Yes, we all know that Instagram and Facebook are killing the traditional discussion forums -- and the spammers are not helping much, either -- but this is the sort of question that used to be the stock in trade of this forum, and so many other ones.

And yes, again, these postings remain searchable and are used all the time, when people are researching these detailed, "nerdy" questions.

I wish I had some dials and serial numbers to share, but I can't think of any, at the moment.

But thanks for this posting . . . worthwhile to keep the old discussion forum going, for postings like this (and for the sake of preserving the 100,000 previous postings over the last 16 years).

: It’s so great to see a forum post like this. In the “olden
: days” of the forum, there were extensive community research
: projects about vintage Heuer variations and evolution. It really
: was a communal effort, with different people contributing to
: extending the knowledge base of Heuer watches.

: After the rise of Instagram this serious, community based analysis
: has largely disappeared, so it is great to see your post.

: I’ll do some checking of my watches and come back; I think it is
: a useful part of the debate if it happens on a searchable forum,
: but maybe I am an old fashioned guy in that opinion.

: Thanks again for your post
