My 2021 quartz Timex loses 15 seconds per month. Accuracy of Quartz Movements vs. Mechanical Movements Quartz movements are far more accurate than mechanical movements, typically only losing a few seconds per month. There are also High Accuracy Quartz (HAQ) movements that negate the effects of temperature changes thanks to thermocompensation, therefore only lose around ten seconds .In the realm of luxury watches, quartz movement is often enhanced with advanced features like thermocompensation, ensuring unparalleled precision. Precision. The precision of quartz movement is one of its most significant advantages. A standard quartz watch can achieve an accuracy of ±15 seconds per month, far surpassing most mechanical watches.Quartz watches are accurate to within 1 second per day. Your watches show that accuracy. . CA-53, and DBC-32) and they all keep to within about 5 seconds of time signal per month. I also haven't had them that long (Since the end of last year). So my guess is that one of your watches is old, or the battery is getting run down and it isn't .
Improvements in accuracy in watches and clocks is largely the story of the pursuit of higher frequencies, from 36,000 vph high frequency mechanical movements, to tuning fork movements like the Accutron, to quartz watches. The most accurate watch in the world, the Citizen 0100, has a specially cut quartz crystal with a frequency of 8,388,608Hz . I've got a 20+ years old Lancer with a Ronda 715 inside, and upon the two last months the accuracy was between +13s late and +17s late per month. So that makes about +0.45spd (I'll do more accurate calculations in a future thread). Therefore, left to run on their own, consumer-grade quartz clocks can drift by several seconds per month even in relatively temperature-stable environments (e.g., Lombardi, 2008). To overcome .
EDIT: correction-- its just as accurate at 15 seconds per month as indicated in the specs!! so moot thread, but I'll keep it up as there is good info! . If I extrapolate that for 12 months, for a quartz watch that's reasonable - better than a quartz watch that does +/- 180 sec per year. But not as good as a COSC Quartz that does +/- 25.2 .
Accuracy of a quartz watch ; The greatest virtue of a quartz watch is its high level of time accuracy. Time-keeping of a quartz watch is based on the crystal oscillator of high frequency (32,768 Hz). As for a mechanical watch, the minimum accuracy is ±several seconds/day; however, the accuracy of a general quartz watch is ±20 seconds/month.
