TAG Heuer Monaco V4.
The Monaco V4 concept watch was the first ever “belt driven” movement – and is still the only such movement to operate in the way it does. It is gimmicky sure, but it looks very cool, and still images don’t really do it justice. Another unique aspect of the watch it’s the automatic winding system. Instead of having a rotor that oscillates, it has a weight that moves in a linear fashion up and down – just like a piston almost. That movement acts to move gears that wind the mainspring. I don’t know exactly how elegant it looks in reality, but it is certainly a very interesting concept, and now reality.
