William Strutt & William Wigston, Derby, England, c. 1828
The design by William Strutt of Derby from the late 1820s, was produced in small numbers by his friend,
William Wigston. The original production ran to only 20 pieces due to the
excessive cost.
Strutt enlisted the help of his lifelong friend William Wigston who was also a gifted engineer and gathered inspiration for his
epicyclic clock from the rotary machines being manufactured at the Wigston
factory. Only a limited number were produced as the cost was found to be
prohibitive and took too much time from the main function of the Wigston
factory. The first clocks were signed 'W. Wigston, Derby' (immediately
underneath) "wm. Strutt, Esqr, Invt' showing this to be a joint effort.
This example has that designation. Later the designation only had 'Wm. Strutt'.
It is not clear when the clocks ceased to be manufactured. William Strutt
died in 1830 and Willliam Wigston survived him by only five years.
The epicyclic skeleton clock, although unique to the horological world,
was never seriously expected to supersede conventional timekeepers. The
design was a radical departure from ordinary practice, and epicyclic or 'sun
and planet' gear embodied in the train, which serves the double purpose of
gearing up the escape wheel and at the same time gearing down the hour wheel
in a most ingenious manner, without the usual motion wheels for that
purpose.
