Clock Details
These are all units from ESE . ( www.ese-web.com
The top one is the clock itself, ES 185, corrected by geosynchronous satellite contact, not by radio signals.
This one is accurate to 10 nanoseconds to the master reference clocks run by the US and other governments.
It determines day of the years and the time.
Signals carried in a pair of wires (coaxial, twisted, Monster Cable, whatever) carry time to the other displays.
Which are also in my TV room and the watch closet room.
