Sorry, guys, that I have not had time to engage in this discussion. It seems like all the facts are on the table, so I'm not sure what I can add to the analysis.

I have never owned one of these watches, and know virtually nothing about them. To me, they are just photos on the screen, although there is something that I like about the watch!!

Let me add that while I wrote about the "Heuer 100", back in 2016, I did not see or inspect all of them, and I did not authenticate any of the watches. So we have no evidence to put on the scale, from my involvement with that sale.

: Hello Colin.

: Thank you very much again for your reply.

: I really enjoyed reading it and learned a lot.

: The Heuer 3006 is a beautiful piece.

: I did some more digging, additional time in the office helped a
: lot, and I managed to find some more examples with this caseback
: style and the 13/1 marking.

: Now we look at eight watches which all share the same caseback and
: the 13/1 marking.

: Five of them show the 13/1 clearly, the other three had not so good
: camera angles or strange lighting, so you can not see the whole
: caseback.

: I have these pics in higher resolution, as far as I could get them
: from various websites, but compressed them to fit them all in
: one picture.
: Anyway, I think you can see that they all share the same caseback.

: Please have a look at the pics I attached below.

: Especially interesting is the watch on the down right corner, the
: one with the bracelet on the stand.

: These two pictures are from TheHeuer100 Auction which was hosted by
: Crown & Caliber in 2016.
: Jeff Stein personally looked through the watches offered in this
: auction.

: He lists this exact watch in the OTD guide to the Heuer100 and it
: is still visible at the Heuer100 website.
: The OTD guide shows only the front of the watch, but on the
: Heuer100 site you can look at some more and larger pictures.

: And there on the Heuer100 website you can see:

: - same case

: - same pushers

: - same caseback style

: - same writing on the caseback

: - same thick tachymetre scale (which fooled you an Mathis in my
: first post - the „gap“)

: - same dial

: - same hands

: - my conclusion: same watch

: Of course this does not solve the question for the „Automatic“
: on the back of my watch.
: But let´s forget the „Automatic“ for a moment.

: Would you agree that we can say now, that it is a fact, that there
: are 2 caseback executions for the Ref. 13-1?

: I think i found enough evidence to establish this and for me it
: looks like the reference table for the 13-1 should be updated.

: Would love to hear the thoughts of Jeff Stein on this topic.

: I am also still looking forward to read more input and thoughts
: about this from all the knowledgeable members here.

: Greetings,

: Hermann
