This fully patented timepiece, which was created in-house at TAG Heuer’s La Chaux-de-Fonds workshop, uses a micro-belt to drive the tourbillon. It is equipped with an automatic linear rewinding system, and the mass is guided by a linear railroad instead of a traditional rotating system. The four notched micro-thin transmission belts (the design of which have been kept secret) create an efficient shock-absorbing system. In another first, the barrels are held and rotated on ball bearings. The 214-component movement boasts a 40-hour power reserve.
Housed in a 41mm x 41mm case of space-grade black titanium, this timepiece features an openworked dial with hours and minutes, as well as small seconds on the second wheel at 6 o’clock. The belt-driven tourbillon is visible at 9 o’clock, while an engraving of the TAG heuer logo is visible at 5 o’clock and a “V4” engraving is visible at 7 o’clock.
