Junk Store Bulgari - Real or Fake?

[Heywatchthis]

So I am at one of my local junk stores looking for "stuff" when I move to the jewelry case. This particular store likes to save all their watches and then bag them in zip locks to sell as a lot of 5 - 10 watches or so. It is usaully all junk but I like to look through them on occasion. Today, a Bulgari watch caught my eye in one of the bags and I thought I would buy the bag just for kicks (you can't open it in the store). I thought for sure it would probably be an obvious fake, and it probably is to someone who knows Bulgari Watches. However, I can't tell for sure. So, I thought I would throw it out to the folks who would know. The back has a model number of BB 23 GL with a star next to it. Below that is "P31970". I tried to shoot a couple pictures but they didn't turn out too well. I thought someone out there might be able to see an obvious flaw making it a fake? Or, perhaps tell me I might have found that ocassional good item?
