COROS Enters the Premium Smartwatch Arena with the New Pace 4 Pro

COROS has officially unveiled its latest flagship timepiece, the COROS Pace 4 Pro. Priced at $449, the new watch represents a significant design and hardware evolution from its predecessors, attempting to bridge the gap between the brand’s historically dominant budget-friendly offerings and the high-end fitness tracking market. At first glance, the device might easily be mistaken for a premium-materials iteration of the standard Pace 4, but a closer examination reveals a sophisticated redesign aimed squarely at competing with top-tier athletic watches on the market.

For years, COROS has enjoyed massive success with budget-focused models like the Pace 3 and the recently introduced Pace 4. However, the company has historically faced challenges attracting consumers to its higher-priced devices, which compete directly with market giants like Garmin. With five years passing since the launch of the top-end COROS Vertix 2—and only minor material refreshes released in the interim—the release of the Pace 4 Pro marks a deliberate and aggressive push to capture a larger share of the premium consumer market. By pricing the Pace 4 Pro at $449, COROS has positioned the device just below Garmin’s Forerunner 570, which retails at $549, inviting buyers to weigh software depth against hardware savings.

What’s New: Hardware and Display Upgrades

Because COROS did not release a prior-generation Pace 3 Pro, the Pace 4 Pro functions essentially as a reimagined, premium version of the existing Pace Pro, adopting the "4" nomenclature to align with current marketing strategies while incorporating advanced features introduced in the standard Pace 4.

The most prominent hardware upgrade is the inclusion of COROS’s largest screen to date: a vibrant 1.47-inch AMOLED display, a step up from the 1.3-inch screen found on the Pace Pro. Resolution has also been increased to 466×466 pixels, accompanied by a staggering peak brightness of 3,500 nits, making it exceptionally easy to read in direct sunlight. This upgraded screen is protected by a durable sapphire glass display, housed within a newly minted titanium bezel that replaces the plastic framing of previous iterations, bringing the total weight of the watch to 38 grams.

Functional enhancements are equally notable. The watch introduces a new fourth-generation optical heart rate sensor, an additional action button, an integrated microphone with voice control capabilities, and a full speaker that finally allows users to take phone calls directly from the wrist. Battery performance has also seen improvements, boasting up to 60 hours of maximum GPS battery life under optimal conditions, alongside a new GPS "Auto" mode that dynamically selects the necessary satellite level depending on the environment. Globally pre-installed offline mapping, dual-frequency multiband GNSS, a barometric altimeter, and 32GB of internal storage round out the core physical specifications.

From a software perspective, the Pace 4 Pro does not launch with exclusive, device-specific features. Instead, it integrates directly into COROS’s standard quarterly software update cycle. Recent additions include updates to the Adventure Journal, direct firmware transfers via computer, and cycling climb alerts. The device is available in black and white colorways, featuring options for either silicone or nylon straps and maintaining compatibility with standard 22mm bands.

The Basics: Daily Operation and Tracking

Navigating the COROS Pace 4 Pro relies on a combination of a touchscreen, a digital crown for scrolling through menus, and physical buttons. The left side features a customizable action button that opens a quick-access control panel or switches directly to the map view during an activity. On the right, the digital crown handles menu scrolling and workout initiation, while the lower right button serves as a back and escape option with long-press shortcuts.

Daily tracking features include comprehensive health and sleep metrics. The watch monitors overnight heart rate variability (HRV), resting heart rate, and sleep stages, pulling all data into the companion COROS smartphone app. The app features revamped sleep dashboards providing clear sleep scores and detailed trend analysis. Real-world testing of sleep tracking indicates that sleep-wake times generally align closely with actual schedules, performing comparably to other leading wearables on the market.

Music storage is included via direct MP3 file downloads and Bluetooth headphone pairing. However, the device does not natively support mainstream streaming platforms like Spotify or YouTube Music due to third-party restrictions, though it does offer media control for music playing on a connected smartphone. Voice control functions also utilize the onboard microphone, allowing users to initiate workouts or record voice notes directly on the device, though traditional button presses remain the preferred method for many users.

Battery performance in daily life generally yields between four and six days of usage, factoring in one to two hours of daily GPS workouts. However, real-world testing of GPS workout battery life has revealed discrepancies with official manufacturer claims. While COROS rates the device for up to 30 hours in always-on display mode with maximum GPS, field testing frequently yields closer to 20 hours. COROS has acknowledged that software bugs related to the GPS subsystem and Bluetooth accessory scanning modes—particularly during cycling activities where the device repeatedly searches for missing sensors at stops—are responsible for the discrepancy and has promised firmware updates to resolve the issue.

Sports Usage and Navigation

Athletes purchasing a COROS watch typically do so for performance tracking, and the Pace 4 Pro includes a robust suite of sport profiles. Selecting an activity is handled via the upper right button, after which the watch locks onto GPS signals and searches for paired accessories like power meters or external heart rate straps.

Navigation features stand out as a core strength, leveraging pre-loaded global offline maps and turn-by-turn routing. Users can import routes from platforms like Strava or GPX files, though routes must be manually synced to the watch via the smartphone app. During active navigation, the watch overlays the route onto the map, providing turn notifications approximately 50 meters in advance. While the system does not support offline automatic re-routing, it indicates the correct compass direction back toward the planned course if a user strays off-path.

Post-workout analytics provide detailed summaries, training load insights, and recovery metrics. The COROS training load system calculates cumulative stress based on completed sessions, though the metrics continue to operate on a weekly cycle that resets every Monday, a point of friction for athletes managing multi-day recovery phases following weekend events like marathons.

Heart Rate and GPS Accuracy

Evaluation of the new fourth-generation optical heart rate sensor reveals mixed results across different training modalities. During steady-state runs and basic interval workouts, the sensor performs admirably, closely tracking expected heart rate curves with only minor transition delays. However, during high-intensity indoor cycling intervals featuring rapid wattage spikes, the optical sensor exhibits noticeable lag when catching up to sudden efforts. Outdoor cycling tracking similarly shows occasional offsets during higher-intensity phases, placing COROS’s optical sensor performance firmly in the upper mid-tier category compared to industry competitors, though still trailing behind dedicated chest strap monitors.

GPS accuracy, by contrast, demonstrates robust performance. Across road runs, street loops, and challenging mountain trail runs utilizing high accuracy settings, the Pace 4 Pro tracks closely alongside high-end competitor devices, maintaining stable positioning even under heavy tree cover where lesser sensors tend to drift.

Wrap-Up

The COROS Pace 4 Pro successfully projects a more premium aesthetic, featuring a brilliant, highly visible AMOLED display and a durable titanium bezel that elevates its physical presence. While COROS positions the watch as a competitor to top-tier flagship devices like Garmin’s higher-end models, the software depth and advanced health hardware of those competitors remain unmatched.

Instead, the Pace 4 Pro serves as a direct challenger to mid-range premium alternatives like the Garmin Forerunner 570. By offering features such as offline mapping and titanium construction at a competitive price point, COROS has created a compelling option for athletes willing to trade niche software features for hardware value, though consumer reception to its higher price tier compared to the standard Pace lineup remains to be seen.
