Always accurate to the exact second and automatically sets itself to the correct time at annual daylight saving changes! This remarkable atomic time pendulum movement contains a miniaturized radio receiver that receives a low frequency time signal broadcast from Fort Collins, Colorado. That signal enables the movement to self-correct every day so that it always shows the exact time according to the national time standard.
