This 1965 Omega Speedmaster 'Pre-Pro' watch was submitted by Balthasar de Pury (instagram user @balthasardepury).

'One of the favorite timepiece in my collection, 1965 Omega Speedmaster 'Pre-Pro' (so-called 'Pre-Professional', the contracts were signed with NASA to become their official timekeeper in 1965, from 1966 the word 'Professional' was added on the dial) equipped with the famous caliber 321! The first Speedie I bought, six other followed since then and the addiction of collecting never stopped growing ;)'
