Coros Apex 4 vs Coros Pace Pro: Which GPS Sports Watch Makes More Sense?
We put the new Coros Apex 4 through multi-day ultra testing and compared it with the brilliant Pace Pro to see which one deserves a place on your wrist.
Introduction
Coros sent over the new Apex 4 around a month ago, and since then it has been put through a proper testing cycle: battery checks, long runs, and a deep dive into the updated mapping features in some genuinely hostile race conditions, including a multi-day desert ultra. The verdict is mixed in an interesting way. There is a lot to like about the Apex 4, but a familiar rival from Coros’ own lineup, the Pace Pro, still holds a strong claim to being the better all-round choice for many runners.
This comparison breaks down what the Apex 4 does well, where it falls short, and why the Pace Pro remains one of the best GPS sports watches around.
What the Apex 4 Brings
The Apex 4 launched recently and retails in the UK for £429. It is available in two sizes: a 46mm model with an impressive 65 hours of GPS battery, and a smaller 42mm version that still delivers 41 hours with all systems on. The construction is lightweight titanium with reinforced lugs and durable, scratch-resistant sapphire glass. The 46mm model weighs just 63g with the included silicone strap, so it stays compact and comfortable even on longer outings.
The interface will feel instantly familiar to anyone who has used a Coros watch. A quick turn of the toggle wheel opens daily metrics such as running fitness, training load, training status, and recovery time, and you can flick through them on the touch-sensitive screen. Holding the back button opens the main menu with settings, watch faces, music, wellness centre, compass, maps, and more. The usual sport modes are all here: road running, trail, track, hiking, mountain climbing, road and indoor biking, pool swimming, and even more obscure options like pickleball, frisbee, and skateboarding.

The new hardware additions are notable too. The Apex 4 is the first Coros watch with a built-in microphone and speaker, so activity alerts play out loud and clear and you can take hands-free calls on the move. Coros also claims its most accurate vertical GPS algorithm yet, dual-frequency tracking, a precision wrist heart-rate sensor, and a dual-range barometer for sharper elevation and weather data.
Mapping and GPS Accuracy
Coros claims the Apex 4 has its fastest and most powerful mapping system, with free global landscape and topo maps, street and trail names, and turn-by-turn navigation with points of interest. In testing, those claims hold up. GPS accuracy was spot on everywhere it was used, from thick tree cover on local woodland trails to the open isolation of the Moroccan desert.
The mapping was put to a real test during a two-day desert ultra, with day one and day two routes loaded as GPX files. Even though the routes were well marked, mapping and step-by-step navigation ran on both days, and it never skipped a beat. Turn alerts come with a loud alarm and an on-screen arrow, zooming in and out of the map is quick, and the extra detail from street and trail names genuinely helps.

Battery Life and Everyday Wear
Battery life is where Coros has always excelled, and the Apex 4 is no exception. During the desert event, day one covered around 60km in roughly 9 hours and day two about 50km in 8 hours, all with mapping and navigation active. By the finish, the watch still had plenty of charge left. Back home, another full run followed without charging, and the unit still reported 14% battery remaining. That is genuinely impressive endurance for a compact watch.
In terms of size, the Apex 4 is only slightly bigger than the Pace Pro and sits nicely on the wrist. The silicone strap is comfortable, though swapping to the optional nylon band is a popular tweak: it feels even softer, trims a little weight, and offers more adjustment for fit. At 63g in the 46mm version, it is a big step up in wearability compared with older, bulkier Coros models.

Coros App and Usability
One consistent highlight of using a Coros watch is how simple everything is. Setup, pairing with your phone, and daily navigation all feel intuitive, and the companion app is one of the best in the category. It is colorful, bright, and easy to move around, with a huge amount of training data that is actually enjoyable to browse.
Compared with some rival apps from Garmin and Suunto, which can feel lacklustre and awkward to use, the Coros app is a genuine reason in itself to consider this ecosystem. Everything from training load trends to recovery metrics is presented clearly, so the data feels useful rather than buried.
The Display Question
Here is the sticking point. The Apex 4 uses a third-generation MIP display, which Coros chose to protect battery life. It is definitely an improvement on older MIP screens, but it simply does not match the clarity of an AMOLED panel. Reading data mid-run can be genuinely tricky at times, and once you have experienced the super bright, vibrant AMOLED screen on the Pace Pro, going back to MIP feels awkward.
The trade-off is understandable, since AMOLED displays consume more battery. But the Pace Pro’s battery performance is already very good, and for many runners it may not be worth giving up screen quality for extra endurance they will rarely need.
Verdict: Which One Should You Buy?
The Apex 4 is a solid update. Coros took an already good GPS sports watch and made it better, especially with the faster, more detailed mapping system, which is an area the brand needed to address. Turn-by-turn navigation, loud alerts through the new speaker, excellent GPS accuracy, and best-in-class battery all make it a strong choice for ultra runners and anyone who navigates long routes.

But the Pace Pro takes the top spot. Its bright AMOLED display is a genuine highlight, and it packs all the modes and features most runners will ever need into a light, compact unit with great GPS accuracy and strong battery life. It is arguably one of the best GPS sports watches available right now.
If detailed mapping and maximum battery endurance are your priority, the Apex 4 is the pick. If you want the best everyday viewing experience and a brilliant all-round package, the Pace Pro is hard to beat.
Conclusion
Both watches come from the same DNA and share Coros’ easy interface and superb companion app. The Apex 4 pushes mapping and battery to new levels, while the Pace Pro still delivers the more enjoyable screen and a complete feature set in a compact body. Choose based on where you run: remote route-heavy adventures favour the Apex 4, while everyday training and racing favour the Pace Pro.
