Quick answer: The COROS PACE 4 Pro, released September 22, 2026, is a $449 multisport watch built around the brand's biggest and brightest screen yet: a 1.47-inch AMOLED display hitting 3,500 nits inside a titanium bezel and sapphire glass lens. It weighs just 43 grams with a nylon band, runs up to 60 hours of GPS tracking in high-accuracy mode, and doubles the onboard RAM of the standard PACE 4 for faster map rendering. We spent time on the wrist with it and found a watch that punches well above its running-watch label, with one real annoyance in the strap design.

COROS built its name on stripped-down, battery-efficient running watches, and the PACE line has always been the brand's entry point for people who wanted COROS accuracy without COROS Vertix pricing. The standard PACE 4 leaned into that formula. The PACE 4 Pro, which COROS launched today, September 22, 2026, takes the same bones and adds the hardware that used to be reserved for the brand's flagship watches: a titanium bezel, sapphire glass, and COROS's largest, brightest display to date.
At $449, it undercuts comparable AMOLED training watches from Garmin by a wide margin, and after a stretch of runs, hikes, and gym sessions with it strapped on, it's easy to see why COROS is positioning this as more than a running watch.
What's new on the COROS PACE 4 Pro?
The headline upgrade is the screen. COROS gave the PACE 4 Pro a 1.47-inch AMOLED display at 466 x 466 resolution, 22.5% larger than the standard PACE 4's panel, with a max brightness of 3,500 nits. That's brighter than the screen on COROS's own Apex 4 and well ahead of rival watches like the Suunto Run 2, which tops out around 2,000 nits. In direct sun, the difference is obvious. Numbers stay legible without cupping a hand over the face.
That screen sits under sapphire glass instead of the mineral glass on the standard PACE 4, framed by a titanium bezel rather than polymer. It's a meaningful jump in how the watch feels and holds up, and COROS managed it while adding only 11 grams over the base PACE 4. The whole unit is 11.8mm thick and weighs 43 grams with the nylon band, 38 grams for the body alone.
Battery life scales with the bigger screen instead of suffering for it. COROS rates the PACE 4 Pro at 60 hours of GPS tracking in its high-accuracy mode, 45 hours with the always-on display active, and 21 days of general daily use (7 days with always-on enabled). COROS says that's nearly 50% more battery capacity than the standard PACE 4 packed into a watch that's barely heavier.
Quick Tip
How does the PACE 4 Pro perform in daily use?
COROS doubled the onboard RAM compared to the standard PACE 4, and it shows in how the watch handles maps. Panning around a route, toggling between map layers, and pulling up turn-by-turn navigation all feel noticeably snappier than on earlier PACE watches, where map redraws could lag for a beat. With 32GB of onboard storage, there's room for offline maps, music, and a full season of workout history without having to manage space.
The watch also picked up a built-in speaker and microphone, enabling a talk feature when paired with a phone. Asking for a quick weather check mid-run and getting a spoken answer back, instead of stopping to dig through menus on the phone, is a small thing that ends up genuinely useful on days when the sky looks uncertain.
Navigation itself is handled through a touchscreen paired with a physical crown, and that combination turned out to be one of the PACE 4 Pro's better design decisions. The touchscreen is responsive enough for quick swipes, but the crown makes scrolling through longer menus or data screens faster and more precise, especially with sweaty fingers or gloves on. It's a small hybrid approach, but it removes a lot of the fumbling that touchscreen-only sport watches can create mid-workout.
How accurate is the heart rate tracking?
The PACE 4 Pro uses COROS's 4th-generation optical heart rate sensor, a 5-channel PPG array, paired with dual-frequency GPS for positioning. Run after run, the wrist-based heart rate numbers tracked closely with a chest strap monitor running alongside it, close enough that we stopped second-guessing the on-wrist number during interval work, which is usually where optical sensors drift the most under sudden effort spikes.
That consistency matters for the watch's training tools, which include VO2 max estimates, training load, running fitness scores, and pace strategy guidance built from real effort data rather than a rough average. The watch also tracks overnight HRV, sleep stages, sleep consistency, and daily stress, alongside COROS's now-standard nutrition, heart rate, off-course, storm, safety, and altitude alerts.
Who is the COROS PACE 4 Pro built for?
COROS still frames this as a running watch first, and the battery life, GPS accuracy, and pace-focused training tools back that up. But the feature set reaches well past road and trail running. Cyclists get dual-frequency GPS and route building. Hikers and adventure travelers get storm and altitude alerts plus a genuinely large, bright map display. Gym-goers get workout and training-plan support without needing a second device. It's a watch built for one primary sport that happens to carry enough depth to cover the others without feeling bolted on.
It's a light running watch on the surface, but there's a lot more under the hood for adventure seekers, fitness buffs, and cyclists alike.
What's the one drawback?
The band. COROS uses a push-button quick-release strap system on the PACE 4 Pro, and in practice it doesn't hold the strap as securely as a standard pin-and-loop design. Getting the strap seated into the right hole took more fiddling than it should have, and there were a few moments where it felt less locked-in than expected. It's a minor gripe against everything the watch gets right, but after enough runs with it, it was the one thing that kept coming up. A simpler strap loop system would remove the issue entirely.
How much does the COROS PACE 4 Pro cost, and where can I buy it?
The COROS PACE 4 Pro is $449 and available now in black and white colorways at coros.com/pace4pro. That's a step up from the standard PACE 4, which starts at $249 for the polymer version and $279 for aluminum, but it lands well under comparable AMOLED training watches from other brands, including Garmin's Forerunner 570 ($549) and Forerunner 970 ($749.99).
The bottom line
The COROS PACE 4 Pro takes the affordable, battery-efficient formula that made the standard PACE 4 popular and adds the hardware upgrades that used to separate budget watches from flagship ones: a titanium bezel, sapphire glass, and the brightest screen COROS has built. It's light enough to forget you're wearing it, tough enough to take a few knocks, and capable enough to cover training well beyond running. The strap system needs work, but it's a small complaint against a watch that otherwise delivers far more than its price suggests.
