The pre-moon Speedmaster reference 105.003 is colloquially referred to as the "Ed White" Speedmaster because this model type and reference was worn by NASA Astronaut Edward Higgins "Ed" White (1930-1967) when he was the first American to walk in space in 1965.
The reference 105.003 is rare as it was only in production for around three years from 1963 and then superseded by the 'professional' reference version 105.012 which, famously, was worn on the moon landing in 1969. Typical features of the "Ed White" pre-moon Speedmaster are the straight lugs, no crown guards and just signed on the dial Omega Speedmaster without the professional signature.
This example has been in the same ownership since new and comes with the original International guarantee booklet stating its purchase on the 28th.2.1970.
The guarantee booklet is marked with reference number 145.003 which can be seen on other examples in the past from research.
This example reference 105.003 is stamped in the case back of this watch and is identical to reference 145.003.
