Any insight into this vintage AP

[watchlooker101]

Hello AP experts,

I have a friend who is incredibly interested in this specific vintage AP (picture attached). I said I'd reach out to the AP community to see if anyone could identify it, which might make the hunt a little easier.

Anyone here know anything about this model?

Thanks so much in advance!

Looks like an Ultra-Thin model from the 1960s with a 2003 calibre (probably wears very small like ~32mm)
