I liked the book 'Longitude' very much - an excellent story!

"I think I may make bold to say that there is neither any other 
Mechanism or Mathematical thing in the World that is more 
beautiful or curious in texture than this my [longitude] Time-keeper."
(by John Harrison)

aren't such clocks already a kind of 'digital' clocks, 
using ecapement mechanismn to force the drive to run 
stepwise alike run by dripping water?
