احصل على السعرThanks to the quartz mineral that vibrates at 32768 Hz (or 32768 times in a second). An electronic chip inside the watch then uses this vibration signal to determine 1 second. This is one of the reason why quartz watch is so accurate – that is even if the quartz mineral is off by a few vibrations per second, it's still not that significant to make the timekeeping inaccurate.
