Specifications
About this watch.
The Omega Speedmaster Professional ref. 105.012-66 is one of the most iconic and collectible vintage Speedmasters. Produced in 1966, it is powered by the legendary Omega Calibre 321, a hand-wound, column-wheel chronograph movement also used in the watches worn by NASA astronauts during the Apollo missions. A highly desirable feature is the original “Dot Over 90” (DON) tachymeter bezel, where the dot is positioned above the number 90. This detail significantly enhances the watch’s originality, authenticity, and collector value.
