TAG Heuer - More than 700 tourbillon movements COSC certified

TAG Heuer More than 700 tourbillon movements COSC certified

TAG Heuer had 710 Heuer-02T tourbillon movements certified by the independent testing body Contrôle Officiel Suisse des Chronomètres (COSC) in 2016.

The 710 certified pieces were produced by Tag Heuer in Switzerland, at its La Chaux-de-Fonds and Chevenez sites. From machining to fitting of the main plate, assembly of the movement, adjustment and fine-tuning, casing-up, functional and aesthetic testing, engraving and fitting of the bracelet or strap: every step was performed in Switzerland, in-house, at the TAG Heuer Manufacture.

The Heuer-02T COSC Chronograph Tourbillon movement was designed and developed entirely at the Manufacture. This skeleton movement comprises 284 components, within a diameter of 31 mm and a thickness of 6.9 mm, and beats at a frequency of 28,800 vibrations/hour, boasting a 65-hour power reserve.

More than 700 Tourbillon movements COSC-certified

Deliberately conceived with the strategic aim of falling below the CHF 15,000 mark, its design was launched in 2015. Every team within the Manufacture (engineers, watchmakers, designers, purchasing, production) was involved in the process to enable costs to be optimised at each stage.

Thanks to this synergy, the challenge was successfully met, and the finished piece was unveiled at BaselWorld 2016. In the Swiss watchmaking industry, the price of CHF 14,900 for a Tourbillon watch is a very competitive one. It is in line with Jean-Claude Biver's desire and the strategy he put in place to make TAG Heuer the leader in accessible luxury.
