Originally made for a German nuclear power plant, this particular master timing system can control an almost unlimited amount of slave clocks and can be regulated to 1/1000 of a second. The internal quartz oscillator is designed to be further synchronized through automatic time control from the observatory. This backup system was radio controlled from a signal from Prangins Observatory near Lake Geneva. (decommissioned December 31, 2011.)

During the 1970s, Patek Philippe perfected its electronic master clock timing system and they were considered the most state of the art and accurate systems available on the market. The master timing system consisted of a highly accurate master clock with numerous ‘slave’ timepieces. Airports, train stations, and office buildings employed these timing systems to ensure that exact time was uniformly displayed. The systems were extremely accurate and featured solid-state master clocks with no moving parts (except for the hands, of course) and were designed to be protected from water, vapor, fumes and salt spray. An almost limitless number of slave clocks could be connected to the master clock, making it ideal for a multitude of locations, including hospitals, shops, laboratories and power stations.

The original retail price of one of these timing systems in the mid-1970s was approximately 14,000 Swiss francs.
