As I mentioned a while ago Polar have another watch in the pipeline called the M200. It looks like this is very close as the FCC posting is in, may even be this week.
It’s a round faced watch and looks pretty basic to me. Although there is colour in the picture, I would guess that is a surround since it’s in every picture. That means quite a small basic screen, which the name M200 would line up with as it’s a base model.
