I need to replace the damaged strike train great wheel, so I need to identify the movement. There's a stamp on the back plate that reads "Div.Pat.u.G.M.angem."

It looks like a Regula #1. Div.Pat.u.G.M.angem is patent information in German.

Thanks Vernon,

Question: Do you know if the great wheel from a more modern Regula 25 movement would replace the damaged one in a Regula #1?

Sorry Mitch but I don't. Maybe someone else can answer. What is wrong with it?

The #25 will be smaller.

There are a few catalogs around that show photos of older cuckoo chain wheels. BFI (Black Forest Imports) comes to mind. Merritt's only offers chain-wheels for the #25 and #34.

There is 'new old stock' around but knowing exactly what you are buying will be problematic.

Most of the older cuckoo chain wheels can be repaired.

A 25 wheel will not work. It's internal widths from plate to plate is 3mm less than one of those. I was going to count the teeth. But I figured it wasn't necessary after I realized it won't even fit between the plates.

The wheel has been mangled and the chain jumps off when it is pulled.
