1970's Seamaster Cosmic 2000
I have just acquired a 1970's Seamaster Cosmic 2000 which needs a bit of work. sometimes the min and hour hands stop while the seconds hand continues to run OK. I do simple work to watches if I have the correct tools and think this is probably a loose cannon pinion?? The problem I have is getting the case apart. I've read about a guy who used compressed air down the pendant tube to blow the back off but I believe with the correct press and dies the whole lot can be pressed out the front of the case. Any idea where I could get the correct dies or any other suggestions on how to split the case?
