The Apple Watch has best in class health sensors + fitness monitoring. Cycle tracking, blood O2 sensing, ecg function are all truly valuable.

I bought a watch for myself, my parents and my girlfriend. The prompting and social aspects of the “close your rings” exercise tracking have already led to a ~10 bpm decrease in my girlfriend’s resting heart rate, suggesting a marked improvement in her cardiovascular health.

Personally, I find the Apple Watch somewhat ugly, but the fitness features are worth the sartorial limitations!
