Movement
Longines 13ZN-12
Central-minute configuration of the manually wound 13ZN family, with separate central elapsed-second and elapsed-minute hands plus a twelve-hour register. Specialist sources distinguish it from split-seconds chronographs and state that it lacks flyback; the base 13ZN name alone does not establish this configuration.
