Recommendation for band/watch

I am looking to buy a band or smart watch for my wife Primary metrics that it should track are below: -steps -sleep time with sleep stages data -Resting heart rate -heart rate variability I am already using fitbit 4 for the last 2 years but have heard that it does not have a service center in india, so I'm not sure if i should again go for fitbit. Budget - preferably within 20k but can extend Also, if anyone has used garmin vivosport 4 or 5, please share your experience.

Please suggest something other than Apple watch and Galaxy watch. I'm not interested in having a smart watch. I just want to track my fitness metrics (HR, sleep metrics, stress etc). Any reliable band you can suggest? Something you have or heard about.

Looking for something for my dad, should have close to accurate readings and have a long enough battery life (he's bad at keeping stuff charged). Ideally within 20k. Pls suggest.
