The device leverages a refined sensor array and machine learning, trained on over one billion minutes of health data from 500,000 individuals, to monitor blood pressure trends. A new metabolic feature analyzes heart rate, sleep, and physical activity to identify potential insulin resistance, providing users with monthly trend summaries. In Europe, the watch gains an emergency safety tool capable of detecting sustained drops in blood oxygen saturation to alert responders during breathing crises.
Beyond health, Google has deeply embedded Gemini into the user experience. The assistant can now handle offline requests for timers and workouts or provide context-aware suggestions, such as mapping a restaurant mentioned in a text message. Updates including flight information and arrival times now surface dynamically on the watch face. Performance receives a significant boost via the Qualcomm Snapdragon W5 Gen 2 platform, yielding 20% faster overall speeds and a 50% increase in RAM over its predecessor.
Physical upgrades include improved GPS mapping, which Google claims is twice as accurate as previous models, and refined sleep tracking that offers a 15% gain in precision. The watch supports up to 40 hours of battery life and comes in 41mm and 44mm sizes, starting at $399 and $429 respectively. Pre-orders are open now, with general retail availability scheduled for August 20.
