Late 19th Century French Marble & Slate Mantel Clock

I have been asked to sell this by a villager.

Black Slate With Contrasting Tan / Green & Rouge Marble Accents

This is a heavy clock, has a couple of marks on the right hand side. Personally I'm not sure about it's time keeping and chiming, albeit I have added a video of it (I think it might be missing a weight). So I highly suggest getting the clocked serviced prior to use, as did say the owners. Comes with original key.
