This strap is much lighter and prettier than the vinyl strap that comes with it. I got a rash from the original. This does not stretch, but can be adjusted to any size. Each link has a size. I tried others but the pins that attached it to the watch didn't hold. This one is durable, comfortable, light and safe. The only downside is minor. You should wear it slightly higher/closer on your arm so the sensors can read your biometrics. If it slips and spins, you won't lose your hand, but it doesn't accurately measure steps, heart rate, etc. I wear it 24/7. It is very comfortable and can be worn up or down.
