The back of the Dial is approximately 5 13/16'' in diameter (photos 11 & 12). Winding Post holes are 3 3/16'' on center (photo 7). Winding Post holes to the Center Shaft hole are 2'' on center (photo 8). No Mounting Screws included.
The Dial Face has recessed black painted Arabic Numerals and are easy to see. The silvered Face has some corrosion spotting and staining. The outside perimeter of the Brass Bezel has some corrosion and tarnish as well. The Bezel open's and closes smooth. The Hinge is tight. No chip's or cracks to the Convex Bezel Glass. When holding it under a light the Glass does have a scratch across the center but when looking straight on it is clear and almost impossible to see.
