The Casio G-Shock is arguably the best watch to have in the event of a zombie apocalypse. Tough, durable, the very definition of rugged.

They have the best zombie-based commercial available, and it relies on you, using either your mouse on a computer, or your finger on the screen of a tablet, to determine whether an intrepid Brit and his girlfriend will survive, holed up in their post-apocalypse apartment.

You'll want to play again.  First time, though, start out on "tourist" level.

Play it here.  Will you survive Five Minutes?
