Coros Pace 4 Pro Review: A Big-Screen AMOLED Running Watch That Gets the Fundamentals Right

Introduction

Coros has been quietly building a reputation for sports watches that punch well above their price, and the Pace 4 Pro is the clearest expression of that strategy yet. Sitting above the standard Pace 4 in the range, it replaces the older Pace Pro and shifts the emphasis firmly toward design: a bigger, brighter screen, tougher materials and a more premium finish, while keeping the thin, lightweight character the Pace line is known for.

After nearly two weeks of daily running, three races and side-by-side testing against some of the biggest names in the category, the short version is this: the Pace 4 Pro is arguably Coros’s best watch to date and one of the strongest value propositions in running watches right now.

Design: Big Screen, Small Body

The design is really the only reason to choose the Pro over the standard Pace 4, and it is a compelling reason. You get a 47mm case that is only around 12mm thick, so despite the larger footprint it still sits comfortably on slimmer wrists and nearly disappears during all-day wear. That is a rare trick for a watch with this much screen.

The AMOLED display is the standout. It reaches 3,500 nits, making it the biggest and brightest screen Coros has shipped, and it stays legible at an angle even in the low-power race-to-wake mode. Sapphire crystal protects the front, something no previous Pace watch offered, and a titanium bezel replaces the plastic or aluminium of the cheaper Pace 4. The look is sporty but restrained, more paired-back than the adventure-watch aesthetic of the Garmin Fenix range.

Controls follow the familiar Coros formula: a three-button layout with a digital dial for menu navigation and an action button on the left for switching between screens during activities. Navigation feels quick and responsive, whether you are panning maps with the touchscreen or working the buttons. The only obvious omission from the hardware is a built-in flashlight, which some rival watches include at the cost of extra thickness.

Spec highlights include 22mm strap compatibility, a 5 ATM waterproof rating, multi-band GPS, Coros’s latest heart rate sensor, barometer, altimeter and compass, plus a mic and speaker for voice commands. Storage is 32 GB for music and maps.

Accuracy: GPS and Heart Rate

GPS performance has been excellent. On a twisting, turny half marathon course in central London, the Pace 4 Pro matched top-tier multi-band Garmin watches almost exactly for distance, pacing and post-run track quality. Testing across mixed terrain, open heathland, roads and tree cover, left nothing to choose between the Pace 4 Pro and a Fenix 9 Pro on out-and-back routes. Even in genuinely tricky conditions for satellite reception, there were no complaints.

Heart rate accuracy is very good, though slightly less flawless. On runs and indoor rides the optical sensor closely tracked a chest strap, occasionally lagging a touch behind. It can be a little fussy settling in during the opening minutes of a workout, and it sometimes reads slightly high with the occasional spike, particularly during strength workouts where optical sensors typically struggle. For key sessions, a chest strap remains the last word in accuracy, but the onboard sensor covers the vast majority of runs well.

Training Analysis and Features

The training tools will be familiar from recent Coros watches: lactate threshold, VO2 max, race predictions and training load. In testing, these numbers rang true and the presentation is clear and easy to access on the watch. It is not as deep or extensive as what Garmin offers, but it delivers the core data in an engaging, digestible way.

Newer touches are welcome. Sleep consistency tracking has been added, which many consider the most important sleep metric. There are also new heart rate tools that split trends across the day, sleep and exercise in a single app tab, making it easier to spot anomalies and shifts over time. A voice notes feature records quick post-run feedback and automatically transcribes it in the app, which works nicely as a lightweight training diary. Live tracking can now be scheduled and shared in advance.

Battery Life and Charging

Battery life is where Coros traditionally excels, and the Pace 4 Pro continues that. The official figures are 21 days in race-to-wake mode, 7 days with the always-on display, and 30 hours of GPS tracking with the screen always on in the most accurate multi-band mode.

Real-world testing beat the estimates. With the always-on screen at full brightness, real-time heart rate monitoring outside workouts and GPS set to maximum accuracy, the watch still lasted more than 7 days while running every day. On a roughly 6-hour run, it burned just 14%, with frugal 7% burns on 3-hour and 2h45 runs, about as efficient as any watch tested in these conditions, and just behind a Fenix 9 Pro. Overnight drain was a minimal 1 to 2%.

Charging uses an adapter that connects to any USB-C cable, and rapid charging is genuinely useful: 30 minutes plugged in buys you around 10 hours of run time. That is enough to rescue most long runs from a forgetful charge.

Mapping, Navigation and Everyday Features

Offline maps are on board and work well. Routes are easy to load through Coros’s app, the map builder is capable, and panning around maps is fast and smooth. Following routes during runs proved easy to read on that large, bright display.

Music support is more limited: you can drag and drop MP3 files to the 32 GB of storage, but streaming services are not supported. Smart features generally trail Garmin too, with no NFC contactless payments and a narrower set of watchface-style extras. Coros has been adding useful things though, including the mic and speaker, voice commands, and camera controls for compatible action cameras.

Things to Consider Before Buying

If the big-screen design does not appeal, the standard Pace 4 remains the better value pick, since the software features are largely the same. The Pace 4 Pro also lacks the deepest training analysis, a built-in flashlight, streaming music and NFC payments that flagship Garmin watches offer. On the flip side, it is slimmer and lighter, lasts longer on a charge, and costs less than the Forerunner 970, as well as undercutting a discounted Forerunner 965.

Buying Advice

At £399 or $449, the Pace 4 Pro lands at a price that undercuts last-generation flagship Garmin watches even on sale, while delivering multi-band GPS accuracy that matches them, battery life that beats most AMOLED rivals, and a design many will prefer to watches costing considerably more. For runners who want 95% of the tools they will ever need in the most wearable package, this is one of the best value running watches on the shelves right now.

If you want the absolute ceiling of smart features and training depth, Garmin still has it. But if you want the best combination of screen, comfort, accuracy and battery life for the money, the Pace 4 Pro makes a very strong case.

Conclusion

The Coros Pace 4 Pro is a confident step forward: a genuinely thin, light 47mm watch with the biggest, brightest display Coros has made, protected by sapphire glass and framed in titanium. Accuracy matched the best in class, battery life exceeded expectations, and the software covers the core running, training and recovery needs with a few thoughtful new additions. It may not match a flagship Garmin feature for feature, but on the things runners actually use daily, it competes at the top while costing meaningfully less. That is a combination that is hard to argue with.
