Today would be a good day to delete your Facebook account:
Here is why:
When I saw fake Alpinist, I immediately thought who would invest money in an extremely high quality fake of an inexpensive watch. There can’t be much margin or profit there.
That element of doubt is the main reason I buy from reputable retailers or ADs.
The first photo attached by OP, actually it is two different photos merged together (I took it both). That's why left watch looks bigger.
I've had both watches in hand. What's worried me the most is the fact that you couldn't fully screwd the crown. It leaves small gap between case and crown (because of the shape of the case - too round probably).
In my opinion it is possible that the there are some parts genuine and some not.
Hopefully somebody will open it and check it what is inside.
On the photo below both watches lie side by side.
