Our Verdict

The Coros Apex is a simple design ideal for those that want the features found in bulkier models but like the idea of a slim, well-fitting watch. Perfect for those with smaller wrists, the design features the standard Coros menus and tools and recently got upgraded to include navigation features and bread-crumb mapping. The battery life is great, as with all Coros watches, and the integrated mobile application is the easiest to use out of all the major brands. If you are looking for a watch that works well in the outdoors but doesn't scream ruggedness, this could be the perfect model for you.

Our Analysis and Test Results

The Coros Apex stands out for its simple design and extended battery life. Most ultra-athletes will agree that when it comes to a design that omits the extras, this one does it best. If you desire a watch with all the essentials and nothing more, this is a great choice. Those with smaller wrists will also love the Apex.

Features


This small watch packs loads of features, the most out of any we tested in this case size. Equipped with various activity profiles and an ABC (Altimeter, Barometer, and Compass), we think this is the perfect adventure watch for those that need all but the latest and greatest. This model implements the toolbox found across all Coros watches. We wish there were a few more highlights offered that are on the Garmin models, such as find my phone and Garmin Pay, but this certainly isn't a dealbreaker.

Navigational features are basic but satisfactory, and we often found the navigation options on the premium models a bit difficult to use anyway. We normally just pull out our phones. We wish there were a few more health metrics on the Apex, such as a sleep score, but we can't complain too much given the price.

The Coros app is pretty simple and easy to use, and our favorite we tested. If you are looking for a companion app with the most amount of features, Garmin Connect may suit you better. The Coros application lacks social networks, but most folks upload to third-party apps if they care about social integration. We prefer the streamlined nature of the Coros app that doesn't try to do too much.

The Apex contains the essential features for using a GPS watch in the outdoors and is more than capable for any adventure. Increasing the price you will receive more health metrics, longer battery life, and some features like contactless payments and advanced navigation features. While these are nice, we think having just the essentials will work well for most people.

Battery Life


The Coros Apex really stands out because of its incredible battery power. There are two size options with different battery life claims. We tested the 42mm, which has a lower amount of battery life than the 46mm option. Overall, it scores well in this metric for the ample amounts of juice it provides.

For the 42mm face, the manufacturer claims 25 days of regular smartwatch use, 25 hours in GPS watch mode, and 80 hours in UltraMax mode. In all our tests, these numbers were confirmed, with the watch still offering the same battery life after almost a year of continued use. For the ultra-athlete, this is one we highly recommend, especially if you're out for long stints at one time.

While other options lasted longer in our GPS tests, none could hold a charge with continued use throughout an entire month. We learned that with 3 - 4 activities per week lasting 1 - 3 hours, we only had to charge the Apex once a month. Every other contender only lasted about 1.5 to 2 weeks. Boy, are we impressed.

During our GPS test, we laid the watch out with GPS running in an area with good reception. The 42mm version ran for 31 hours, capturing full statistics the whole time. During a long run, hike, and bike, we got the GPS from 100% to 0% in closer to 24 hours with all sensors turned on, just an hour less than the manufacturer claims, making it a good option for most ultradistance events.

Charging takes only 70 minutes. While you can charge the Apex during activity and still use the watch, you need to take it off, which means you can't track your heart rate. Overall, we are impressed with battery life, making this a recommendation for ultra or endurance athletes.

Ease of Use


The Apex is very simple to use right out of the box. Set-up takes only a couple of minutes, and, with the help of prompt screens, you're ready to go. The watch features one dial on the right side and a small flatter button. There is no touch screen, limiting options but ultimately making the watch easier to use. Of all options tested, this is one of the easiest to use, earning high scores in our review.

We like the precise controls and fluidity of the scroll wheel, but we had to lock the device to prevent unintending scrolling. This one-second lock is not a dealbreaker but was more annoying than watches with less exposed dedicated buttons.

As we stated previously, the Coros app is the best we tested, and we appreciate the thoughtful design over the headache that is the Garmin Connect app. The design works well, and you aren't bombarded by widget cards and unuseful information. If you want a simple design experience, we suggest choosing a Coros model. If you largely aren't that interested in viewing the data on the app and prefer looking at your stats on third-party sites like Strava, this may not be as important to you.

Fitness files can easily be shared with friends or exported as a .fit, .tcx, .gpx, .kml, or .csv file. We haven't seen this easy export with Suunto or Garmin Apps yet. While it's available on those other platforms, it's harder to find than on the Coros app, where it's just under the share setting. Updates also seem to be occurring all the time.

Accuracy


We tested the accuracy of both the GPS and heart rate monitor, and accuracy was above average for both. We did this while open water swimming, riding bikes, cross-country skiing, backcountry skiing, and trail running in some pretty remote terrain. We'd say that 99.9% of the time, we trusted the data that we got, with this being verified in our tests. This is one of the most accurate watches we've tested, earning it top marks here.

During our three-mile GPS test on a remote road in Colorado where we compared all of the test watches, this one performed as well as the others. We found only +/- 0.01 miles of variance. All the watches we tested feature similar antenna designs and sampling rates, allowing them to easily access many different satellite options. That said, if you plan to travel in steep technical terrain, you may want to look into a dual-frequency model, which is much more precise and removes error by refracting satellite signals.

Accuracy for the heart rate monitor had mixed results. While most wrist heart rate monitors are notoriously inaccurate, we thought that the fit of the Apex with its smaller face would help with this. However, during both our sitting tests and active tests, the variation was large, with the heart rate being off by 2 - 20 bpm. During our runs, we noticed that our heart rate always seemed a little higher than normal. Our main testers resting heart rate is close to 60 bpm, but on the Coros watch, it consistently showed a heart rate about 10 bpm higher. While we want our wrist heart rate monitors to be incredibly accurate, this is dependent on watch fit and a few other factors. If you really want an accurate measurement, be sure to use a dedicated heart rate monitor.

Design


We are big fans of this design and how well it fits many different types of wrists. As features and battery life increase, so does the watch's size, which isn't everyone's design preference. Luckily the Apex comes in two different size options, a 42mm or 46mm face.

There is an auto-lock that requires a full turn before you can access the screen, or you can change this to a long press. If you turn this off, it's very easy to accidentally pause your workout, so we recommend keeping it on. This is one thing that bugs us about the Coros models — when training hard, fully unlocking the watch when the heart rate is high is frustrating.

Our major complaint with this model is the less than bright screen which is often difficult to see under direct light. If you often find yourself running during mid-day, you may want to find a watch that performs better for taking quick glances. The contrast could be better, but ultimately we feel the features and battery life outweigh this negative.

Value


If you are looking for a watch that does all the essentials extremely well at a great price, we highly recommend the Apex. Due to our travel in technical terrain, we appreciate the combination of bread crumb mapping and an on-screen compass. Coros also continues to impress with its battery life and thoughtful app design.

Conclusion


We don't think you'll be let down by the Coros Apex. We love its minimalist design, lower price, and excellent battery life. It particularly stands out for its battery life in Smart mode, requiring just about one to two charges a month, depending on GPS use. Coros is doing a great job in the watch market, and we hope that they continue making smaller models like this one so all people can feel comfortable wearing GPS watches for their activities. If you are looking to start planning more adventures and want the peace of mind of trackback, bread crumb mapping, and a compass, we don't think you can go wrong with the Apex and we highly recommend it.
