Hi all! I bought this Polerouter 204612 locally in Norway a couple of years back and I had it serviced this year. I then found out that the movement has been changed at some point. Today it has a cal. 69, but it ought to have a cal. 218-2. I bought a donor watch the other day, so hopefully I will have the right movement in a couple of months. The crown is also wrong, but I have not managed to source one yet. Does any of you know where I can source such a part? Do you have and suggestions to any European, vintage watchmakers that might have it? It should be a big crown.
