Google has released a substantial software update for its wearable lineup, and it feels like one of those updates that quietly reshapes how you end up using a device day to day. The December 2025 rollout adds two new gesture controls for the Pixel Watch 4, Double Pinch and Wrist Turn, while also introducing a noticeably faster Smart Reply system for both the Pixel Watch 3 and Pixel Watch 4. The changes are really aimed at those small, practical moments when your hands are already busy, whether you’re carrying groceries or, as I sometimes do, trying not to burn something on the stove.
Key Takeaways
- Double Pinch Gesture: Pixel Watch 4 users can now tap their index finger and thumb together twice to manage notifications, control music, or stop timers.
- Wrist Turn Gesture: A quick wrist rotation allows users to silence calls or dismiss alerts without touching the screen.
- Faster Smart Replies: The Pixel Watch 3 and 4 now use an on-device Gemma AI model for messaging, making replies two times faster.
- Offline Functionality: The new Smart Reply system works independently of the phone, allowing for quick responses even without a Bluetooth connection.
- Availability: Gestures are exclusive to the Pixel Watch 4, while the AI messaging update covers both the Series 3 and Series 4 models.
Hands-Free Control with New Gestures
The standout addition in this update is the introduction of the Double Pinch and Wrist Turn gestures for the Pixel Watch 4. These gestures tap into the watch’s accelerometer and gyroscope to detect subtle muscle movements, which sounds technical, but in practice it just means you can get things done without actually poking at the screen.
The Double Pinch action calls for tapping your index finger and thumb together two times. It’s a tiny motion, almost forgettable, yet it triggers a range of actions depending on what’s currently on the display. Users can scroll through notification streams, pause or play music, snooze alarms, and manage timers. Google has also mentioned plans to expand this gesture so it can answer or end calls, something that might feel surprisingly natural once you try it. To make learning the gesture less confusing, the interface will show subtle hints whenever a double pinch can be used.
The Wrist Turn gesture has a slightly more instinctive feel. By turning the wrist away and then back again, users can silence incoming calls or dismiss alerting notifications. It’s the sort of gesture that becomes second nature after a few tries, particularly in situations where you want to avoid drawing attention to your watch, like in a meeting or a quiet conversation.
On-Device AI Upgrades Messaging
Beyond these physical controls, Google has also given the messaging experience a meaningful upgrade. Both the Pixel Watch 3 and Pixel Watch 4 now rely on Gemma, Google’s open-source AI model, to power Smart Replies directly on the watch hardware itself.
Previously, responses often depended on cloud processing or the phone nearby. The switch to an on-device model cuts that delay noticeably. Google says the new system is twice as fast as the earlier version, and it also uses less battery. The fact that it all operates locally means users can still generate contextual, high-quality replies even when the watch isn’t connected to a smartphone. I think that might be one of the more underrated parts of this update because it changes how reliable the watch feels in those moments when connectivity drops.
Accessibility and User Experience
These updates also address some of the long-standing challenges of using a small touchscreen. One handed operation can be tricky, so adding gestures that rely on natural movements will likely help users who have limited mobility or simply have their other hand occupied. The inclusion of the Raise to Talk tutorial reinforces the idea that Google is trying to guide users toward mastering these small but meaningful interactions.
All gesture options can be customized through the Gestures menu in the settings. Users can enable or disable individual controls and adjust how often on-screen hints appear. It’s a small level of customization, but perhaps enough to let people settle into what feels comfortable without overthinking it.
