TAG Heuer launched a limited series of 150 pieces with the Monaco V4 model. It is so far the only known watch made by TAG Heuer in platinum.
Interestingly, TAG Heuer designed a liner weight automatic movement, shifting up and down to power up the movement and resembling an engine piston. Four barrels store the liner weight power and are displayed at the rear of this V4 Monaco edition. Also, instead of the commonly used rubies, the present watch uses so-called ball bearings to provide even less friction.
The present TAG Heuer is furthermore in overall excellent condition and is number 1 from this limited edtion of 150 pieces.
