вот этого я никогда не смог понять,бох с ней с водозащитой и латунью,но почему Стрела без пружины на балансе,вредительство???

Скорее всего, как было на Venus'е, так и скопировали. :)

Была и "Стрела" и "Луч" тонкий (поправьте если ошибаюсь)

Очевидно, какое-то количество "Спидмастеров" попало во "Интеркосмос" во время подготовки "Союз - Апполон". В "Омеге" летал не только Архипыч, но и Горбатко и Джанибеков.

Вот текст с сайта музея "Омеги":

The next step in the story was to come the following year when the Apollo-Soyuz mission was being planned. This was to be the first time that the American and Soviet space agencies would work together and in many ways, it signalled the end of the "space race". It was at this point that OMEGA discovered that the cosmonauts were using the Flightmaster. They adopted the Speedmaster for the mission when an “OMEGA” representative told them that “if they wanted to be on time with the Americans they should wear the same watch”. On the flight there were a total of ten watches used, all of which were Speedmasters; however, Tom Stafford wore the 18 Ct yellow gold Speedmaster Deluxe he had received after the Apollo 11 lunar landing in 1969. All the other watches worn by the astronauts were the standard NASA issue watches equipped with 321 calibre while all the cosmonauts wore the newer ST145.022 with 861 calibre.

From this point the cosmonauts wore Speedmaster on their missions including on the Salyut Space Station. A notable exception to this was Speedmaster 125 worn by Vladimir Djanibekov in 1978 on his Salyut 6 mission

Была (есть) еще одна Omega у Архипыча, подарочная. Золотой кастомный Constellation на кварцевом калибре Megaquartz, c русским календарем с подарочной гравировкой.

This special watch was given to Leonov immediately after the Apollo-Soyuz mission and he's worn it (literally) every day since. It is one of five ever made in yellow gold, and made exclusively for him with the day wheel in Russian.
