Anyone Know What's Inside Of These Envelopes?

I'm just a new guy...but should the question at this point not be "Is there any value in the envelopes not being opened?" If not...then open the damn thing! I suspect having the cards provides some value and historical 'coolness' to the whole package but the increased perceived value of the un-opened envelope is probably negligibly higher than just the card itself.

The case is also sealed, with paraffin. Would you open the watch case?
The value to me is not monetary, it's the fact that nothing has been
touched since it was packed at the factory 43 years ago.I'm sure someone
knows what's in it. I can wait.

Hi John - I'm with you; I'd take the same approach. A watch can be unique for any one of a number of reasons - originality/NOS is one of them, and the number of watches that remain truly original, sealed, and NOS dwindle as years go by. An item is only new once, and there are plenty more fish in the sea out there for ones to wear.

I'd say enjoy this one, as it is! 😀

cheers,
Mark

JiminOz gave the best clue I think.
I started Googling and here is what I came up with-
Found an eBay UK ad for this:
It's the same year as the Speedy. 32xxxxxxxx
So I went to a light and bulged the envelope to try to
let some more light into it. I saw 2 things.
It was 1 light color and one dark color split exactly like the
booklet below. And I could make out the word Omega and the symbol in
the exact same location as this one.
My iPhone pic of the envelope bend is below.

Being a new guy, you won't quite understand how obsessive compulsive the long time vintage collectors are over crap that would seem trivial to normal people. It's okay, and actually good that you have some normal left in you. However, this situation is something that would cause a 4+ year collector to chew his nails to the cuticles over. 😵‍💫 We're like that. 🙄

Maybe some Speedmasters were sold with them?(Certificate of High Precision)
They seem to have movement number on Booklet also, at least on this one I found.

gator
now you have me confused, Speedmaster, Seamaster, Moonwatch. ?

and this-

So I would expect to see Operating Instructions, Certificate of High Precision and Guarantee booklets.
With which watch?

got it Ash, thanks didn't know that about 125.
I can see through the envelope it's 1/4 white on top 3/4 red, with Omega and symbol printed in the white section.
Envelope has movement number on back. Has to be a Certificate of High Precision or
Speedmaster facsimile. The fact that no one knows what it is, is all the more reason not to open it.
Not trying to mess with you guys. I really thought someone would know when I started this
thread. Is it possible this one was Chronometer rated?
