AP 15300 blue dial - authentic or not ?

[gustavhaa]

Hello everyone.

So I've been on the lookout for a 15300 with the blue dial for a while now and I've done as much research as I could. Finally i've located one that seems to be in a fair condition, never had service and for a fair price. Only issue is, that it comes without papers. And since we are meeting in germany (I have to fly there) I would like to make sure before i go there, that the watch seems to be authentic.

So hope you can help me see if everything seems to be in fine order, Also if there is anything in particular I should know before the purchase.

Thank you very much guys !
