Will jump in quickly as I need to run and can write more later.
Adding to what Rob wrote, all quartz movements are not even remotely the same quality. Most Jump when moving, not all. Some have a sweeping movement like mechanical. Also much difference in anti-magnetic qualities, number of jewels and entry price points just to name a few.
Since the first quartz movement in 1969, much has happened including some quartz watches now having a $4000 price entry point.
Must run, more later, great topic.
