Have mechanical clocks' time passed?

In an age of multifunctional phones, wristwatches are evolving to do more than tell the time – they now come equipped with a music player or even a personal locator beacon.

BBC Click’s Marc Cieslak discovers how far time has come since the clock tower containing Big Ben was built, and looks at devices that do more than just tell the time – incorporating personal locator beacons, phones and music players.
