What's up guys, I was given one of my grandfathers watches and was wondering if someone may possibly know the model, or could tell me a little bit about it. A few things I've noticed:
1. Minerva is written in all print on the face.
2. The case back is blank, possibly replaced?
3. Speidel band - I'm assuming this was put on post-purchase.
Attached are some pictures, thank you.
