This clock was an estate find and is in amazing cosmetic condition. I am in no way a clock expert, however mechanically I do not see any reason why this clock would not run. The gears and the chimes spring and all the mechanisms appear to be in very good condition. Since I am not a clock expert I am selling the clock as is because I have no key to try and get it running. The approximate measurements are 15" X 8.5" X 7 1/4". Upon viewing other clocks, I would like to add that a piece... of the neck may be missing and therefore is a bit shorter. It does not take away from the equisite beauty of this piece and goes unnoticed without direct comparison. I will add 2 more photos of top/neck piece.
