I’d like to see where Omega corporate publicly stated that the 3861 retains the “endorsement of NASA.” (I believe separately Omega corporate has said they subjected the 3861 to the standardized tests, etc.)
An OB salesperson, in contrast, have been known to say
all kinds of things.
That much I do understand: though the distinction here, I think, is that those prior “update” versions have been issued by NASA to its astronauts and taken on missions/EVAs/etc., no?
For the reasons you state, it seems likely NASA may do the same in the future with the 3861, but that nonetheless remains to be seen in the future.
This doesn’t in any way diminish the 3861 as an incredible watch; but it does separate perhaps the marketing from the (present) facts.
