The back of the Dial is approximately 5 7/8'' in diameter (photos 9 & 10). Winding Post holes are 3 3/16'' on center (photo 11). Winding Post holes to the Center Shaft hole are 2'' on center (photo 12). The 4 Mounting Screws are included (photo 15).
The Dial Face has recessed black painted Arabic Numerals and are easy to see. The silvered Face has wear throughout and heavier wear around the winding post holes. The wear includes tarnish and corrosion. The Bezel open's and closes but you have to work with it to get it to snap. The Hinge is tight. No chip's or cracks to the Convex Bezel Glass. It does have some light scratching when holding it under a light but looking straight on it is clear.
