I see what you mean about the numbers, they really stand out. Also on the movt, the incabloc on the regulator is strange looking plus the bridge shape is a quick tell. At least from what I can see in those pictures.
Excellent choice for a project watch for modding. You could learn a bunch in the process as well. I'd like to try some mods on a future watch just need to get some time.
Hmmmm...project watch. Just what I needed, another excuse to add to the collection!
