Frumer does good work, and Tokugawa era timekeeping is interesting because
it used western-stye clock movements to represent seasonally variable
hours, which makes it culturally irrelevant to this list since it
emphasized kairotic timekeeping rather than precision and uniformity.

There is a large period literature on ³dialing² which not only included
sundials, but all sorts of ways to measure time from celestial objects
using angles. Discussions of trigonometry, surveying, navigation, and
³dyaling² in relationship were also quite common during the period. These
could be
It all depends on how far back you want to go. With mechanical
timepieces, even before the pendulum there was Jost Burgi¹s astronomical
clock which achieved a precision of a second, and is reported to have been
accurate to that level based on astronomical measurements. Tycho Brahe
tried to
