Google has unveiled the Pixel Watch 4, a major update that aims to strengthen its Wear OS ecosystem with a brighter, domed display, longer battery life, new health tools, and a first of its kind satellite communication feature for emergency use. The new model arrives as Google also debuts the Pixel Buds 2a and the Pixel 10 series, with preorders already live and general availability set for October 9, 2025.
