Thx for the positive replies...
So we can assume that these
"Alaska II" time pieces stayed at least
1263 days (3 years 5 months 16 days) aboard Salyut-6
Even if these
"Alaska II" chronographs & cases were left aboard Salyut-6 , we can count a period of
1764 days ( July 29, 1982 = re-entry of the Salyut-6 space station) flown-in-space...
🙁 Although I'm
missing a few (important) pieces of the puzzle (if returned to Earth, where are these chronographs today ? Moscow ?Baikonour or StarCity museum ? )... several various magazines (spaceflight & watch-related content) show interest in bringing this remarkable story... which I'm glad to offer on a 100% voluntary & unpaid basis... as the story has to be told to celebrate the upcoming 40th anniversary of the Soyuz 29 spacewalk ( July 29, 2018 )
