2010 - at the BASELWORLD, Tag Heuer presented Pendulum Concept, in which the traditional balance spring was replaced by 4 high-performance magnets that produce a permanent magnetic field.
A set of permanent magnets in this construction creates a harmonic vibration system.
The oscillator operates at a frequency of 6 Hertz, and the virtual spring created by the magnets provides linear torque and is more resistant to interference than a traditional balance spring. Despite the use of permanent magnets, we assume that the solution is mechanical.
The name Pendulum is derived from Huygens pendulum clock from 1657.
In 2013, Tag Heuer produced a MikroPendulum watch equipped with an improved Pendulum system, this time for sale.
The modifications came down to eliminating the impact of the temperature change on the accuracy of the watch, which was characteristic of the Pendulum Concept from 3 years ago.
