Hi folks, Searching for seals that are part of the pusher on a Valjoux 92 Chronograph. The watch is a Nivada Grenchen CASD. Here is a pic of what I am looking for. The seal should not have a hole in it as far as I understand. It’s a dome style seal that sits on pusher rod and the pusher cap goes on the end. It’s not the o ring that actually seals the case. Thanks.
