SATISFY and COROS just made the best-looking mountain watch COROS has ever released

A crystallized black titanium bezel, two bands, three exclusive watch faces, and only $41 more than the standard APEX 4

COROS has done its first collaboration with an apparel brand, and it picked well. The SATISFY COROS APEX 4 ($520) takes the mountain sport watch COROS launched last October and runs it through the lens of the Paris-based technical running brand that has spent the last few years quietly becoming one of the most distinctive names in running apparel.

It goes on sale Friday August 21 at 4PM CET, at satisfyrunning.com and coros.com.

The important thing to understand up front is that this is not a spec upgrade. The engineering underneath is the same COROS APEX 4 that already impressed me (read my review below), with the same dual-frequency GPS, the same 65 hours of battery, the same sensor stack.

What has changed is everything you look at and touch.

What SATISFY actually changed

The bezel. An exclusive ice crystallized black titanium bezel, which is the single biggest visual departure from the standard model. Paired with sapphire glass over the 1.3-inch always-on MIP touchscreen.

Two bands in the box. A khaki nylon band woven with the SATISFY wordmark, and a green silicone band for wet conditions and harder efforts. Getting both included at this price point is a genuinely good deal, since COROS bands normally run $30 to $50 each.

Three exclusive watch faces, designed by SATISFY rather than COROS: Physical Overview, Training Overview, and Environment Conditions. These are built specifically for this edition and are not available on the standard APEX 4.

Three exclusive training sessions, built by SATISFY pro athlete Stian Sommerseth and loaded onto the watch.

The campaign was shot in the Pyrenees following SATISFY pro athlete Vaida Nakrosiute and runner Essaw "Essi" Tesfom Tekle across technical alpine terrain, with every meter of the 19.66 km logged on the watch itself.

The price is the surprise

Here is where this gets interesting; the standard COROS APEX 4 46mm retails at $479. The SATISFY edition is $520.

That is a $41 premium for an exclusive titanium bezel finish, a second band worth roughly $40 on its own, three custom watch faces, and three exclusive training sessions.

Collaboration editions in this category routinely carry premiums of $100 or more, and plenty of them deliver less. On pure value terms this is one of the more reasonable special editions I have seen.

Why COROS chose SATISFY

Brice Partouche, SATISFY's founder and creative director, framed the partnership as something that grew out of genuine use rather than a marketing arrangement: he had been running in the APEX for years before the collaboration existed. COROS CEO Lewis Wu was direct about the motivation, saying the brand wants to make the best-looking watches, not just the best-performing ones.

That is a notable shift. COROS has built its reputation on engineering, battery life, and value, and has historically been more function-first than design-led.

It is also the second design-led special edition from COROS this year. Back in May the brand released the PACE 4 Jakob Ingebrigtsen edition, a $289 athlete collaboration built around the Norwegian's Olympic career, with a transparent dial and gold accents.

That one came from a two-year working relationship with an athlete. This one comes from a brand partnership. Different routes, same destination: COROS is putting real effort into how its watches look, not just what they do.

Who this is for

If you already own an APEX 4, there is no functional reason to upgrade. Nothing under the hood is different.

If you are in the market for an APEX 4 and you like the look, this is close to a no-brainer at a $41 premium with a second band included.
