Tag Heuer Watch Question?

I just bought a Tag Heuer watch yesterday. When I got it home and got it out in the sun so the light his the face i've notices that there is one part on the face of the watch that has a "foggy" look too it. It's not crystal clear like the rest of the face of the watch. It's just a small spot, but it upset me b/c i paid so much for the watch. It doesnt look like a scratch of anykind and some kind of light has to be hitting it in order for it to show. Does anyone know what this might be and how it can be fixed. I have to drive 45 minutes to go back to the store i got it from, while do if i need to, but I dont want to waste a trip. Would a jewler be able to buff that out?
