Hi,
It is a modern clock, probably 1970's or 1980's, produced in the style of a Vienna regulator made a century earlier. At first glance, the movement could well be German - lhe weights look to be good quality - I know Keiniger still makes some nice quality weight-driven wall clocks. However, the arrows on the dial indicating how to wind the clock, and the fact that each train is wound in the opposite direction to the others are two factors which are synonymous with an Asian copy, likely Korean. That would be my bet, what is more the carving on the case is quite crude, in my opinion. With that said, if it is indeed Korean and not German, it is the nicest Korean clock I've come across and I've never seen an example with apparently functional weights. Personnally, I would only buy it if you like it and the price is right, if you are prepared to take a chance and do a little bit of investigating - we need to see the movement to provide a more constructive, definite opinion.
Regards.
