The Google Pixel Watch 4 is built for the active professional who wants a smartwatch that keeps up without constant charging. Use it to track your morning run with dual-frequency GPS for accurate route mapping, then check your heart rate and sleep trends to recover smarter.
You get a 40-hour battery that lasts through two days of workouts and meetings. A 15-minute charge in the side dock gives you 15 hours of use, so you never miss a step. The 10% larger Actua display is 50% brighter than the previous model, making it easy to read in direct sunlight. Scratches are less of a worry with Gorilla Glass protection.
Gemini AI assistant handles questions and hyper-relevant quick replies without you pulling out your phone. Loss of Pulse Detection and satellite-based emergency SOS add safety during solo hikes. Control your Nest Cam, reply to texts, and listen to music with Pixel Buds—all from your wrist. It's an Android companion that focuses on what matters: your health, your day, your peace of mind.
