He could answer questions put to him by his colleagues when
they were faced with the difficulties involved in watch com-
plications. He could see at a glance the faults that prevented
his fellow-watchmakers from achieving their aims, and help
them to improve their precious time-keepers.
He spent his whole life firmly rooted to his family home. He
died in Le Locle in 1826 after working for almost 80 years to
perfect his art, the art of the watchmaker.

For many years, he devoted most of his time to developing
a reliable and strong automatic winding mechanism (around
1760). In doing so he certainly cherished utopian ideas of
perpetual motion, but above all, he had the very practical
aim of eliminating the tedious task of rewinding pocket
watches with a key. Around 1770 Abraham-Louis Perrelet
had already developed and fitted several movements with a
so-called "hammer" oscillating weight, using an initial version
of the automatic winding movement called the "mouvement
à secousses" because it was rewound by a jerking motion.
A few years later – and after many resistance-related problems
associated with the shocks sustained by the movement when
the " hammer" weight reaches the end of its travel – he finally
developed an oscillating weight system, fixed onto the central
shaft of the movement, and now usually known as the
"rotor".
