I have a Citizen GN-4W-S Auto Gents wristwatch that probably dates from 70's-80's.
The glass assembly has fallen out of the watch and I would to repair it. I am just not sure how to do this.
The glass fits into a metal outer ring which then sits into the watch. The ring is bevelled as is the mating watch case.
There is a very small amount of movement when the glass is offered up to the watch so I assume it requires some kind of sealer ring or is it sealed with a type of glue? It may be both of those ideas.
If anyone has an answer I would be very grateful.
