The Link was the first collection to use TAG Heuer’s in-house Calibre S movement, an entirely new type of movement in the watch industry. The Calibre S movement is an electro-mechanical “hybrid” movement, powered by a battery, but with traditional watch and chronograph hands, with 230 components.
In the “watch” mode, the three center-mounted hands display the standard time of hours, minutes and seconds, while the two semi-circular displays at the bottom of the dial – inspired by the instruments of an automotive dashboard – provide a retrograde perpetual calendar (accurate through 2099).
By pressing the crown, the Calibre S movement switches to the “chronograph” mode. The central hands move to zero (the 12 o’clock position) and will now display the chronograph hours, minutes and seconds. The chronograph is started, stopped and reset in the traditional manner, using the pushers at 2 o’clock (start / stop) and 4 o’clock (reset). When the chronograph is stopped, the two semicircular registers at 4:30 and 7:30 will display 1/10th and 1/100th of a second measurements, in retrograde style.
With a push on the crown, the Calibre S movement will switch back to the “watch” mode, though the chronograph may continue in its timing function.
As former CEO Jean-Christophe Babin explained:
“It is more complex than most mechanical movements. You have five engines, all bi-directional. Each engine drives four wheels. You have more wheels in the Calibre S than in a mechanical watch. So even if the heart of the watch is quartz, the Calibre S is much closer to a mechanical product. The assembling of the hands on a bi-directional axis is very delicate, one of the most difficult hand-assembling jobs you’ll find.”
