·This was apparently a promotional item from 1954, placed in watch retail venues, marketing auto-winding watches with a highly technical and graphical explanation. It's interesting to see back when automatic movements were still considered "the timekeeper of the future!"
Previously, I have seen this type of transparent overlay in children's books or anatomy books, but it's interesting to see the movement cut away layer by layer, both front and back. And it's remarkable how different marketing was in the mid-20th century, when the general public was so excited by new technology. This almost feels like it could serve as a manual to illustrate movement assembly. Now it would just be about aesthetics and prestige.
I'm also a bit surprised that this plastic material has survived so well for 70 years.
If you have some entertaining promotional material, feel free to add it.
