TAG Heuer announces more than 700 Tourbillon movements COSC-certified in 2016 In 2016, TAG Heuer announced that exactly 710 Heuer-02T Tourbillon movements were certified by the independent testing body, Contrôle Officiel Suisse des Chronomètres (COSC). These 710 pieces were produced by the TAG Heuer Manufacture, at its La Chaux-de-Fonds and Chevenez sites in Switzerland. 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 is performed in Switzerland, in-house, at the TAG Heuer Manufacture. The Heuer-02T COSC Chronograph Tourbillon movement was designed and developed entirely at TAG Heuer. This skeleton movement comprises 284 components, within a diameter of 31 mm (13 ¾’’’ [lignes]) and a thickness of 6.9 mm, and beats at a frequency of 4 Hz (28,800 vibrations/hour), boasting a 65-hour power reserve. Its design — deliberately conceived with the strategic aim of falling below the CHF 15,000 mark — was launched in 2015. For this to be possible, 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, this price of CHF 14,900 for a Tourbillon watch is a highly 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.
