Spinning the Tech Globe

We take a truly global look at the world of technology this week, with reports from Leo Kelion from Switzerland on how traditional watchmakers are responding to the rise of smart watches, and Jane Wakefield at the TED conference in Vancouver on the next generation of 3D printers. We also hear from Japan's biggest messaging app about censorship in China, and hear about Cuba's first free wifi hotspot from Will Grant in Havana. Presented by Rory Cellan-Jones
