One of the lightest sports watches I've tested doesn't sacrifice features for build

"When the Coros Pace 3 was released in 2023, I praised its lightweight form factor at just 30 grams. The all-new continues that trend with some significant improvements at nearly the same weight, while including a brilliant AMOLED display, new optical heart rate sensor, and a microphone for recording training logs and voice pins. Also: I tested the best sports watches in 2025: Here are the latest and greatest watches, no matter your budget Coros also added a new left-side button, similar to the Nomad and Apex 4, for specific functions within sport modes. Despite the sub-$250 price, the vivid AMOLED display is also a touchscreen so you can use the buttons and the touchscreen to navigate the UI, with the top right button acting as a dial that's easy to scroll through the various menus and widgets."

"Software feature improvements in the Pace 4 include menstrual cycle tracking, connected smartphone music controls, and a flashlight utility that has three levels of brightness for the AMOLED display. By the way, this flashlight utility is now available on other AMOLED Coros watches, so go update your watch if you have a different Coros model. Unlike the comparable Garmin Forerunner 165 base model, the Pace 4 supports on-board music support, but it's only for downloaded MP3 files -- not offline subscription music."

"In order to have a more accurate training readiness value, I recommend capturing your metrics while you sleep. Past Coros watches have been a bit chunky, and while I like big watches, they're harder to sleep with. The Coros Pace 4, by comparison, is so light and sleek that I barely even notice it on my wrist while I sleep. Additionally, I was pleased with the sleep stage results when compared to other watches and my Oura Ring 4."

The Coros Pace 4 preserves the lightweight roughly 30-gram form factor while adding a bright AMOLED touchscreen, a new optical heart-rate sensor, and a microphone for recording training logs and voice pins. A new left-side button enables sport-mode functions and the top-right button serves as an easy-to-scroll dial. Software updates include menstrual cycle tracking, connected smartphone music controls, and a three-level AMOLED flashlight utility now rolled out to other Coros AMOLED watches. On-board music is limited to downloaded MP3 files rather than offline subscription services. The watch's slim design supports comfortable sleep tracking to improve training readiness metrics.
