I was wondering if the G-shock waveceptors have a feedback loop?
Let me clarify.
Without signal reception my GW810 specifies accuracy of +/- 15 sec.
With signal reception the time is spot on (of course!)
Now, my question is this. Does the G-shock use any error in time (when signal reception is good) to "tune" the circuit so the +/-15 sec is improved when there is no signal calibration? i.e. a feedback loop that automatically calibrates the watch for even better accuracy when there is no signal reception.
