One UI 9 Watch is Samsung’s implementation of Wear OS 7 for smartwatches. It debuted in July 2026 in the second half of 2026 alongside the Galaxy Watch 9 and the Galaxy Watch Ultra 2, and delivers a slightly refreshed UI, new health and fitness tracking capabilities, and faster access to AI assistants such as Gemini.
One UI 9 Watch design
The software uses slightly more vibrant colors across the interface, including widgets, and adopts a slightly smaller default font size so most UI labels fit on a single line and reduce scrolling. It introduces a Raise to Talk feature for quicker access to AI assistants like Google’s Gemini. Samsung also merged the Double Pinch and Shake gestures, reserving Double Pinch for positive actions (answering a call or confirming an alert) and Share for negative actions (like declining a call or dismissing an alert). Some stock apps, including Samsung Health, have received minor design upgrades.
Features
Select Galaxy Watches running One UI 9 Watch can display Daily Cardio Load, Hearing Health, Heart Health, and Vitals. The Trail Run exercise mode in Samsung Health adds climb guidance, turn-by-turn route tracking and navigation, and water intake alarms, and users can load routes via GPX files. Cycling features now include the ability to compete against a user’s past records with real-time comparison metrics. The software supports diving and can show real-time dive metrics such as elapsed dive time, current depth, and water temperature through the built-in Depth app on select models like the Galaxy Watch Ultra 2. With the Mares app, some compatible watches can display additional diving data including ascent and descent speeds, No-Decompression Limit guidance, real-time nitrogen absorption monitoring, and adjustable gradient factors.
Release and compatibility
One UI 9 Watch debuted with the Galaxy Watch 9 and the Galaxy Watch Ultra 2 in July 2026. Samsung plans to release the update to compatible Galaxy Watches before the end of 2026.
