Rolex 14k Jubilee Bracelet

[CrossSider]

Hi ! I'm new here and though you guys could help me with this one haha

I bought a jubilee bracelet on eBay to replaced my worn out bracelet on my Rolex
But the clasp on it seems very weird to me on the picture and not sure the model number fits as well, The Hallmark doesn't fit either, I'm pretty sure it's a fake I just bought, I'm I wrong ? Would really appreciate the help cause I'm really stuck on this one.
