Fitness band/watch for swimming

Need solid recommendations for a smart band/watch that works perfectly for swimming - which can track laps, time, calorie burnt, etc during swimming. Other usual features like heart rate, step counter, battery life, etc too.

Would be great if you could share your personal experience!

Didn’t really find any good reviews of bands for swimming like Fitbit etc. and Apple watch seems costly - still thinking if I should go for Apple.

TIA!
