From the manufacturer:
Following on from SpaceWalker, the satellite tourbillon dedicated to Alexey Leonov’s 1965 space mission, Louis Moinet is now unveiling its second creation commemorating the great Russian cosmonaut’s 1975 Apollo-Soyuz adventure – the first joint space mission between the Soviet Union and the United States of America. Soyuz 19 was launched from Baikonur Cosmodrome, and Apollo from Cape Canaveral, Florida, before the two met up for mankind’s first ever rendezvous in space.
