From that picture you can't really see much. Look for brands like Omega, Tag Heuer, Rolex, and other brands people on here will probably list. Vintage men's divers are usually a good buy too.
And chronograph. But have three circles on the face. Just not the fossil one on the bottom right. They're going to have some extra buttons on the side too. Probably not the best description but I'm tired.
The one on the bottom right underneath that fossil looking one, looks good. And then maybe the ones in the top right corner That don't have the bands. But it is pretty hard to tell.
Nothing jumped out to me except that chronograph in the middle and the diver on the lower right side. It's hard to tell but it looks like mostly fashion watches to me.
