Samsung has started expanding the stable One UI 9 Watch update for the Galaxy Watch 8 and Galaxy Watch 8 Classic, bringing its latest smartwatch software to users in the United States. The update is based on Google’s Wear OS 7 and introduces a redesigned interface, improved Samsung Health features, new fitness insights, and several usability improvements.
The stable rollout initially began in South Korea on November 8, 2026. Now, on November 10, Samsung has started expanding availability to the US. However, early reports indicate that beta participants are receiving the update first, meaning regular US users may have to wait a little longer.
One UI 9 Watch Update: Firmware Details
Samsung is distributing the stable One UI 9 Watch update with firmware versions ending in BZJ7.
The Korean firmware versions reported for the Galaxy Watch 8 lineup are:
- Galaxy Watch 8 40mm: L325NKOU3BZJ7
- Galaxy Watch 8 44mm: L335NKOU3BZJ7
- Galaxy Watch 8 Classic 46mm: L505NKOU3BZJ7
For US beta participants, separate firmware builds have been reported. The Galaxy Watch 8 Classic receives build L500XXU2BZJ7, while the standard Galaxy Watch 8 gets L320XXU2BZJ7.
The update package is approximately 2GB for regular users in South Korea. However, US beta testers are receiving a much smaller download of around 158.5MB because they already have most of the software installed.
The update also carries the October 5, 2026 security patch, according to update-screen reports.
