Is this the only picture you have? More shots of the movement, case, dial and so on would likely allow us to provide better information. Judging by this single photograph, it looks to me like the clock could perhaps be all original, but again we need more to go on in order to decide.
I found this for sale online. The seller states the movement and dial have been changed to electric. I have asked for more photos but none have arrived. It is over 150 mile away or I would check it out. If it is something important, I would go get it.
yes, I understand the movement is probably quartz. I am curious as to what the clock is, having never seen one of this type. (I have seen a few) Also, I have a sweep seconds pin wheel movement that needs a home.
Sorry if I am missing something, but I'm not sure what information you are looking for. You ask 'what the clock is'. As the original movement has been removed, we can really only talk about the case. But I can't see anything unusual about it, so perhaps you are asking about some other specific point?
The case appears unusual to me. It is not like any grandfather clock I know of. American, English, Northern European, or German. I can't say what furniture style it is. It does not appear to be antique, nor modern. I thought it may have been an industrial or scientific regulator.
