Overview
- Pixel Watch 4 gains a Double Pinch gesture that can answer or end calls, pause timers, snooze alarms, control music, take photos, and select a smart reply without touching the screen.
- A new Wrist Turn gesture on Pixel Watch 4 lets users silence or dismiss incoming calls and other alerting notifications with a quick turn of the wrist.
- Smart Replies on Pixel Watch 3 and 4 now run on an on‑device Gemma‑based model that works without a phone or cloud connection and delivers about 2x faster responses with nearly 3x better memory efficiency.
- The December system update (BP4A.251205.005.W7) is rolling out to Pixel Watch 2, 3, and 4, though the new one‑handed gestures are enabled only on Pixel Watch 4.
- Google is surfacing context‑aware gesture hints with user‑controlled prompt frequency and is shipping a step‑by‑step Raise to Talk tutorial to improve Gemini invocation on the watch.
