Tag Heuer Monaco V4 in Pre-Series Production Tag Heuer informed us at the BaselWorld that the amazing Tag Heuer Monaco V4 is now available in a pre-series of 20 units. Two of them have been worn by Tag Heuer representatives at the BaselWorld 2007.

It is still a long way until the belt-driven timepiece will be available on the market though. The V4 pre-series is currently put through intensive testing to meet Tag Heuer's high quality standards. The aim is also to obtain a COSC chronometer certification for the Monaco V4.

We got several hi-res photos of the Monaco V4 showing the fascinating toothed-belt mechanism in detail in this gallery.

Tag Heuer introduced the Monaco V4 concept watch back in 2004 at the BaselWorld. The company used extensive computer simulations to solve the kinetic complexities the design introduced.

The fundamentals of the V4 are belt drive, ball-bearings, linear oscillating-weight and spring barrels in a V configuration like the cylinders of a sports car.

The functional validation phase of the synchronous belt-drive system and of the automatic winding by linear oscillating-weight is now completed. The next step is to certify the reliability of the complete pre-series prototypes.

Tag Heuer is not able to give a time frame yet, when the Monaco V4 will be available for purchase, but they are getting closer.
