Coros Apex 4: First Leaks Confirm Another New Coros Watch Is Imminent
More: Coros Apex 4 Review
The Coros community seems set to explode with excitement as the first leaks of the Coros Apex 4 (four!) have surfaced. Coros is lining up for another game-changing release in two case sizes.
Several things can be inferred from the images and prior releases. Added to that is an official announcement teasing the launch by Coros of ‘something’ on October 15th….oh, and about 10 photos of the darned thing shown here 🙂 Let’s explore.
Premium Design | High-End Materials
The initially leaked images were a render, showing a sleek, circular watch that builds on the aesthetic of the Coros Nomad and Pace Pro. On the reverse, the render declares its specs: titanium case, Sapphire screen, Barometer, 5 ATM water resistance, and Dual-Frequency GNSS.
These are definitely high-end specs. Titanium and Sapphire are reserved for most brands’ top-level products, and Coros will be no exception. The barometer and water resistance add little new, and dual-frequency GNSS is also nothing new for Coros—all those additional aspects of the product would be routinely expected for a new Apex.
Digging deeper and getting a ruler out, we can infer a 45/46mm case diameter and 22mm band width, likely the Coros copy of QuickFit. But since then, we have confirmed two case sizes—42mm and 46mm.

For comparison, here are the case sizes of existing Coros watch models. (Apex 4 confirmed with 42mm and 46mm options)
| Model | Case Size |
|---|---|
| PACE 3 | 42 x 42 x 11.7 mm |
| PACE Pro | 42 x 42 x 11.8 mm |
| APEX 2 | 43 x 42.8 x 12.8 mm |
| APEX 2 Pro | 46.1 x 46.5 x 14 mm |
| VERTIX 2 | 50.3 x 50.3 x 15.7 mm |
| VERTIX 2S | 50.3 x 50.3 x 15.7 mm |
| NOMAD | 46 x 46 x 14.4 mm |
At the top of the watch render, there also appears to be a rectangular area 6 or 7mm wide, possibly a flashlight LED, but that does NOT appear to be the case from the actual photos, so maybe it is the internals for the barometer. Odd.
Then there are the more obvious two-button and digital crown details. The only thing to note here is that in some recent watches, COROS has moved the crown from the 3 o’clock position to avoid accidental presses—fair enough. Keep that.

Coros Apex 4 First Features Leak
There’s a dual-range barometer, and the battery life of each case size has been confirmed. This article also details a few other details, like voice notes that can be tagged to a POI/GPS point.

What else could be New?
The Apex 4 would not be a direct competitor to Garmin Fenix; that’s more the domain of Vertix. Yet Coros is still referring to Apex 4 as a ‘Mountain Watch’…make of that what you will.
Coros will be looking to differentiate its products from Garmin at similar levels, and one of Coros’s strong historical points is battery life. I have a sneaky suspicion that the next Vertix and this Apex will also remain on MIP displays (albeit a later generation of the tech).
When I last spoke to the brand, they were generally reticent about going down the AMOLED route. Pace Pro clearly shows they changed their mind for some watch models; however, their R&D might be slightly behind the curve, explaining slow uptake across the board.

Why Apex 4? Mystery of the Missing “Apex 3”
Strangely, version #3 of the product appears to have been skipped. Even stranger as 4 is an unlucky Chinese number – remember there was no Garmin Fenix 4. Coros is a Chinese company through and through, so… errr…I don’t know.
Stay Tuned for October 15th
As the real product is out in the wilds in China, more product details will likely be made available soon.

Bonjour,
Je croyais que Coros était une marque américaine ?
Salut, tu as toutes les infos ici, à la fois pour l’origine de la marque et pour la sécurité des données.
https://www.nakan.ch/wp/2025/02/27/quelle-marque-de-montres-cardio-gps-fait-le-plus-attention-a-vos-donnees/
Lewus Wu the CEO (went to Zhejiang University) has said that it’s majority owner is chinese (YF Tech), the parent company is Dongguan Yuanfeng Technology Co., Ltd, its manufacturing is in china (Guangdong), but it has offices in many countries in a HQ in Irvine, CA.
Nice design, but the MIP screen feels boring to me after getting used to AMOLED. Coros’s choice of sticking with MIP is really interesting.
the newer MIP technologies get progressively better and more visually impressive
Really?
To me it seems thats half decade that we’re still stuck to the usual 1.2/1.3″ circa 260×260 64colours mip displays… .
I would love an imaginary 1.5″ 420×420 256 colours variable refresh mip display tough…
Thank God there’s still a company that feels AMOLED isn’t really needed in an outdoor watch, just like it’s not needed in an e-book reader. Might after all switch from Garmin who frustratingly went all in on Christmas Tree style screens.
This is where I am too now. AMOLED has enough battery life for me to finish a 100-mile race and go camping for 5 days. For my needs, the battery problem is basically solved and the screen/responsiveness is so much better.
Apex 2 also has a sapphire screen
No small version?
doesn’t appear to be (see below)
Yes, there is a small version. It’ll come in 42mm and 46mm sizes.
