This type of work is done on a cnc milling machine generally. If on angled surfaces likely a 4 or 5 axis machine. Big bucks.
That caseback is flat enough to do on a 3 axis, the engraved surface of the rotor seems ok too.
Like this? PM me.I will put it in the mail. Alternatively you could go on ETSY. Search Russian watch movement..or watch mechanism. Get a shovel full of used parts movements from Ukraine,it's where this one came from.
