Bradley German Made Vintage Mini Alarm Clock (read description)

Bradley German Made Vintage Mini Alarm Clock. All it has for markings is the “Bradley” on the front. And on the back “Germany” in engraved on the bottom. I must add that the winding mechanisms both seem to work perfectly. You can easily set the time and the alarm works and sounds great. But it allows you to wind and wind to make it actually tell the time, but it doesn’t seem to actually make the hour and minute hands move. I don’t know clocks…but if someone knows if this means it’s broken or just needs a quick fix please lmk! I just like to be totally transparent
