Rolex buckle help needed!

The 16mm Rolex buckle market is a jungle! Any advice from the experts would be more than welcome. Here I have two specimens, the first one used, the second one brand new. Any comments from the experts would be more than appreciated. Both legit? Both fake? To me, the first one doesn´t look good, but since my knowledge of these buckles is very limited, I would be happy to stand corrected!

With prices on bracelets going crazy, and concidering the current interest in 36mm watches, I guess we are going to see more of these buckles in the future.
