Since the Sixties, TAG Heuer’s chronographs have been synonymous with the world of motorsport, but never as viscerally as this year’s Carrera Calibre Heuer 02T Tourbillon: the watchmaker’s own high-octane ‘engine’, turbocharged with a whirring tourbillon carriage, has been tuned up with F1’s favourite lightweight material.


The dial’s openworked hexagon motif is for good reason: it’s the molecular arrangement of pure carbon atoms, in both of the crystalline forms that make up the balance spring’s composite. Namely, cylindrical ‘nanotubes’ and their unrolled, sheet-form ‘graphene’ allotrope.

Just when you thought pure carbon was restricted to the superstructural aspects of a watch – cases, baseplates, bezels, dials – TAG Heuer is proving its mettle for tricksy mechanical components. In this debut case, the tricksiest of all: the spiral balance spring, on which the balance wheel oscillates as the watch’s ticking ‘pendulum’.


As if a carbon balance spring wasn’t impressive enough, it ticks at the heart of a whirring ‘tourbillon’ carriage – a 218-year-old invention that rotates the entire balance assembly by 360º per minute to even-out the ‘squashing’ effect of gravity.

Like silicon (and unlike traditional metal alloys), carbon springs give you antimagnetism, perfectly concentric oscillation and come with the ‘collet’ axis attachment integrated into the mono-structure. But it’s the 5,000g shock resistance of crystalline carbon that’s the main draw over silicon – still avoided by purist watchmakers for its brittleness.

Like silicon parts, TAG Heuer’s carbon hairsprings are made with a photolithography process, but one that grows the parts on a silicon wafer, rather than etching them from one. A complex series of chemical and gaseous baths and reactions grow the composite at a molecular level to give it outstanding flex characteristics.
