Some men were apparently kept at Guantanamo just for owning one of the world's most common watches. To quote the BBC:
The [Casio] F-91W [watch] instantly proved popular, not least because it was cheap and reliable. The company does not release sales figures for the watch, but says it was - and still is - a "huge seller" all over the world.
"It sells globally, from Russia to Asia," says Tim Gould, head of marketing at Casio UK. "It has consistently remained popular because it is functional, affordable and accurate. It's as simple as that."
