Chronostop (First Generation)
Introduced in 1966, the Chronostop used a single pusher and central hand to time intervals of up to 60 seconds. Its youthful styling and deliberately simple operation later led to driver-oriented versions with rotated dials. Reference ST 145.009 defines the first generation and provides a practical search key for this distinctive vintage OMEGA.
