Every video I see on some introduction to time-keeping history says things changed when quartz was discovered. I remember commercials for watches actually bragging in marketing campaigns about quartz time-keeping or whatever it is called. I don’t know what about quartz (is it an element) made it so important for keeping accurate time.
Also, I wasn’t sure what flair to put this under. I can add another if someone has a better suggestion.

When a current is applied to it vibrates at an extremely consistent frequency, which is what you need for accurate time keeping, a consistent frequency of something. Springs have to be wound up regularly and can change their springiness as temperature changes, pendulum clocks are fairly consistent but won’t keep consistent time on a boat. Quartz vibrating also isn’t really affected by outside factors
