The £389 Pace 4 Pro brings AMOLED, sapphire glass, titanium and advanced training tools to COROS’s most premium sports watch yet, although GPS battery life and heart-rate accuracy still have caveats.
COROS has spent years winning praise for affordable performance watches, but the Pace 4 Pro is a more deliberate push into the premium segment. At $449, or £389 in the UK, it sits well above the standard Pace 4 and is designed to tempt runners and triathletes who want more polished hardware without crossing into Garmin’s highest prices. According to DC Rainmaker’s review, that strategy is partly about appearance as much as specification: the watch looks and feels distinctly more upmarket, yet it is still meant to undercut the better-known premium rivals that dominate this part of the market.
The hardware changes are substantial. The Pace 4 Pro uses a 1.47-inch AMOLED panel with 466 x 466 resolution, sapphire crystal, a titanium bezel and COROS’s brightest display to date at a claimed 3,500 nits. It also adds a microphone, speaker, voice control, call handling from the wrist, an action button and the company’s newer optical heart-rate sensor. Tom’s Guide described it as slim and light despite the premium materials, while iRunFar noted that the larger screen and longer battery life help make it feel more like a fully formed flagship than a simple Pace variant.
Battery life remains one of the watch’s most important selling points, although the headline figures need context. COROS claims up to 21 days in regular use and up to 60 hours of GPS tracking, depending on mode, while the review by DC Rainmaker found day-to-day endurance closer to four to six days with heavy training use and less convincing results during workouts than in the company’s own charts. The same review says COROS has acknowledged a battery-drain issue in GPS modes and expects an update in November to address it. That means the practical endurance story is still strong, but not quite as simple as the marketing suggests.
In sports use, the Pace 4 Pro keeps COROS’s familiar formula intact: offline maps, turn-by-turn navigation, dual-frequency GPS, structured workouts, training load, recovery data and HRV tracking all remain central. The watch can also handle route imports, voice notes and post-workout journalling, while the company continues to push regular firmware and app updates rather than treating the product as finished at launch. Reviewers across Tom’s Guide, iRunFar and Active.com all pointed to the same conclusion: the core athletic features are strong, the interface is quick, and the watch is clearly aimed at serious endurance users who care more about training tools than smartwatch extras.
Accuracy is where the Pace 4 Pro looks competitive, if not class-leading. Tom’s Guide said GPS and heart-rate tracking were accurate enough to stand alongside far more expensive rivals, while DC Rainmaker found the new sensor improved over earlier COROS hardware but still short of the very best in the market, particularly in harder cycling intervals and rapid intensity changes. That leaves the Pace 4 Pro in an interesting position: good enough for demanding training, more luxurious than previous Pace models, and priced aggressively against Garmin’s Forerunner line, yet still not the obvious choice for buyers who want the richest smartwatch ecosystem. For endurance athletes who value maps, battery life and training tools over app stores and payments, it looks like COROS’s most convincing premium watch so far.
