To me, the term Chronometer describes the precision and accuracy of the timer, not the method used to obtain that accuracy.
In the 21st century a mechanical watch is only a chronometer when afforded 'special dispensation' by the self-regulating watch industry. It's a title, not a description.
The purpose of hacking was more to do with synchronisation between watches than ultimate accuracy.
Before the preponderance of accurate time sources brought about by electric (50/60Hz movements) then quartz (tens of thousands of Hertz and up), how would one set a watch? Time pips on the radio? Ring up the speaking clock? Compare to the town hall/railway/church clock?
How precise is that going to be?
And in any case, imagine beign the only person with a superbly accurate watch in a town where everyone was wearing ones that ran fast or slow or not at all....firstly, how would you know?
and second, would it help or hinder your life?
