Pixel Watch 5 adds blood pressure and insulin resistance tracking

Google's Pixel Watch 5, announced August 12 and shipping August 20 from $399, uses sensor data and machine learning to infer blood pressure patterns and insulin resistance. The blood pressure model trained on over 1 billion minutes from 500,000-plus people, validated against 24-hour ambulatory monitors. Google's insulin resistance research appeared in Nature, March 2026. These are inference-based indicators, not diagnostic measurements.
