Strap like Smartwatch 3 for normal watches

Hello, I tried a Sony Smartwatch 3 and I was impressed by the quality of the strap. It is the black plastic strap. I really like how it feels in my skin.

Anyway, I didn't like android wear, so I went back to my Pebble. But I wonder, do you guys know any universal strap for normal watches like the sony smartwatch? I'm talking about material and quality. I know the strap is only for somy smartwatches, but I want to know if any other manufacturer makes similar straps.

Thanks.
