Solar flares

While the magnetic fields in X-TREM-1 are precisely controlled to avoid affecting the movement, solar flares in the Sun’s corona are chaotic. They are caused by sudden changes of very strong magnetic fields in the Sun’s corona and shoot many 1,000s of kilometers from the sun’s surface.

Butterfly nebula

The same magnetic force responsible for moving the X-TREM-1’s indications is also now thought to be responsible for some of the largest and most beautiful objects in the universe: planetary nebulae. The magnetic fields created in stellar evolution can survive for billions of years.

  1. Inspiration

  2. Inspiration



X-TREM-1, the first of a new generation of timepieces, represents a major technical and aesthetic accomplishment: a flying tourbillon inclined at a 30° angle, mounted on a three-dimensional curvex titanium mainplate, equipped with a retrograde hours and minutes display system that is radically different from existing watchmaking conventions. Two tiny hollowed steel spheres, isolated within sapphire tubes on the left and right sides of the caseband magically move with no mechanical connection thanks to magnetic fields.
