- Stable One UI 9 Watch is now reaching Galaxy Watch 8 and Watch 8 Classic users in the US.
- The update is based on Wear OS 7 and includes the October 2026 security patch.
- Samsung’s official changelog details improvements to Samsung Health, watch faces, workout controls, and more.
Samsung’s latest smartwatch software is crossing borders, but it’s still keeping the guest list short. Just hours after the stable One UI 9 Watch update began rolling out in South Korea, the Wear OS 7-based release is making its way to Galaxy Watch 8 and Watch 8 Classic users in the US. For now, however, only beta testers appear to be getting an invitation.
X user Larry White already downloaded the stable One UI 9 update on his Galaxy Watch 8 Classic. At just 158.50MB, it’s a much lighter package than the roughly 2GB download rolling out to non-beta users in Korea. That’s because beta testers have already done most of the heavy lifting, leaving Samsung with a smaller final update to deliver. The release carries firmware version L500XXU2BZJ7 and the October 5, 2026 security patch. The regular Galaxy Watch 8 gets the same update under build L320XXU2BZJ7.
