With the TAG Heuer Monaco V4 Concept Watch, TAG Heuer substituted the traditional pinion and gear transmission with a belt-driven mechanical transmission. Now, to mark its 150th anniversary, TAG Heuer proudly introduces the TAG Heuer Pendulum Concept, the first-ever mechanical movement without hairspring.

TAG HEUER PENDULUM CONCEPT: A RADICAL “OUT OF THE BOX” RETHINK OF MECHANICAL TIME REGULATION DESIGN AND PERFORMANCE

Since the creation of the Galileo-inspired hairspring by Christiaan Huygens in 1675, the regulating organ of all mechanical watches has been based on a balance wheel and spiral-shaped torsion hairspring system. With the challenge of temperature diminished by Guillaume’s alloys, the spiral hairspring regulation system came to dominate mechanical movement design. In the TAG Heuer Pendulum Concept, the traditional hairspring is replaced by an “invisible” or virtual spring derived from magnets. TAG Heuer Pendulum Concept, the world’s first oscillator in a mechanical movement without hairspring, beats at 43,200/hour (6 Hertz) — making it a superlative representative of TAG Heuer’s unique mastery of high frequencies and ultimate precision.
