The Breitling Watch Source Forums

The most well known belt driven watch is the Tag Heuer Monaco V4, but that's slightly different - it doesn't use the belts to display the time. This link is for the concept, but it is now available for around $80,000 - http://www.europastar.com/magazine/cove ... y-tag.html

The more typical look is probably most famously in the Harry Winston Opus 9 - http://watchismo.blogspot.com/2009/03/o ... world.html which comes in at $180,000.
