Electronics of Master Clock for Slave Clocks

Big old wall clocks that were used in facilities such as schools, factories and hospitals are very appealing and will probably never go out of style. They are very durable and almost never break down due to very simple mechanism they have.

This mechanism is actually pretty simple, it is just an impulse motor (two coils) and a couple of gears - no further complications. This is a blessing and also a curse for these antique clocks because for their operation they now require something called a master clock. Master clock is an electronic device that sends pulses to these slave clocks so that they can work.
