The Omega Speedmaster Professional 145.012 was the very last Speedmaster model to run on the legendary Lémania-based Caliber 321 manual-wound chronograph movement. This reference is also the last one to have the dial with applied Omega logo and long hours indexes as well as the DoN (dot over ninety) bezel, as attractively exemplified by the present lot. Several astronauts used the 145.012 such as Michael Collins, Alan Shepard or Tom Stafford. 
This piece is homogeneous with a well-preserved naturally patinated dial, matching the faded bezel and a case with well defined lines and fitted on a 1039 bracelet.
