Stylish watch. Expected wear for an item of its age. If you press the little plate into the batteries when the back is off, then a few areas light up, as in the images. I have no idea if this plate is original to the watch.
It looks pretty clean inside, but when I tried a battery in it, it did not work properly. Therefore, I have no idea what the issue could be.
