Fitness band/watch for swimming

Hi All, Need your suggestions for fitness bands. Requirements - Sleep tracking, bamdinton calorie tracking, heart rate, spo2 or any other health monitoring.

My main aim w it is to track my workouts/sport sessions (incl. swimming) and step count. Which one would be the best?

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.

Recommend a good smart watch for fitness tracking. It should look classy and shouldnt be overpriced.

I'm searching for a good smart watch within a ₹3k budget. I'm wavering between Noise and Firebolt. Does anyone have any suggestions?
