This distinction was awarded to a chronometer for the first time in 1897 as a test of metrological quality, which guarantees almost infallible standards of quality and precision. This seal, which fell into disuse, has been reactivated since 2006. Since then, only 500 pieces have been granted this certification.

El TAG Heuer Carrera Chronograph TourbillonIt is an exclusive model limited to 155 pieces launched to commemorate 55 years since the appearance of the Heuer Carrera. The manufacture has worked conscientiously to obtain this exclusive seal of quality reserved only for the best. In fact, the watches awarded the “Tête de Vipère” are subjected, once assembled, to a rigorous testing protocol in various positions and temperature conditions for 16 days. Exceeding them means not only passing the established precision standards, but also almost perfect technical manufacturing, since not only the movement is evaluated but the piece as a whole.

This versionTAG Heuer Carrera Chronograph TourbillonThe 2018 chronometer features two integrated complications, tourbillon and chronograph, with a very modern design. The case that houses its heart is made of midnight blue ceramic, a material that has also been used for the lugs and the bezel. Certain blue details can also be seen on the weight and barrel of the movement. The coveted “Tête de Vipère” seal can be seen on the bridge and through the sapphire crystal on the caseback.

The finishes also show special attention to aesthetics, using refined techniques such as sandblasting or brushing. In addition, its black alligator leather strap sewn on rubber with blue stitching enhances the sporty sobriety of the entire watch, in the line that characterizes TAG Heuer.

In short, the TAG Heuer Carrera Chronograph Tourbillon with the “Tête de Vipère” seal is a perfect example of the know-how and technical mastery of the brand, recognized worldwide for its high level of demand in terms of quality and performance.
