You nailed it CG. Same family of movements, but the Ronda 7004N. Renato used the 7004 big date in many of the retrograde models.
Funny mentioning the Concept T. I was looking for a Seiko Monster I couldn't find and found it inside one of Wing's old android 3-slot cases along with this auto Concept T.
Forgot the Concept T wasn't a chrono. so that would've ruled out the 8040. I like the 7004n and have it in a Renato or two like you said and a few Invicta's. I like the dial work done on the auto Concept watch.
