Mr. Kikuo Ibe never expected to be world famous, but famous he is: he's the man who invented the Casio G-Shock. At first, he hardly seems like the sort of person who could develop the world's toughest watch. He's slightly built, slim, soft-spoken, and bespectacled, which seems a little incongruous until you remember that G-Shock is as much an engineering achievement as a horological one, and Mr. Ibe is very much an engineer.

The history of the G-Shock is full of interesting stories (as you'd expect of a family of watches designed to tolerate just about any sort of abuse imaginable) and in a recent conversation with Ibe, at Casio's offices in New York, I had a chance to dig back a bit into those stories and to find out what's apocryphal, what's legend, and what's true. Many of the highlights in the story of G-Shock are familiar to hardcore G-Shock fans (and yes, there is a worldwide community of G-Shock collectors as serious about their watches as any gaggle of vintage Patek or Rolex collectors), but hearing them from the man who started it all over 30 years ago is a reminder of how much persistence it took to bring G-Shock to life.
