The new HYT Conical Tourbillon is ceated by master watchmaker Eric Coudray, who took inspiration from the unique inclined balance tourbillon developed by Walter Prendel in 1928, it provides a new solution to improve the stability and performance of the tourbillon.

Its dual movement effect created by the retrograde fluid hour markers and the turning of the conical tourbillon with its dynamic movements. This suspended tourbillon movement with a spring-balance is inclined at 30 degrees to horizontal, the escape wheel at 15 degrees, and a pallet at 23 degrees.

At the very heart of the dial, where the conical tourbillon completes a clockwise revolution in 30 seconds, there are three spheres rotating at different speeds which are easy to observe: the first completes four turns a minute, the second five turns a minute, and the third six turns a minute, clockwise.

These spheres are also filled with fluorescent liquid so that their rotations can be seen. In order to contain this glow-in-the-dark liquid.
