Hi,
Recently the pusher for my Seagull 1963 decided to fall off, without me knowing about it. I have done a little searching but since this is a personal watch I don't want to spend unneeded money on several pushers in case my initial choice does not work. So, I included some measurements and i hope somebody could be able to help. I don't know too much about pushers, but from looking at the remaining one I can see that the protruding part of the pusher screws into the head.
PS: the outer diameter of the actual pusher is 3.95-4mm.
Any help is appreciated, thanks!
