I need some help - I wanna buy parts or a complete watch for build a 2201.50 franken. At the moment it is quite hard to find a used watch or case. So my idea is to buy a new rep and put the gen parts into this. So is there any rep of 2201.50 or 2209.50 from any factory to buy and worth to franken it, or do I have to wait for an used watch / case.?
