These are watches rare and unique with their single push stopwatch function. The mechanism is designed so that the user presses the pusher once to start the orange stopwatch hand. Then, presses it again and holds it down to stop the stopwatch and read the time elapsed and, finally, release the pusher to reset the hand to zero. This is a particularity of the 865 Caliber introduced in 1966 and only 124,000 were ever made. This Seamaster Chronostop model was released shortly before the Olympic Games in Mexico City 1968.
