Indeed - I guess made using the same instruction set.
My godfather’s Congreve Rolling Ball Clock looks wonderful, but by his own admission, is a terrible timekeeper!
The one above is a bit more reliable.
Thank you for the welcome.
Back in the 70's and 80's when parts for Seiko movements were plentiful, Seiko recommend you changed the barrel complete I think every 5 or 7 years. These days you have to take the barrel apart and clean it all and put back as parts are more likely to be obsolete.
Welcome! That is a pretty Alpina. I like its style. I too would be very careful about polishing it up at all. If you decide to though, there are silver polishing cloths you could use. I wouldn't use anything stronger than those, if at all, and I'd use a very gentle touch with them.
You could put a polishing cloth on the rounded end of a little paintbrush handle and just sort of "spot polish" the vine patterns and border. That might work. But I'm still leaning toward leaving it be.
