The components and bottomplate of the V4 were engineered and machined at the TAG Heuer workshop in La-Chaux-de-Fonds, then assembled and finished by a famous Swiss master watchmaker. The name V4 derives from the movement's four barrels, which are mounted on a V-shaped main plate angled at 15 degrees, like cylinders in a high-end motor racing engine. It also pays tribute to the movement's inspiration: while the V4 draws from the newest concepts in industrial technology, its true muse is the world of high-tech, high-performance racecar engines.
