X-TREM-1 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 tubes on the left and right sides of the caseband, magically move with no mechanical connection thanks to magnetic fields.
Driven as ever by a determination to present avant-garde timepieces, 5N red gold and black grade 5 PVD titanium were the metals chosen to make the case of this version of the X-TREM-1. The sapphire tubes have been replaced by cylindrical ring-bound tubes housing mobile stainless steel spheres indicating the time.
This version is produced in an 8-piece limited edition.
