Nice looking range of watches, with a vignetted dial, date at a nicely symmetrical 6, and very classical index numeration.
But
I am not convinced this is an Autavia - that seems to be cynical brand engineering to give this new range a leg-up.
It certainly isn't an Isograph, that has been the type of Rotring technical drawing pen that I first bought in 1982.
Shame it is 42mm, this would be so much nicer at 40mm.
