A Samsung Health app notice says Vascular Load changes in the US will take effect in late July 2026, signaling One UI 9 Watch is close and hinting a beta could open around then.
The notice also says Samsung will add a new Blood Pressure Trend feature on the upcoming Galaxy Watch 9 and Galaxy Watch Ultra 2, replacing Vascular Load in that market.
One UI 9 Watch is expected to run on Wear OS 7, which Google recently showcased, and to focus on major under-the-hood improvements rather than a broad visible redesign.
Based on Samsung’s past rollout pattern, the beta may extend to older models such as the Galaxy Watch 8 and the 2024 and 2025 Galaxy Watch Ultra.
