Tag Heuer loves suspense, as we all know from its first hint to its final deliverance, in 2009, of the Tag Heuer Monaco V4. Now Tag Heuer has unveiled a pendulum watch which has completely redefined the traditional mechanical movement of a watch. With this new concept watch, an important factor is not what is added, but what is omitted. Watch this video for greater clarity.
This watch has no hairspring. The hairspring is a fine coiled spring that regulates the movement of the balance wheel, and is quite sensitive to change in temperature. In place of the hairspring, Tag Heuer has implemented a pendulum “spring” regulated by magnets and beating at a frequency of 43,200/hour (6 Hertz). The pendulum is by no means a new idea, as the pendulum clock was invented by Christiaan Huygens in 1657, one of the first great horologists. It was a marine timekeeper which used a pendulum; however the great rolling waves confounded its accuracy and changes in temperature and humidity thickened its oils. Huygens, then patented the spiral balance spring as alternative to the pendulum. You could say Tag Heuer has returned to its watch making roots with the reintroduction of the pendulum as part of the watch movement.
I am truly excited by Tag Heuer's historic new endeavor as it has the potential to make great waves in the world of horology.
