Mid Century Omega Seamaster Manual Chronostop Watch

Mid Century Omega Seamaster Manual Chronostop Watch. The Chronostop was launched in 1966 as part of the Seamaster line, with a 42mm case, but then transferred to the Geneve collection in 1967 in a smaller case size. The watch is powered by a manual-wind movement with a simplified chronograph operated by a single button at 2 0’clock to start and stop the red centre-seconds chrono hand. Once the button is pressed to stop the hand, continuous pressure on the button is required to read the time. Once the time is noted and the button released, the red hand returns to the 12-position. The watch has a black oxidised dial with applied polish steel hour marker batons, and there is an internal fixed bezel displaying a Tachymetre scale.
