In 2024, the brand Coros made waves with its Pace Pro watch, a device aimed at road runners but featuring advanced tools such as an electrocardiogram and local mapping. Following this success, Coros introduced the Coros Pace 4, which integrated some of the Pace Pro's innovations. Soon after, the brand released a "Pro" version of the Pace 4, focusing on hardware improvements to create a stylish, high-performance watch without a steep price increase. The Coros Pace 4 Pro has dimensions of 47.6 mm x 47.6 mm x 11.8 mm, a 466 x 466 pixels AMOLED screen, 32 GB of internal memory, and weighs 38 grams. It includes an accelerometer, electronic compass, sleep analysis, and ambient light sensor, and is water-resistant up to 5ATM. The Coros Pace 4 Pro is part of Coros's Pace series, known for their slim and lightweight design, ideal for road running. While the Pace 4 Pro is heavier than other models, this is due to its larger size. Compared to competitors, it still feels notably light. The watch features three buttons: a crown, a back button, and an action button with a distinctive orange stripe, adding a touch of style to its otherwise monochromatic design. It uses a quick-release pin system with horns on each side, allowing the use of standard 22 mm wide straps. The Coros Pace 4 Pro has a 1.47-inch screen, one of the largest in the sport watch market, with the screen occupying 61.5% of the case. The screen resolution is 466 x 466 pixels, or 317 pixels per inch, and is equipped with an AMOLED display. The screen brightness can reach up to 2500 cd/m² in daily use and 3500 cd/m² during training. It includes a light sensor to adjust brightness according to the environment and an "always-on" display mode for quick information access. The Coros Pace 4 Pro is compatible with both Android and iOS smartphones and requires the Coros app for full functionality. It has 64 MB of RAM and 32 GB of storage, along with a comprehensive set of sensors for health and fitness tracking, including optical heart rate, barometric altimeter, GPS, accelerometer, gyroscope, compass, temperature sensor, pulse oximeter, and electrocardiogram. The GPS supports multiple satellite systems, including GPS, Galileo, Glonass, Beidou, and QZSS, with dual-frequency compatibility (L1+L5) for improved accuracy. The Coros Pace 4 Pro features a 447 mAh battery, offering 50% more autonomy than the Pace 4 according to the manufacturer. In practice, it can last up to 21 days in connected mode or seven days with the always-on display. For activity tracking, it lasts 40 hours in "Max GPS" mode or 60 hours in "High GPS" mode. It includes Bluetooth connectivity for pairing with smartphones, headphones, and third-party sensors, and is compatible with Wi-Fi for updates or map downloads. However, it lacks an NFC chip, so it cannot be used for contactless payments. The Coros Pace 4 Pro has been available in France since September 22, offered in black or white, with several strap options: black silicone, white silicone, black nylon, or white nylon. The white nylon strap version will be released in late October 2026. Priced at 449 euros, it is 180 euros more than the Pace 4 (269 euros) and 50 euros more than the original Pace Pro. It remains 100 euros cheaper than the Garmin Forerunner 570, which is priced at 549.99 euros and lacks mapping features.
