OmegaThis OMEGA Speedmaster Professional is a manual-wind stainless steel chronograph wristwatch dating to 1977. It is equipped with the calibre 861 movement. The 42mm stainless steel case features a black matte dial with luminous baton indexes, along with an external tachymetre bezel.
The dial layout includes subsidiary registers for constant seconds at 9 o'clock, a 30-minute recorder at 3 o'clock, and a 12-hour recorder at 6 o'clock. It uses luminous baton hands and an arrowhead center chronograph seconds hand. The watch is presented on a stainless steel bracelet and is accompanied by an extract from the archives. The reference 145.022 follows earlier Speedmaster references 105.003 and 105.012 and was the first reference to incorporate the painted OMEGA logo and shorter hour markers, reflecting specific design changes in the Speedmaster Professional line established after its initial 1969 launch.
