Just based off of what I have seen, the “West Germany” made version uses the self winding movement. It also has a different seconds hand with a rectangular tip. The ad says self winding as does the dial.

The “t swiss t” (French on the case back) uses the mechanical movement and has an arrow tipped seconds hand. Which, is the one I have pictured on my wrist above. The ad for this does not mention self winding or automatic, like the other ad above. The dial also says “invincible” in place of “self-winding.”

Edit to add: I also just realize I’m only talking about one specific reference out of that entire display. The mechanical and automatic versions, despite where they were made, had enough slight differences in both appearance and functionality that I can see why they had different names.
