Omega Speedmaster 105.003 ‘Ed White’ from 1966
This Omega Speedmaster 105.003 is also called the Ed White Speedmaster, this is because he was the first American astronaut that did a space-walk back in 1965 during the Gemini IV mission. This Speedmaster features a Cal. 321 manual wound movement which was made by Omega and is the last non-professional speedmaster with a 38mm case. This was also the last Speedmaster with a straight lug case and without the crown guards.
