COROS APEX 2 vs. APEX 2 Pro: Which Should You Pick?

Both the COROS APEX and APEX Pro got a much-anticipated refresh in November 2022, with more accurate tracking, even longer battery life, and more. But now that the APEX 2 and APEX 2 Pro are sold in the same listing as different versions, it’s harder to choose between them.

In this post, I’ll go over the reasons to choose one over the other. For context, I’m a distance runner who mostly trains for half and full marathons, but I’ve also dabbled in triathlons and trail running. I’m a GPS watch nerd and have tested all the COROS watches and several others, and want to help you make a decision (check out the rest of my GPS watch comparisons).

Reasons to Choose the APEX 2

The APEX 2 is the more basic version of the two watches, so this section is naturally going to be shorter. But, this watch is still packed with features and could be the better choice for you.

For one, it retails at $100 cheaper than the APEX 2 Pro ($349 vs. $449), so if you won’t need its extra features, going with the APEX 2 can save you some money.

Physically, the APEX 2 is also smaller and lighter than the APEX 2 Pro. The APEX 2 screen size is about 43mm in size while the APEX 2 Pro is 46mm. At 42g with the nylon band, the APEX 2 is 26% lighter than the APEX 2 Pro at 53g (with the silicone band, the weights are 53g for the APEX 2 and 66g for the APEX 2 Pro).

Do note that the screen size is slightly smaller at 1.2 inches vs. 1.3 inches.

If you have a small wrist like me, you’ll probably prefer the APEX 2 over the APEX 2 Pro. The band size for the APEX 2 Pro is 2mm wider than that of the APEX 2, and the APEX 2 Pro is heavier, which makes it less comfortable to wear.

In fact, the default nylon band for the APEX 2 Pro would actually be too long if your wrists are smaller than mine, as the extra band length hits just under the watch face for me. For reference, my wrists are around 5.5 inches (14cm) in circumference.

There’s a tiny bit more leeway with the silicone band on the APEX 2 Pro, but it’s not as comfortable to wear since the band is heavier.

If you still want the APEX 2 Pro despite having smaller wrists than me, the support team may be able to help you out, and I’d recommend reaching out to them before your purchase.

If you want a more feminine color option, the APEX 2 comes in a coral/rose gold option (along with silver and black), while the APEX 2 Pro has a forest green option outside of silver and black.

Reasons to Choose the APEX 2 Pro

The APEX 2 Pro is the more premium watch and retails at $449. It looks more rugged and has longer battery life to support you on your outdoor adventures. Here’s a quick comparison chart:

Regular Use17 days30 days
GPS45 hours75 hours
All Systems30 hours45 hours
Dual FrequencyN/A26 hours

In certain modes, you get almost twice the battery life from the APEX 2 Pro than the APEX 2. While playing music in GPS mode, the APEX 2 has 8 hours of battery life while the APEX 2 Pro has 17 hours, and in All Systems On mode, it’s 7 hours and 14 hours, respectively.

While testing the watches, the APEX 2 lasted me 16 days and 6 hours of tracking in All Systems mode. I could’ve gotten a few more days out of it, but I usually charge my watches after they dip under 30%. The APEX 2 Pro, however, lasted me 22 days and almost 12 hours of tracking in All Systems mode, and .75 hours of tracking in Dual Frequency mode.

Speaking of Dual Frequency mode, the APEX Pro is able to get L1 and L5 satellite frequency signals, improving tracking accuracy. This mode may be helpful if you’re training in big cities or remote areas with tree cover or cliffs.

The APEX 2 and APEX 2 Pro track basically the same activities, except the APEX 2 Pro also tracks Multi-Pitch Climb. You can select the Grade System (Rock YDS, Rock French, Rock Aid, Ice, Mixed) and the phase (approach, climb, descend).

While both the APEX 2 and APEX 2 Pro have landscape and topographic maps, the APEX 2 Pro comes with the global landscape maps preloaded. For the APEX 2, you need to download the regions you want separately from the COROS website, which is easy to do, but can take a good couple hours since the files are larger.

The Bottom Line

The APEX 2 and APEX 2 Pro are both very capable watches. It ultimately comes down to whether you want a larger build, even longer battery life, Dual Frequency tracking, or multi-pitch climbing mode.

Since I mainly do road running and have small wrists, I’d personally go for the APEX 2. But if you spend more time on the trails or are an ultrarunner, you might prefer the APEX 2 Pro.
