Great advert.

Oh for an optional 'stainless steel band' at $15!

: I found a brochure scan introducing the watch that Arno sent me,
: but it doesn't make the claim of first with date wheel. Might be
: my memory but I could have sworn it did, or maybe there is
: another out there...

: I'll carry on looking for the other ad, if it indeed exists. Even
: if there were other chrono movements with date wheels out there
: at the time, Valjoux didn't have one, so Heuer would have to
: have looked for a different partner. If it was nowadays, there
: would be all sorts of kickbacks and exclusivity deals going on
: between the watch and movement manufacturers, I wonder how those
: relationships were back then.
