i just won a lucky draw garmin heart rate monitor chest strap.

the problem is i dont have any smart watch.

1) which smart watch can read HRM ?
2) cheapest as possible
3) can read "Pace"

Garmin

depends what sport u in

if doing road running, if want cheap can go for amazfit t rex pro

less than rm350 with voucher

You don't need to go all out—look at the Garmin Forerunner 45 or 35. They’re pretty affordable and will pair with your chest strap for heart rate, plus they track pace.
