Inking Chronographs
The inking chronograph was invented by Nicolas-Mathieu Rieussec, watchmaker to King Louis Philippe of France, in 1821. It operates by means of a hand composed of two parts. The lower part is fitted with an ink bowl and the upper part with a thin needle which, when activated, compresses the lower part to release a trace of ink on the dial to give a visual read-out of the elapsed time.
It is interesting to note that the following two inking chronographs bear succeeding movement numbers and were both made in 1879 and sold on 24 May of the same year.
