Think of how to improve your sleep or work out more efficiently. That way, you can improve your health and workout performance. On the Galaxy Watch 7, you can smoothly switch between various apps like WhatsApp, Spotify, and Strava.

I'm happy with my smartwatch. For health reasons, a watch with fall detection and an emergency alert function is quite handy. If you're not ready for a senior emergency button around your neck yet. ;-) Lots of features, but I haven't explored them all in a few days.

This watch has a small watch case. We recommend these if you have a maximum wrist circumference of 15cm. Measure your wrist circumference 2 fingers above your wrist joint, just above the protruding part. Is your wrist circumference larger? This watch may not be the best for you. Read which watch case size we do recommend.
