Tourbillon is a very intricate mechanism that counteracts the influence of gravity on mechanical watches and thus makes it more efficient. Invented by Abraham-Louis Breguet in 1795, it is a three-dimensional rotating cage that houses the escapement and balance wheel. This constant motion equalizes the effects of gravity on the movement of the watch to ensure a more consistent time-keeping. Modern technology has reduced the need for tourbillons in the common watches of today but, rather, remains as a symbol of horological excellence and craftsmanship.
A tourbillon timepiece is considered an engineering marvel as it demonstrates the watchmaker's craftsmanship to make fine, precise instruments. Its rotating movement also gives a breathtaking visual appeal to the watch.
