Many decades ago when digital displays and "quartz" clocks were a novelty, I built a table clock and presented it to my father a watch nut. He regularly teased me that my "digital" clock was slow or fast compared to his 25 year old Omega that he bought when I was born!

>When you look at what a very good pure mechanical watch can do it's pretty impressive. Quartz was out for quite a while before it could run anywhere as good as a top notch mechanical. They actually have standardized (had?) yearly testing of watch accuracy. The actual ran for a number months at various temperatures and orientations. The term "certified chronometer" apparently has meaning in Swiss law.
