Swatch out! Chaos erupts over "Royal Pop" watch launch

Chaos erupted over the weekend in Swatch stores around the world as crowds sought to get their hands on a new 'Royal Pop' pocket watch. Police were called to stores across the UK - some of which were temporarily closed - as well as in France and Switzerland, while an event was cancelled in Dubai. The new $450 pocket watch was made in collaboration with luxury watchmaker Audemars Piguet and has been resold online for more than $20,000. CNBC's Ben Boulos and Steve Sedgwick break down the story.
