Improvised explosive devices can be designed cleverly to resemble common items such as smart phones or wrist watches, or even the sole of a shoe. The triggers for these devices can sometimes be very elaborate. I believe that the TSA has every right to investigate suspicious devices, and a watch with fuses and wires protruding from it warrants further inspection.

A true explosive device trigger is likely to have wires on it . Explosive devices will also have resistors and perhaps a fuse (can't see why exactly) but to an average TSA employee any device which looks out of the norm with wires is immediately suspicious.

And honestly, if you're going to go to the airport, don't be an idiot. Everyone knows the TSA is hypersensitive and quite ignorant of engineering concepts or art in this case, don't push the limits when you know that this is likely to happen.
