Apple Watch SE 3
$199 (reg. $249) on Amazon
Having owned multiple Apple Watch versions and having used the features, I think the Apple Watch SE has the best amalgamation of useful features (step and heart monitoring, VO2 Max measuring post-exercise, fall detection) at the best prices – great options for your parents (heart health monitoring, including Afib monitoring, fall detection) or your teens (GPS location, cellular function that enables calling, alone with all the health features)
