For those who are interested in superior technology, start reading about quartz movements and the piezoelectric effect. Citizen Watch Company recently release the most accurate quartz watch ever, accurate to 1 second per year . Contrast that to the mechanical watches that Rolex—one of the best mechanical manufacturers—produces and the best they can do is an accuracy of about 1 second per day . Hundreds of times less…
This does not prevent them from being feats of engineering, because of the technology limitations, and the need to show off (ever saw a tourbillion watch?). I would compare them to Fabergé's eggs of our time.
