TAG Heuer Carrera Calibre Heuer 02T Tourbillon Nanograph

TAG Heuer creates an all-new category of hairspring based on many years of research and development

TAG Heuer is introducing its newest movement, the Calibre Heuer 02T Tourbillon, with a state-of-the-art carbon composite hairspring. Not only has the brand developed the world’s first carbon composite hairspring, but is also already implementing it into a timepiece: the Carrera Calibre Heuer 02T Tourbillon Nanograph.

Case back of the TAG HEUER CARRERA CALIBRE HEUER 02T TOURBILLON NANOGRAPHInvented, designed and manufactured entirely at the brand’s La Chaux-de-Fonds location, the hairspring makes use of a gas production technique that the brand is still keeping under wraps. The hairspring features a microscopic hexagonal pattern that is only one millionth of a millimetre in size. 

The material and the hairspring represent the latest evolution in specialised synthetic and silicon hairsprings and boast a host of benefits that have been tested by TAG Heuer. Among them are the lighter weight and lower density of the hairspring, anti-magnetic properties as well as the resistance to gravity and shock. The geometry of the composite, say TAG Heuer’s team, offers improved efficiency. 

The hairspring graces the new automatic Calibre Heuer 02T Tourbillon chronograph that beats at 4 Hz and offers 65 hours of power reserve. It meets chronometer standards and is certified as such. 

The movement (and, hence, the hairspring) is being utilised for the first time in the new 45 mm Carrera Calibre Heuer 02T Tourbillon Nanograph, whose case and dial reflect the hexagonal patterning of the hairspring.


The Carrera Calibre Heuer 02T Tourbillon Nanograph features a multi-layer skeletonised dial with sandblasted hexagons on the movement plate that are visible via the open-worked dial. The same pattern is replicated on the rotor using a black PVD treatment. The case of the watch is created in black PVD titanium with a carbon bezel featuring a tachymeter scale for a harmonious appeal. 

To underscore the high-tech/high-mech look of the sporty watch, TAG Heuer turns to a neon green accent colour for the aluminium bridge of the tourbillon escapement. Super-LumiNova for the hands and markers also brighten up the look. Fitted with an anti-reflective sapphire crystal, the watch is water-resistant to 100 metres and finished with a calfskin leather and rubber strap.

TAG Heuer has been making a host of strides in developing its own calibres and in the use of new materials and watch concepts, as it focuses squarely on the future. The development of the carbon hairspring, which the brand makes in house, is indicative of TAG Heuer’s commitment to watchmaking excellence.
