2010 Tag Heuer : a chronology Pendulum

TAG HEUER PENDULUM CONCEPT: A POTENT NEW TECHNICAL MILESTONE IN MECHANICAL MOVEMENTS   The TAG Heuer Pendulum Concept is the first-ever magnetic oscillator without hairspring capable of providing a restoring torque comparable to that of a hairspring: the basic principle of the Swiss anchor escapement is therefore unchanged, but the absence of mass and therefore inertia allows for much larger frequencies. Theoretical precision is significantly higher as it is possible to oscillate at small angles (the elementary principle of oscillator accuracy) without altering the return torque and, especially important, without causing geometric deformations.
