Louis Moinet Mobilis

The function of the double tourbillon is to animate a kaleidoscope which offers the magic of an optical illusion.

Mobilis is the first and only Double Tourbillon whose function is to power a watch complication – the first patent application of its kind.

To achieve this, two huge tourbillon cages measuring 14.9 mm in diameter have had to be designed. What’s more, one has to rotate clockwise and the other, counter-clockwise (second patent application). And most importantly of all, they’ve had to be crafted from cutting-edge materials, so that they can be as light as possible (0.4 gr per cage) whilst still providing the force required to bring the watch complication to life.

The magic of the optical illusion is based on the kaleidoscope complication at 12 o’clock. Its architecture is composed of two cut-out discs - one atop the other - driven by an inverted gear system.


Suspended in mid-air, the tourbillons drive the kaleidoscope with its two discs made of titanium, a material whose extreme lightness is crucial in enabling a 60-second rotation of the discs.

The movement is housed in an avant-garde case featuring an all-new, intricate design. The two side shafts are crafted from blocks of solid gold, sculpted and embellished with black zircons.
