So, how much did these refurbished Bundeswehr from Sinn sell for originally when they were advertised? And how much are they worth now?

I took some quick and dirty pics of the one I saw. Basically it looks like any other Bundeswehr (and I have no reason to suspect it's a replica, since I trust the source and the watch seems correct). But it has a case back with no markings.

Here are the photos. Terribly sorry, but I was in a rush and only had the phone on me. But you get the idea. So what do you guys think? A refurb from Sinn?
