TAG Heuer Pendulum Concept Watch

The 1st Mechanical Movement Without Hairspring

Developed and constructed in-house by TAG HEUER - A MAJOR WATCHMAKING INNOVATION! During its 150 years at the forefront of the Swiss avant-garde, TAG Heuer has written some of the most important chapters in the history of mechanical watchmaking — from the oscillating pinion patented in 1887 to the groundbreaking 1/100th-of-a-second precision of the Calibre 360 chronograph in 2005.

Technological advancements like this point to one underlying truth: TAG Heuer does not innovate for innovation’s sake. The brand’s passion for the avant-garde is an essential element of its DNA and history, and the driving force of its R&D strategy.

TAG HEUER R&D OBJECTIVES IN THE 3RD MILLENNIUM: TO PROGRESSIVELY RE-INVENT THE THREE ELEMENTARY PRINCIPLES OF WATCHMAKING — ENERGY, TRANSMISSION AND REGULATION

Like most machines, a mechanical watch movement involves four basic operations: energy is generated, stored, transmitted and regulated. For centuries, these constants of mechanical watchmaking have been performed by three complementary blocks: a power storage system with cylindrical barrel, a transmission system with pinions and gears, and a regulation system with balance wheel, spiral hairspring and escapement.

With the TAG Heuer Monaco V4 Concept Watch, TAG Heuer substituted the traditional pinion and gear transmission with a belt-driven mechanical transmission. An award-winning BaselWorld concept watch in 2004, the Monaco V4 became a commercial reality at the end of 2009, when it was successfully launched in limited edition of 150 “Haute Horlogerie” pieces.

Now, to mark its 150th anniversary, TAG Heuer proudly introduces the TAG Heuer Pendulum Concept, the first-ever mechanical movement without hairspring.
