Nice article in Wikipedia. Didn't see any familiar names in the reference list, though.
Seems to me inhibition compensation is useful for compensating for the variation in purchased crystal frequencies, but not for temperature compensation. Also seems to me that a watch spends 2/3 of a day at wrist temperature and 1/3 at bedroom temperature, which varies with the seasons. Would a ceramic capacitor crafted for a certain temperature coefficient work? Can the fork have a crafted tempco?

In my case ?\200? not so much. FWIW, mine drifts pretty badly. It's in an aftermarket stereo, and I don't remember when I bought it (I moved it from my previous car). I assume that all quartz clocks and watches these days use "inhibition conpensation". https://en.wikipedia.org/wiki/Quartz_clock#Inhibition_compensation _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
