Abstract The tourbillon was invented in 1795 by Neuchatel born watchmaker Abraham-Louis Breguet in order to negate the effect of gravity on pocket watches while in different vertical positions, as they were worn by men of that time. With the advent of wristwatches in the 20th Century, its usefulness became moot, as wristwatches take on all orientations. Multiple axis tourbillons were invented in order to average all possible orientations of a watch. However, the mechanisms which have been realised all have an intrinsic geometric property which results in a distribution defect. To resolve this means distributing points uniformly on a sphere, a well-known mathematical problem, and a simple method based on a famous theorem of Archimedes was chosen. Its mechanisation was inspired by the Antikythera mechanism of Antiquity. The resulting mechanism can be directly implemented in a multi-axis tourbillon with much improved orientational distribution.
