Raketa Baikonur

When Raketa ”Baikonur” is used in the space station, the automatic winding will not work in the absence of gravity, and the cosmonaut will therefore need to wind it up by hand using the manual winding function. This function includes a very special system that disengages the wheels of the automatic winding mechanism to avoid their premature use while the watch is in space.
The 24 hour dial enables the wearer to tell night from day in the space station and can also serve as a solar compass by pointing the hour hand towards the sun. This is useful if the “Soyuz” space-craft should fail to land at the right spot in the taiga and its electronic compass ceases to function (as has actually already happened)
