The 105.012 Speedmaster was the watch selected as part of the official kit for the Apollo missions.... An extremely collectable reference, they feature the 'new' style twisted lugs, gorgeous stepped dial (with applied logo), the first appearance of the Professional inscription and of course the sought after Lemania 321 calibre . Incredibly exciting that this is the same reference that accompanied Neil and Buzz on their most famous holiday. This example is in fantastically crisp condition with nice wide bevels on those lyre lugs.
