I'm repairing an antique pocket watch made by a craftsman in a small town in North-West Denmark. The face is a typical enamelled metal face, and it used to have two posts that were used to secure it to the movement.
One of those posts is gone - separated at what appears to have been a solder joint.
I'm now debating how to attach a new post to the back of the face. I can turn one from brass - but is there a danger that a soldering iron will melt the enamel on the front of the dial?
