Google is making it easier to do one-handed gestures on the Pixel Watch 4. With its December update, the company is bringing a double pinch gesture to the smartwatch. By pinching your index finger and thumb together twice, you can perform actions such as scrolling through notifications, pausing your timer or stopwatch, snoozing an alarm, sending the first Smart Reply, and playing or pausing music. The option to answer and end calls is coming "soon."
The Pixel Watch 4 also gets a wrist turn gesture, where you "quickly turn your wrist away from you and back," to dismiss calls or close other alerting notifications.
