47. Victorinox ST-5000

Put together by the same industrious Swiss tinkerers who make the army knives, you'd be right to expect some engineering creativity in the Victorinox ST-5000. As if a titanium shell and hardened crystal face didn't make it out-doorsy enough for you, Victorinox's engineers have tacked on a digital compass around the face and a string of LEDs which light up when you're heading in the right direction.

Price: £650
