This weekend I took some decent pictures of the watch. It's a very strange but interesting little diver. E-mailed Fortis a while ago and this was their answer: "Dear Mr [...], thanks for your email. We went through all our Fortis catalogues and unfortunately we haven’t found some information about this watch. We assume that this watch is from the seventies. We are very sorry that we can not give you more informations. Best regards/mit freundlichen Grüssen/avec nos meilleures salutations Regula Ritter Sales & Administration FORTIS Uhren AG Lindenstrasse 45 2540 Grenchen SWITZERLAND" Anyone ever seen this kind of dial? No one is able to know something about it. Love wearing it though. All info is appriciated!
I am convinced that it is original. But like with all of (my) watches, I always want to know as much as possible about them. This one remains a bit of a mystery to me.
