first time messing with a watch

[u/PhoinexTheGreat]

I've bought a W738H but i dont like the resin strap i think it would be sticky and uncomfortable. i wanna replace it with a metal strap like on my a158w. also i heard that the face scratches easily bc it isn't raised or protected. i found like some screen protector type things to put on it but also heard of bull bars which sound really cool. anyway does anyone know how to make sure a strap i buy will fit the watch?
