Taking its name and inspiration from Steven Lisberger’s 1982 cult film TRON, the HAUTLENCE Vortex Gamma Tron is made with a revolutionary composite material hailing from the automotive and aerospace industry: HLLightColor.

Charged with ceramic nanotube particles, HLLightColor can be body tinted rather than coated with colour. It can also be made phosphorescent, something which immediately appealed to HAUTLENCE, with the brand using it to accentuate the architectural lines of the case and further underline the references to the graphic universe of science-fiction classic TRON.

This highly stylised graphic universe, which employs a range of visual effects, inspired the lines of the Vortex Gamma Tron case, composed of six 3D sapphire crystals.


Playing with the contrasts of colours — white for the case and blue for its edges — and light, with the outlines of its edges glowing in the dark, HAUTLENCE pays tribute to the iconic style of TRON.

The Vortex Gamma Tron undergoes a metamorphosis when the light fades, including the brand’s Möbius symbol which also glows at the centre of the dial, turning on itself with each new hour.


The retrograde minute dial, varnished white and adorned with azure numerals, offers a large window onto the HL2.0 self-winding calibre which drives the HAUTLENCE Vortex Gamma Tron watch. Each of the 12 articulated links in the jumping hour chain features one of 12 white numerals.


The feature at the heart of the movement, the chain turns every 60 minutes, taking 3-4 seconds to move gently, with control, to avoid any shocks or loss of energy, whilst leaving enough time to admire the beauty of the movement and its mechanisms in action. The regulating organ is integrated into the mobile bridge-type calibre, with the change in position actuated by the display improving accuracy by statistically offsetting the effects of gravity.

The calibre HL2.0 has two barrels. The second barrel, dedicated exclusively to driving the complication, is continually reset by the main barrel, so that the optimal level of energy is available each time the hour changes. This double barrel system ensures the complex mechanisms are supplied independently, without affecting the watch’s ability to keep accurate time.

For the Vortex Gamma Tron strap, HAUTLENCE has opted for a high-tech loose-knit fabric, in white with blue top-stitching to match the colour codes of this model.
