It features advanced sensors including electrical and optical heart sensors, blood oxygen, and temperature sensors, which allow it to detect high and low heart rates, irregular rhythms, sleep apnea, and even signs of hypertension. The addition of ECG capabilities and a comprehensive sleep score makes it an excellent health companion beyond just fitness tracking.

The watch offers many useful features like fall and crash detection, emergency SOS, mindfulness apps, and medication reminders, making it a comprehensive health and safety device. Some drawbacks include the 24-hour battery life necessitating daily charging for heavy users and the requirement of an iPhone for full functionality of some advanced health notifications. The price tends to be higher compared to simpler heart rate monitors. This watch is best suited for users seeking a multifunctional smartwatch with top-tier health and fitness tracking, strong safety features, and excellent connectivity in a stylish, comfortable design.

Design-wise, the 44mm aluminum case and sport band offer a comfortable fit for most wrists, and the always-on Retina display keeps the screen visible without needing to lift your wrist.
