Dangerous watch choice!

I've got a drawer full of broken watches at home (some that need a new battery, some with a broken strap etc), so recently bought a cheap and cheerful digital watch.  However apparently my new "Casio F-91W" has potentially marked me up as a terrorist!

Maybe terrorists are on a budget and require a functional, waterproof and reliable time piece; maybe they even have some argos vouchers
