The tourbillons rotate in three dimensions around three axes. This complexity requires intricate calculations for the distance of another orbit to the center point, distribution of overall weight, and the assembly and tuning, making it akin to a fighter jet among tourbillons.
With each additional frame added to the inner three, the complexity multiplies, not to mention the increased energy consumption due to the high speed of rotation.
Eric Coudray, the founder of Jaeger-LeCoultre's Gyrotourbillon I and renowned as the pioneer of multi-axis tourbillons, handcrafts these pieces. He can only produce three a year.
Compared to the standard 60-second tourbillon, the production difficulty and visual impact of Purnell's creation are unparalleled.
The tourbillon frames are made of titanium, ultra-light, ultra-thin, and highly skeletonized (the tourbillon frame thickness is less than 0.2 millimeters. The entire tourbillon weighs less than 0.8 grams, an audacious feat of craftsmanship.
