Tourbillion.

Flying Tourbillon Model 1.5 (https://www.thingiverse.com/thing:2751917) by A26, a Thingyverse contributor.

A tourbillon is a mechanical complication found in the movements of certain high-end mechanical watches. It was invented during the era or the pocket watch and is both hypnotic and fascinating to watch. Watches with tourbillons are usually a bit expensive compared to watches without them. They are not the most common complication that you'll find on a watch, but certainly one of the most entertaining.

	All the parts for this were 3D printed apart from small steel rods which were used for axles. The yellow hairspring is 3D printed. I used different colours of filament to show the different parts.
	This is a VIDEO of the tourbillion in action. The white ring and yellow top piece are wound to energise the spring.   CLICK on the thumbnail to play the video in YouTube. CLOSE the YouTube window to return to this page.
