Maybe a tad off topic: as we have seen the forefather of the 3536 let's see
one of the offsprings here: the 3719, reaching back to the roots of the very
first Aquatimer from 1967 with the underglass turning bezel - the 3719 being
the ETA-Valjoux based day-date chronograph version in the steel execution, one
of my favourite watches ever, the possible "exit watch" if it would ever
happen. Same size and case design as the 3536, 120 m WR - that is more than
enough for most. A fantastic piece. Hopefully we'll see some time a reissue
with the 69xxx movement inside, without steroids resulting a larger case and
with an improved clasp with quick-micro-adjust feature of today's IWC clasps.
I love this watch!
