5 3/8 wide on face, edge to edge. It has been kept in very nice condition. Face shows no issues. Sides have a couple of spots here and there. See all the pictures for more details. The clock runs and chimes, but the chimes do not correspond to time. Clock should be attached to a wall for the chimes to work properly.
