"Master Clock System" Patek Philippe, Genève, Model L4011. Made circa 1975. Very fine and rare, Integrated Electronic T3 Master Clock System with independent minute and seconds comparators in a five-piece tower. Notes The three clock units measure the time separately. Each one is equipped with a quartz-crystal oscillator and electronic dividers. The results are compared in the control unit which is built in the time unit. If one of the clock units shows a difference, it is automatically switched off. To increase precision the clock system is synchronized each second by the time signal from the Prangins observatory, near Geneva.
