This item in the Guardian's coverage of the latest Wikileaks dump is not the first time I've heard that the Casio F-91W digital watch is thought to be "the sign of al-Qaida," and "a contributing factor to continued detention of prisoners by the analysts stationed at Guantánamo Bay."
But like so much revealed by Wikileaks, when stuff like this is proven out in the State Department's own pen, the absurdity levels really spike:
Briefing documents used to train staff in assessing the threat level of new detainees advise that possession of the F-91W – available online for as little as £4 – suggests the wearer has been trained in bomb making by al-Qaida in Afghanistan.
The report states: "The Casio was known to be given to the students at al-Qaida bomb-making training courses in Afghanistan at which the students received instruction in the preparation of timing devices using the watch.
Next: a global movement to show solidarity with detainees by wearing the F-91W?
