I clicked through to the wikipedia entry for the first 10 detainees, in no case is possession of this particular model of Casio watch the only or even primary point of evidence in support of their detention. Some choice bits from various entries for people on this list:
The detainee met with and received money from Usama Bin Laden.
The detainee fought on the front lines for approximately nine months and fired his weapon at coalition forces.
Detainee stated he offered to help the Taliban.
The detainee resided in Taliban safehouses during his travel to and within Afghanistan.
This is certainly a curious thing, but without further info and context I have no basis to make a judgment one way or the other whether possession of this particular model of watch while in Afghanistan/Pakistan is sufficiently unusual to be used as a point of evidence in proving a close affiliation with al qaeda/the taliban. Unfortunately, this wiki page does absolutely nothing to further that investigation, other than to highlight something seemingly odd.
