sorry to copy your style (although nowhere as good)a bit in my response/more questions, but i wanted to cover the multiple sections without missing anything.

Not a problem J! I wish more people took the time!

even though i'm sure your correct, as your knowledge and experience is miles above my head, the dial, to me, looks very similar to the autavia gmt. what significant differences am i missing?

Ok, it's really REALLY subtle... On the Heuer GMT, or at least mine, the Sub dials go all the way to the luminous dot at 3, 6 and 9. On the Glycine and Nivada there is a little bit of black space between the sub dials and the luminous that isn't there on the Heuer (or at least mine).

another great piece, thanks for sharing! could it be another case possibly of using the same suppliers?

Ah, this is fun! Like show and tell in Kindergarten... To answer your question, yes, this could be another example of using the same case suppliers.

as for my other question(s). excellent response, greatly appreciated!

Ah, You're welcome, like I say, I enjoy this...
