Samsung is rolling out the stable One UI 9 Watch update to the Galaxy Watch 8 series. The software is based on Google’s Wear OS 7 and is initially reaching users in South Korea. The rollout covers the Galaxy Watch 8 in 40mm and 44mm variants, along with the Galaxy Watch 8 Classic in 46mm. Samsung released the update to both beta testers and regular users, ending a testing cycle that began in August.
One UI 9 Watch introduces a refreshed interface designed for Samsung’s round smartwatch displays. Samsung has also improved navigation gestures and made watch-face setup simpler.
The update strengthens Samsung Health with a redesigned dashboard and new health insights. Users can access Daily Cardio Load, sleep vitals, heart-health tracking and improved workout guidance.
Samsung also added a ‘raise to talk’ gesture for quicker access to digital assistants, including Google Gemini. The feature lets users activate the assistant by raising the wrist, reducing the need to press buttons or navigate menus.
The stable build carries the identifier BZJ7. Reports list firmware versions including L325NKOU3BZJ7 for the 40mm Galaxy Watch 8 and L335NKOU3BZJ7 for the 44mm model. The update is large, with reports putting the full download at about 2 GB. It also includes the October 5, 2026 security patch.
The South Korean release signals the start of Samsung’s broader One UI 9 Watch deployment. The company is expected to extend the update to more markets, although it has not announced a global schedule.
The update gives Galaxy Watch 8 owners a more polished software experience and deeper health-focused features. It also aligns Samsung’s wearables more closely with Google’s latest Wear OS platform.
