Google introduced Pixel Watch 4 in August 2025, then announced Double pinch, Wrist turn, and updated Smart Replies for Pixel Watch 3 and newer in December. The gestures let you control supported watch tasks without touching the screen, while the updated on-device model generates suggested replies even when the watch is not tethered to a phone. Google says the new model is faster and more memory-efficient than its predecessor; those are Google’s figures, not independent test results.
Pixel Watch 4 launch and feature timeline
The timing matters: the named gestures and updated Smart Reply model were not all launch-day features. Google announced Pixel Watch 4 on August 20, 2025, and announced the gesture and reply update on December 9, 2025.
| When | What Google announced |
|---|---|
| August 20, 2025 | Pixel Watch 4 launch, including contextual AI-powered Smart Replies. |
| December 9, 2025 | Double pinch and Wrist turn gestures, plus an updated on-device Gemma-based Smart Reply model for Pixel Watch 3 and newer. |
Google said Pixel Watch 4 devices would be on shelves starting October 9, 2025. That was the launch announcement’s expected availability date, not a future date.
What can Pixel Watch 4 gestures do?
Google’s December announcement describes Double pinch and Wrist turn as ways to interact with the watch without touching its screen. Supported actions include handling notifications, alarms and timers, controlling music, selecting a Smart Reply, and answering or ending calls. Google’s current product page summarizes examples such as double pinching to answer calls or snooze alarms, and using a wrist flick to silence calls or dismiss notifications. Exact availability and behavior may depend on software updates.

Google says on-screen hints can show when Double pinch is available. These are specific watch controls, not evidence that the watch interprets arbitrary movements or adapts to an individual user’s gestures. Use the watch’s prompts and current Google help information to see which actions are available on your device.
How Smart Replies changed
Google says Pixel Watch 3 and newer watches use an on-device Gemma-based language model to generate Smart Replies for Google Messages and more, including when the watch is not tethered to a phone. The reply-model update is therefore not exclusive to Pixel Watch 4.

Google describes the model as twice as fast and nearly three times more efficient in memory usage than its previous generation. These comparisons come from Google; the research for this article did not independently test them. The update is about generating suggested replies on the watch, not a guarantee that every reply will suit the conversation.
Compatibility, connectivity, and buying context
Google lists most phones running Android 11.0 or newer as compatible. Bluetooth and Wi-Fi functions such as calls and notifications require the phone nearby; LTE functions away from the phone require a compatible carrier and activation.
