COROS, a prominent player in the competitive landscape of high-performance sports watches, has officially unveiled its latest offering, the COROS Pace 4 Pro. This new model emerges nearly a year after the successful debut of the Pace 4, building upon its predecessor’s foundation with significant upgrades designed to appeal to a broad spectrum of endurance athletes. While Garmin has long been recognized as a benchmark in the training smartwatch segment, COROS continues to solidify its position as a formidable competitor, consistently pushing the boundaries of innovation and user experience. The Pace 4 Pro represents a strategic enhancement, focusing on key areas that directly impact athlete performance and device longevity.
A New Standard in Display Technology for Athletes
The most striking enhancement in the COROS Pace 4 Pro is its substantially larger display. Measuring 1.47 inches diagonally, the new screen represents a 22% increase in size compared to the Pace 4. This makes it the largest display COROS has ever incorporated into one of its smartwatches, a decision that directly addresses user feedback and the growing demand for more expansive and easily readable interfaces during intense physical activity. The increased screen real estate allows for more data to be displayed simultaneously, reducing the need for athletes to scroll through menus mid-workout and providing a more immediate and comprehensive overview of their performance metrics.
Beyond its enlarged dimensions, the display technology itself has seen a significant upgrade. The Pace 4 Pro features an LTPO AMOLED panel, a choice that signifies a commitment to both visual clarity and power efficiency. LTPO (Low-Temperature Polycrystalline Oxide) technology allows for variable refresh rates, enabling the screen to dynamically adjust its refresh rate based on the displayed content. This means that when static information is being shown, the refresh rate can drop significantly, conserving battery life. Conversely, during active use or when displaying dynamic data, the refresh rate can increase for a smoother and more responsive visual experience. The resolution has also been boosted to 466 x 466 pixels, contributing to sharper text and more detailed graphics.
Complementing the advanced display technology, COROS has also enhanced the physical resilience of the screen. The company has transitioned from mineral glass on the Pace 4 to sapphire glass on the Pro model. Sapphire glass is renowned for its exceptional scratch resistance, a critical feature for athletes who often expose their devices to rugged environments, accidental impacts, and abrasive surfaces. Furthermore, the bezel surrounding the display has been upgraded from a fiber-reinforced polymer to a more robust TC4 titanium alloy. This material choice not only contributes to the watch’s premium feel but also offers superior durability and corrosion resistance, ensuring the device can withstand the rigors of extreme training and competitive events. The brightness of the LTPO AMOLED panel has also been significantly improved, reaching up to 3,500 nits. This remarkable brightness level ensures excellent visibility even under direct, harsh sunlight, a common challenge for outdoor athletes.
Extended Battery Life and Enhanced Performance
In addition to the visual upgrades, the COROS Pace 4 Pro delivers notable improvements in battery life and internal performance. COROS claims that the Pace 4 Pro offers up to 21 days of battery life in standard smartwatch mode, an increase from the Pace 4’s 19 days. This extended duration is particularly impressive when considering the larger, brighter, and higher-resolution display. For users who prefer to keep their watch face always on, the Always-On Display (AOD) mode on the Pace 4 Pro now provides up to seven days of battery life, a one-day improvement over the Pace 4. This enhancement in battery efficiency is likely a result of the LTPO display technology and optimized power management software.
Performance has also received a boost with the inclusion of double the RAM compared to the Pace 4. While specific RAM figures are not always disclosed by manufacturers, this doubling suggests a more fluid and responsive user interface. Athletes can expect quicker app loading times, smoother navigation through menus and workout data, and a generally more seamless interaction with the watch’s various features. This performance enhancement is crucial for a device designed for rapid access to critical information during demanding activities.
Design Considerations and Advanced Sensor Suite
The increased display size and robust materials naturally lead to a slightly larger and heavier device. The COROS Pace 4 Pro measures 47.6 x 47.6 x 11.8mm, making it a more substantial presence on the wrist compared to its predecessor. It also weighs 11 grams more than the Pace 4, tipping the scales at 51g with the standard silicone band. However, COROS offers a nylon band option that reduces the weight to 43g, providing a lighter alternative for those who prioritize minimal wrist feel. This design choice reflects a balance between enhanced functionality and user preference for comfort and aesthetics.

The Pace 4 Pro is equipped with a comprehensive suite of onboard sensors designed to capture a wide array of physiological and environmental data. These include advanced heart rate monitoring, an altimeter for precise elevation tracking, an ambient temperature sensor, a pulse oximeter (SpO2) for blood oxygen saturation measurement, and an electrocardiogram (ECG) sensor. The inclusion of an ECG sensor allows users to take on-demand electrocardiograms, providing valuable insights into their heart rhythm and potentially detecting irregularities.
A unique and particularly useful feature introduced with the Pace 4 Pro is the support for voice notes. Athletes can now record voice memos directly on the watch, which are then automatically synced with their workout files. This functionality is invaluable for capturing immediate thoughts, observations, or feedback during or immediately after a training session, eliminating the need to stop and manually log notes. This feature enhances the post-workout analysis process, allowing for richer and more contextualized data interpretation.
Furthermore, users of the COROS Pace 4 Pro gain access to the entire COROS training ecosystem. This integrated platform provides a wealth of training plans, performance analytics, and community features, empowering athletes with the tools they need to optimize their training, track progress, and connect with fellow athletes. The COROS app offers detailed post-workout analysis, long-term trend tracking, and personalized training recommendations based on individual performance data.
