Need help!!! (Hublot) 1915.NE10.7 real or fake??

[Sea-dweller11]

Hi there,

I purchased my hublot from a very close friend. The watch came with warranty card, manual and box. But for some reason I am having a hard time believing it is real. I paid $3,800 for the watch. Everything seems to be legit, but engraved on the rotor is "hublot". Most hublots I have seen have "hublot Geneve" engraved on the rotor. Is this a fake? Or just an older model? I am not too familiar with hublot at all and am unaware if their older models included Geneve on the rotor.

ps. I brought up my worries to the friend that sold me the watch and he said if it is indeed a fake he would give me a full refund, but he received it from a family member and doesn't believe it to be a fake.

Thanks so much

I am on a business trip until Friday the 14th and I will load pictures then. In the meantime I uploaded a picture I found online with an identical caseback to mine.
