Overview
- Wear OS 6.1 (BP4A.251205.005.W7) is rolling out to Pixel Watch 2–4 with December security fixes.
- Pixel Watch 4 adds double‑pinch and wrist‑rotation gestures that are enabled by default with onscreen hints and a tutorial.
- The new gestures cover system actions including scrolling notifications and lists, silencing alarms, managing timers and the stopwatch, pausing music, selecting replies, and handling calls.
- Pixel Watch 3 and 4 receive upgraded Smart Replies powered by a local Gemma‑based model that works offline and is about twice as fast with nearly three times better memory efficiency.
- AI replies launch only in English, Pixel Watch 2 gets no new interaction features, and the original 2022 Pixel Watch has already reached its last update.
