I'm still getting familiar with Uwatch3. I haven't used all of the features yet. I'm happy with the ease of looking up daily health related information. I appreciate the alerts for text messages and phone calls. I can't believe how little battery is used. 100% charged, the day ends and it's still 100% charged. Even if I record my ride my bike for a couple of hours, the battery is still 96% charged! Nice! Relatives and friends are impressed by these things, too.
