> Quartz watches are superior in almost every metric: they cost less, tell better time […]

This is true to a certain extent, in that an equivalent level of accuracy is generally cheaper with a quartz watch than a mechanical watch, but it’s not true across the board. I have a relatively basic mechanical watch that’s dramatically more accurate over a month than the Timex Easy Reader I bought for $25. High accuracy quartz watches are more expensive than you might think.
