Thanks for the depth-write up SJX.
I’m not sure if it’s only me but when I first saw pictures of the new Ingenieur vintage, it made me think of PP 5107P. IMHO, They share the same dial design and look absolutely the same-- black dial, baton indices, dauphine hands and date window at three o’clock. Perhaps, only case dimension and bezel are a bit different. It would be interesting to see how PP fans would react about this.
