Hi all,
again, there pop up a special and rare dial modification, only seen in the 85xxx range. The round six of the rindt dials.
I still think it is an early prototype dial. Heuer may ordered some test dials and then mounted them at the start of a new watch execution.
Talked to a professional collector guy here, knowing some old Heuer watch maker, he saw this differentiation some times in the past too.
It is great to see that we get more and more deeper in the things that happened at Heuer
