Guilherme, thanks for your research!

But... these watches were never completed and delivered... as you can read in my post.

So no portuguese military has ever received one: for this reason none remember it.

Maybe they were ordered officially, but also "not officially" from a group of officers and, as dictated by the story, never paid and never picked up?
Who can say?
Sure, in '80 none make 4 different dials and stamping caseback for a "kit" that costs under 100 $!

: I cannot discuss the subject as an Heuer expert but had the
: opportunity to ask some man that served in those countries about
: the watches featured in the pictures. From the small sample of
: 12 soldiers none had ever seen such watches. They all mentioned
: that soldiers did not receive any watch from the armed forces
: (and this includes man from army, navy, air force, and commando
: special forces).
: One of the men served 2 commisions as a helicopter pilot in
: Moçambique and said that from what he recalls even pilots did
: not receive any watch from the air force and had to buy one from
: their own money.
: He is a fairly informed man and also made a few curious comments:
: - It may be possible that this watches were only given to jet
: fighter pilots (the higher ranked pilots) or high rank officers.
: - The watches don´t seem to have been in Africa because they look
: pretty new.
: - He found strange watches issued to Cabo Verde and São Tomé e
: Principe because the armed foreces presence was minimal, with
: only a small company in each country.

: I also had the opportunity to ask the Portuguese Air Force Archives
: about the watches and they have sent me a reply. I have sent the
: first photo and they cross-checked it with photos from the
: archives and found no match. I also asked if they had any
: register of Heuer watches issued to pilots or other officers and
: they said that in their gear registers they found no information
: about Heuer equipment.
: At least officialy those watches were not included in the Air Force
: equipment. I can forward the reply from the chief of the
: archives if someone wants to red it.

: Previously I had asked about the period of the watches because in
: the early seventies there was significant turbulence in the
: Armed Forces and the theory that they may have been ordered but
: not paid for is plausible.

: Greetings from Lisbon,

: Guilherme
