In the world of vintage Speedmaster collecting, references 105.012 and 145.012 occupy a fascinating place. They were the last Speedmasters to house the revered Calibre 321, yet are often overshadowed by the better-known “Ed White” reference 105.003, and can resemble at a glance the far more common 145.022.

The 105.003 was the final model in the lineage to feature a 39 mm straight-lug case and non-“Professional” dial. Its successor, the 105.012, was the first to bear the “Professional” signature and the now-classic 42 mm case with lyre lugs—design hallmarks that remain largely unchanged to this day.

The example offered here looks better today than most things made in 1967. The original “DON” bezel has aged extensively, fading to a warm grey-brown tone that contrasts beautifully with the black dial. All tritium lume on the markers and hands remains intact, with a creamy patina that adds tremendous character. The case is exceptionally strong, likely having been lightly polished only once or twice in its lifetime. 

A proper old Speedie—one you’ll never tire of looking at.
