From the 2nd pic, I could see the leather is very soft, as well as the texture appearance.
I had seen a fake one (for around HK$3300) and compared with my real one. I could see the leather felt like vinyl when touched, and its so hard that the bag looked like a box even it is empty inside. Also the hole and the hardware dont match. So whoever uses a fake one is unwilling to let others touch the bag.
But anyway the best way is to have it checked by reseller
