Samsung has started rolling out a major software update for the Galaxy Watch 8 series, bringing One UI 9 Watch based on Google's latest Wear OS 7.

Samsung has been testing One UI 9 Watch on its older smartwatches for quite some time now. While the latest Galaxy Watch 9 and Galaxy Watch Ultra 2 launched with Wear OS 7 out of the box, owners of older Galaxy Watch models have been waiting to get their hands on the latest software.

And now, after nearly two and a half months of beta testing, Samsung has finally started rolling out the stable update to the Galaxy Watch 8 and Galaxy Watch 8 Classic.

Samsung has started rolling out the update for both models in the US. The update carries firmware version L320XXU2BZJ7 for the standard Galaxy Watch 8 and L500XXU2BZJ7 for the Galaxy Watch 8 Classic. It also includes the October 2026 security patch and, as expected, is based on Google's latest Wear OS 7.

The update is reportedly around 2GB, although the download should be significantly smaller for users already running the beta version.

One UI 9 Watch brings more than just a new look

As for what's new, One UI 9 Watch is based on Wear OS 7 and brings several improvements. First up, there's a redesigned Galaxy Wearable app with a cleaner layout and simpler customization controls, alongside a reorganized settings interface.

You can also now swipe through different watch faces directly from the main screen without having to jump into a separate customization menu. Gesture controls have received an update as well, with double-pinch and shake gestures now grouped under a single toggle.

Samsung is also introducing several new health and fitness features, including Daily Cardio Load, which helps users better understand how much physical activity they're getting throughout the day. There's also improved sleep vitals monitoring, new heart health insights, and redesigned health charts that make it easier to understand your fitness data.

As for availability, the update has already begun rolling out to Galaxy Watch 8 and Galaxy Watch 8 Classic users in the US. If you own either smartwatch, you can check for the update by opening the Galaxy Wearable app on your phone and heading to Watch settings > Watch software update > Download and install.

Samsung hasn't confirmed exactly when One UI 9 Watch will reach other regions, such as Europe or Asia, but the rollout should expand over the coming days.
