Google is giving the Pixel Watch 5 a new safety feature that could prove far more important than another fitness metric. Breathing Emergency Detection is designed to identify a breathing emergency. The Pixel Watch 5 already builds on Google’s existing safety features, including Loss of Pulse Detection. AdvertisementAnd, like the Pixel Watch 4, the Watch 5 also offers Readiness Score, support for more than 50 exercises, dual-frequency GPS and heart-rate tracking. For a smartwatch that spends most of its time quietly sitting on your wrist, Breathing Emergency Detection could be one of the Pixel Watch 5’s most meaningful additions.
