Unfortunately, amongst horologists I still encounter anything but consensus, just as Huygens must have experienced, introducing as his original ideas, his inventions and mechanical improvements, like the construction of the pendulum clock, his endless rope, the balance spring, the remontoir or his equation and maritime timekeepers.
