Octopus Watch v1 has a simple layer of protection on the screen, whereas Octopus Watch v2 Motion Edition has two layers of protection.

You can put a screen protector. More info.
/!\ Attention: the protection comes sandwiched. Make sure you peel off both sides and use only the piece that is in the middle (see red arrow below):
