Samsung has started rolling out the stable One UI 8 Watch update to Galaxy Watch7 users in select regions, more than a month after the last beta. South Korea's beta participants report getting the build first; wider availability should follow soon.
What's new in One UI 8 Watch?
The Wear OS 6-based update revamps the watch experience with a refreshed interface and several new features:
- Now Bar for quicker access to apps and information
- Updated gestures and improved notifications for faster interactions

- Health and fitness upgrades including Antioxidant Index, Running Coach, Vascular Load, and Bedtime Guidance
Rollout details and the update package
The stable release carries build number L310XXU1BYI4 and is roughly 160MB in size. It also includes the September security patch. Users who joined the One UI 8 Watch beta in South Korea have confirmed receiving the stable OTA; broader distribution to regular users should arrive in the coming days.

Health features that actually help
