On another irritating note, the screw down crown of my Eberhard now won't screw down.
I noticed it had popped out yesterday while I was wearing it, and you know, you think "did I screw the crown in after I wound the watch?" So I screwed it back down. But this morning, the crown just kept spinning when I tried to screw it down, so suspect the threads have stripped. Will have to go have a word with Rob the Watchmaker at some point, and hope either he or I can magic a new stem and tube from somewhere.
The crucial bit will be finding out what the base calibre is, although AFAIK Eberhard made their own movements back in the day. This could potentially be tricky.
Botheration.
