Way to Spot al-Qaeda Terrorist: Casio Watch

If you wear a cheap Casio watch around Afghanistan, watch out: The US military might just mistake you for a terrorist. According to the newly leaked Guantanamo documents, the ubiquitous timepiece was considered “the sign of al-Qaeda,” and used to help justify the detention of several prisoners, the Guardian reveals. The Casio F-91W and the silver-colored A-159W model were "known to be given to the students at al-Qaeda bomb-making training courses in Afghanistan,” a report explains.

The students were allegedly taught to time their explosive devices using the watch. “Approximately one-third of the JTF-GTMO detainees that were captured with these models of watches have known connections to explosives,” the report continues. More than 50 detainee files contain mentions of Casio watches, and the Los Angeles Times notes that 9/11 mastermind Khalid Sheikh Mohammed was wearing one when he was captured in March 2003.
