But as when an authentic watch is shown,
Each man winds up and rectifies his own,
So in our very judgments
— John Suckling, epilogue to Aglaura (1637)
(quoted in David Landes, Revolution in Time)
I’m surprised to learn that fairly advanced spring-driven watches were already in use well before the Huygens pendulum clock (1650s).
Even an inaccurate personal source of time is liberty from tyranny in a time-based labor market.
