Cosmonaut Vladimir Dzhanibekov enjoyed his Omega Speedmaster chronographs. 1978 Soyuz 27 training photos of Vladimir Dzhanibekov show him wearing a “ 125 years Omega Speedmaster ” reference ST 378.0801. The “Speedy 125″, issued in 1973,  was the first chronometer-certified wrist chronograph. Dzhanibekov certainly wore a Speedmaster 145.022  on Soyuz 39 to Salyut 6 in March 1981, the “Intercosmos” mission with Mongolia. This image shows Dzhanibekov wearing a “ 125 years Omega Speedmaster “ during the Soyuz T-6 mission aboard the Salyut 7 space station in June 1982... (Photo: RKA/TASS)
