    Not entirely true. Quartz mechanisms can differ in precision.

    They also can have solar charging, atomic clock sync, bluethooth

    But mostly true for cheap Casio watches and cheaper lines of G-Shock. They keep the time to a very similar precision.

      Barring actual manufacturing defects, the cheapest quartz crystal timing circuit on the market will be far more accurate than the very best Swiss watch movement, by orders of magnitude. A mechanical watch depends on a spring whose behavior is highly environmentally dependent - it will gain or lose multiple seconds per day, being affected by the orientation, vibration and temperature changes it experiences. A quartz watch will drift a few seconds per month.
