Omega Speedmaster Mark III - ST176.002
The Mark III is important. It is the first automatic Speedmaster. Omega clearly were inspired by the Flightmaster that came before it. Omega referred to the shape as “anatomical” - it was designed for comfort and to conform to the shape of the human wrist, like the Omega Dynamic of the same period. Real life experience would indicate otherwise as the Mk3 is a very big watch!
Omega promoted the Mark III heavily alongside the traditional Moonwatch and the Mark II. Omega advertised it from 1972 through 1975, and it came in multiple dial colors. Omega labelled some later versions of the Mark III “Professional”.
