Bvlgari real or fake?

[BVLGARI89]

Hello Guys,

Today while i was heading to work parked my car i found a bvlgari watch laying in the snow so i picked it up and research it and found its a really expensive watch so im just curious how can you tell if this watch is fake/replica from the looks of it i research it and it looks like a "BVLGARI ASSIOMA" take a look at the pictures tell me what you think ? also the watch looks like it could be an older model it looks sorta worn out. At the very bottom it reads [S.Swiss] and [MADE S] if that helps.

let me know if you need more pics. Thanks
