Hi,
I have a Philips quartz clock that runs on 4.19 MHz.
In spite of the high frequency it still runs for years
on a C cell.
Can any of the quartz crystal gurus explain why this
frequency was chosen? I believe that this clock was
supposed to have better than usual accuracy.
Philips always had a high level of engineering excellence.
cheers,

Your clock's crystal is more likely 4,194304 Mhz, which can be divided down
to 1Hz, which is used by your clock to keep time to the second.
