer, and a timekeeper. Most also come with a compass. There are many watches out there, and with the onset of more GPS watches entering the market, there are a plethora of features that are being packed into these tiny devices. In this metric, we looked at the features of each watch.


To determine which watch scored the highest, we tallied up the features of each model. We also looked at the quality of the features, whether or not graphs were generated for specific functions (like altitude and barometric pressure), and how helpful the data was on the trail. In the end, we learned that the Garmin Fenix 5x Plus Sapphire was undoubtedly the best in this category featuring all the basic altimeter functions and a slew of others. The Suunto 9 Baro is close behind, followed by the Ambit3 Peak. The most basic Casio SGW300HB scored the lowest in this category.

Altimeter


Of all the watches tested, we really liked the GPS watches' features when it came to altimeter readings. In general, we looked at the type of altitude profiles generated (i.e. ascent and descent over time) and the number of logs each watch could store.

Altitude Profiles: The quality of the graphs produced from each watch varies considerably based on the manufacturer and price point. We really like the clarity of the Garmin Fenix 5x Plus Sapphire as well as its use of different colors for different readings. The Suunto Ambit3 Peak and Suunto Traverse produce the same kind of graph that was also good. The Core also produced a graph but we found it small and harder to read in comparison to the others. The output of the Casio PRW-6000Y only shows the most basic information, and it's hard to see and use. The Casio SGW300HB, on the other hand, does not produce any graphs, one of the many reasons it scored lowest in this category.

A look at the data produced with the Ambit3 Peak in the logbook. Surprisingly  there is no summary altitude map like we saw with the Suunto Traverse.

Data Logging: All the GPS watches win out again for the type of data taken and the logs created. All of these models produce data logs that showed an altitude graph, total ascent, total descent, and altitude change. In some cases, they had even fancier features to better analyze the data collected.

GPS watches again tend to win out because once the logs are synced with a phone or computer app, you can clear the log cache in the watch, which means you can take as many data points as you want. That said, the Suunto Core can hold up to 16 logs, while the Casio PRW-6000Y can hold up to 30. The Casio SGW300HB does not hold any logs.

Barometer: All the watches we tested feature a barometer and capture barometric trends in some way shape or form. For this feature, we looked at the quality of the barometric graph and whether or not the watch allows you to manually change the sea level pressure. We did this by taking the watches to the same location, calibrating them to the same barometric pressure, and looking at the graphs produced as a result.

Overall, we learned the Garmin Fenix 5x Plus Sapphire shines for its barometric trend graph. It allows a plot timeframe of either 6, 12, 24, or 48-hours, which allows the most effective pressure trend capture of all the watches tested. The Suunto Ambit3 Peak and Suunto Traverse feature a similar graph, but it can't be adjusted for different time intervals. The outputs also do not look as nice. The Suunto Core has a decent graph that shows a trend over a seven-day period.

The digital compass provides a directional reading in degrees.

Compass


All the watches tested in this review (with the exception of the Casio SGW300HB) feature some kind of compass function. Most of the compasses in this review have tilt-compensation technology (meaning you don't have to keep your wrist horizontal to get an accurate watch reading) except for the Casio models. A little archaic in comparison, you have to keep your wrist level and horizontal to get an accurate reading.

However, if you're into old-school devices, these models might be right up your alley. In general, we find the compasses useful to get a general point of reference, but on the whole are not nearly as reliable as a regular compass. If you're planning a bush-whacking bonanza, make sure to bring the old map and compass — don't just rely on your watch.

In addition to the compass function, many of the GPS watches can actually navigate to and from different points. You can also mark waypoints and navigate back to them, should you get lost or forget your route. Learn more about these in the GPS section!

Time Keeper and Alarm


They are watches, after all, so all of the models that we tested feature some sort of digital timekeeper in addition to a stopwatch, countdown timer, and alarm. The Casio brand watches like the Casio SGW300HB and the Casio PRW-6000Y stood out for having five alarms as opposed to just one. In addition, both watches feature a world clock with different time zones. The SGW300HB showcases 31 time zones while the PRW-6000Y has 29.

In general, we like the GPS watches better for time simply because the GPS automatically changes the time when entering a different zone. The Suunto Core, Suunto 9 Baro and Garmin Fenix 5x Plus Sapphire have (at least) a dual time option that allows you to enter the current time of your current location in one place, and keep your home time in another. All watches except the Casio PRW-6000Y have a long alarm duration and volume. We would have liked to see a longer beeping time with the Casio as it wasn't long enough to wake us up during some deep sleeps.

In our testing  we went canyon hiking and wore each GPS watch. In this test (among others) we were able to determine which GPS proved to be a little more accurate than the rest.
In our testing, we went canyon hiking and wore each GPS watch. In this test (among others) we were able to determine which GPS proved to be a little more accurate than the rest.

GPS


To test GPS, we ran three different routes with varying GPS accuracy. The first was an open road, the second, a tree-covered trail, and the last was a canyon. We did these tests numerous times, in a variety of weather conditions, to see which truly performed the best. In the end, we learned that none of the GPS watches were 100 percent accurate all of the time, but some watches were a little more reliable with their readings than others. In this case, the Suunto Ambit3 Peak Peak proved to have the best GPS accuracy — most of the time.

Some days, one watch will be more accurate than another, even with similar weather conditions. The Garmin Fenix 5x Plus Sapphire was spot on much of the time but occasionally would have an off day. Of all of the watches tested, the Suunto models proved to be the most accurate most often, except for the Suunto 9 Baro, which was sometimes tragically incorrect. The Suunto Traverse proved to be a little less accurate than the Ambit3 Peak. If you're looking for the watch with the most reliable GPS readings, the Suunto Ambit3 Peak or the Garmin Fenix 5x Plus Sapphire are your best bets.

Display Quality


When looking at display quality, we simply evaluated each screen, its size, and how easy it is to see during both the day and night. We also looked to see if the background color settings could be changed, and how easy it was to see the watch in all conditions. In the end, a large watch face with a mineralized glass composition and different colors scored higher than those without.


The Garmin Fenix 5x Plus Sapphire and Suunto 9 Baro earn the top spot for this category; we like their sharp and colorful displays. These watches truly stand out from the rest. The Casio PRW-6000Y also proves to have a crisp, non-reflective display. However, we aren't too happy about the tiny digital window that made some of the data hard to see.

The Suunto Ambit3 Peak also has a great display. The font and colors of the watch face for both GPS Suuntos are the same, but the mineral glass is a little bit different. The Suunto Core also provides a nice, easy-to-read display, but the watch face background is not interchangeable like all the other watches mentioned above, and the font is harder to see in bright sun or low light. In addition, the nighttime light is a little weak in comparison to the rest.

The Casio SGW300HB comes in last with its much smaller and less durable watch face. The old-school font is easy to see, but not as nice as the other options out there.

Comfort and Fit


When evaluating comfort and fit, we looked at which watches felt the most comfortable on the wrist. We gave these watches to a slew of friends and family to get some additional input on both. We looked at the band material, the breathability of the band, its weight, whether or not the watch would fit well over and under clothing, and whether or not the band had an ergonomic fit. In the end, watches with a more ergonomic fit, a more breathable band, and slimmer profile scored higher than those without.


The Suunto Core and Suunto 9 Baro are both great options here. The former has a slim watch face that sits comfortably on the wrist. The latter has a nice flexible band (as does the Garmin Fenix 5x Plus Sapphire) that compensates for its bulkier display.

Shown here is an insert around the watch face that provides a more ergonomic fit. The Ambit3 Peak  Suunto Core Alu  and Casio PRW-6000Y all feature this design. All of our testers agreed these watches were more comfortable than those without the insert.

The Casio PRW-6000Y is the only watch that features a carbon fiber insert in its lightweight construction, making it one of the most durable bands we tested. We also like its ergonomic fit and lighter, thinner profile. The Suunto Traverse also features a lightweight design, but many of our testers did not like the non-breathable band. The band is also attached directly to the watch face, making it less ergonomic than the others.

The Garmin Fenix 5x Plus is big. Even though many of our testers liked the large display for checking stats, we feel that the watch face is large and bulky, and often hard to fit underneath clothing. Its saving grace is the highly flexible, adaptable band. The Casio PAG240B-2 scores lowest; the rigid, thick, scratchy, cloth-like band is not very comfortable to wear. It also proved to be less breathable, and hard to fit over layers.

Whether you're hiking  backpacking  or just going out for a day of fun  an altimeter watch is a great tool to have. Before buying  make sure you're looking at the watch with the best value and one that best suits your needs in the great outdoors.

Conclusion


The watches that we tested in this category feature important functions that hikers, backpackers, and climbers want most. In addition to telling the time, these features include altimeters, barometers, and digital compasses. We tested the performance of each of these attributes all while rating the ease of use and the products' interface to help you narrow down your selection and find the best product to purchase. We know that selecting just one watch from the pack can be difficult, but we hope that this review is a helpful resource.
