But the dial specifically, the writing, the constellation fond, Swiss made, the markers star position all looks perfect. And as you mentioned the price for these later constellations are not sky high to facilitate such high quality fakes. So I would go for original.
PS magic words, more pictures, will attract the attention of the experts in the forum. And if it was a fake they would have ignored all that and come to your rescue, that’s another indication it’s an original.
