JG is right, it is really important to get started with a new vet for your new bunny so you have a baseline exam established, determine whether you like the vet before you have any sudden need, and know how healthy you new little guy is. If you look at the top of the Q&A forum, you'll see posts for finding a good vet in your area. Exotics are what bunnies are listed under by most vets. A watery eye can be an indication of several issues, sometimes teeth problems, or blocked ducts, or allergy to something like your choice of litter. Have him checked.
Also, read over the Bunny Info. sections thoroughly to set his habitat up in optimal conditions. For example, they do not need bedding, just litter in a litter pan. And never use cedar or pine shavings. Stuff like that.
Oh, and we like to see photos!
