Good morning everybody, I hope that someone can help me to understand something more about this watch but I do not find the way to post pictures. It is a Perseo watch with a Cortebert 720 calibre. I know that Cortebert worked with Perseo for the watches of the Italian Railway during the Mussolini time and that later in the late 60`s I believe, Cortebert bought Perseo and went on producing its watches. My questions about this watch are because there at least 2 things that I find interesting about this watch, the first is the Cortebert logo on the backside of the watch and the second is that this watch have indexes while the most of Perseo watches that I can find around have numbers all around. I think that this Perseo could be part of a limited edition. Can anybody help me? Thank you in advance.
