A watch ahead of its time

TAG Heuer's proprietary spiral hairsprings are designed and produced in its
laboratories in La Chaux-de-Fonds, Switzerland

With its carbon-composite hairspring, TAG Heuer's Carrera Heuer 02T
Nanograph guarantees peerless precision - a ground-breaking clockmaking
development on a COSC-certified chronometer.

Next-generation
hairsprings
Considered as a core component of the mechanical watch,
the hairspring is the most
difficult part to produce,
because its infinitesimal tolerances have a direct, immediate effect on the precision
of the timepiece. A team of
mathematicians, physicists
and chemists working at the
TAG Heuer Institute developed the new hairspring.
The carbon-composite spiral
not only disrupts traditional
watchmaking knowhow, but
also improves the performance of watches equipped
with the brand's chronometer-certified movement. The
Carrera Calibre Heuer 02T
Tourbillon Nanograph model is the first timepiece to be
fitted with the innovative
hairspring. The watch will be
available in April - and not

just as a limited series - for a
price of about 23,000 euros.
A revolutionary hairspring, hexagonal design
The hexagonal structure
of the carbon-composite
material used to make the
hairspring is nanoscopic (a
million times smaller than a

millimetre). This hexagonal
pattern is echoed in the overall design of the Carrera Calibre Heuer 02T Tourbillon
Nanograph and reproduced
on the black PVD-treated
oscillating weight, which
is visible through the sapphire crystal case back. A
bright lime green enhances
some of the watch parts, like
the tourbillon's aluminium
bridge and the lettering on
the cage. The balance wheel
is highlighted with whitegold inserts, while the Super-LumiNova coated markings are perfectly readable,
both day and night.

Forward-looking
Elaborating further on the
importance of this new technology and all the years of
work to improve the performance and precision of
mechanical watches, Guy
Sémon stressed that the series of innovations achieved
in the TAG Heuer Institute
is like a staircase, each new
step leading to the next one.
The spiral hairspring is the
first of many to come.

Focus
Watchmaking terminology
Timepiece - The term originally referred to a high-precision timekeeping instrument that also
served as a reference, providing the exact time anywhere in the world. A timepiece was an instrument such as a marine chronometer or, much later, a crystal-controlled clock or an astronomical
clock. These days, the sense of the term has broadened to include a watch. Many clock-andwatch enthusiasts use the term in reference to a premium watch.

Hairspring - This is one of the most important components of a clock watch movement. A hairspring consists of an extremely fine spring (thinner than a hair) that is coiled into a spiral and
is often made of steel, although more modern watches have a silicon hairspring. This essential
component is one of the most difficult to design, due to its thinness, fragility and length.
COSC - The Contrôle Officiel Suisse des Chronomètres, or the Official Swiss Chronometer Testing
Institute, is a non-profit organization of public interest, and the guarantor for the Swiss precision
clockmaking tradition. It was founded in its current form at La Chaux-de-Fonds in 1973 by five
watchmaking cantons (Berne, Genève, Neuchâtel, Soleure and Vaud) in collaboration with the
Federation of the Swiss Watch Industry (FH). COSC encompasses a number of originally independent testing laboratories, some of which date back to the late nineteenth century.
