TAG Heuer Monaco V4 Titanium

The Monaco V4 is an incredible achievement which took the TAG Heuer R&D teams five years of relentless effort to turn into a commercial reality.

The patented belt-driven transmission is a high-yield relay of five notched micro drivebelts whose tension is controlled by two turnbuckles.

A second patent was granted for the innovative linear mass, replacing the classic oscillating mass. Mounted on the world’s smallest ball bearings, the 12g tungsten ingot moves up and down between two pairs of V-shaped barrels (hence the name V4).

The barrels are angled at +/- 13 degrees, like the cylinders of a high-performance racing engine.
