Hi: I've heard that the aging rate of crystals gets better as the frequency gets lower. The idea is that the more mass in the crystal the less an atom here or there will be missed. So the 32768 Hz watch crystals should be very good compared to a 10 Mhz crystal.
Does anyone have any data on watch crystal aging? If there was a known aging rate then it could be backed out in the countdown circuit resulting in much better accuracy.
