TAG Heuer Monaco V4 Concept Watch

TAG Heuer Monaco V4 uses ball bearings and is belt-driven – a totally new type of watch movement. The Monaco V4 is the first mechanical watch movement to replace traditional pinions with driving belts. The pinions of the traditional mechanical movement have been replaced with a relay of five driving belts whose tension is controlled by turnbuckles - replica tag heuer monaco.

A unique linear automatic winding system is used to reload energy. The oscillating weight which generally supplies the energy for an automatic watch has been replaced by a linear oscillating weight. In the Monaco V4 this is a 12g tungsten ingot that moves up and down on a track between the four spring barrels. The system of teeth on the long side of the weight engages a toothed wheel and translates the linear movement into a rotating movement.

The movement’s energy is provided by four barrels in 2-by-2 series and linked to a differential with a V-shaped bridge. Each barrel delivers 4 N.mm of energy. The barrels are mounted in a V-shape (at 15° in respect to the dial). The barrels are held directly onto the bottom plate, allowing the movement to be visible from below. It is this unique design component that gives the Monaco V4 its automobile-sounding name.
