Perhaps it went like the ingenieur 'SL' Jumbo model from the 70's-80's which was a big version of the then SL. Apparently only 1000 were sold, not a popular watch. I love them.

I've always like the current ingenieur, not as much as the 80's one, but thought it was far too big. I have however just discovered that they did a mid-size model at 34mm, the same size as the standard men's Ingenieur of the previous version. Might look out for one.
