How about a dive watch? Strap it to something heavy enough to stay

How about just a plain old waterproof watch?

Also an ordinart $3.50 wall clock from Walmart encased in a clear
plastic bag would work.

But not the kind that need to be plugged into an outlet....

Why not? I've got an old, two-prong, wall clock that should work...

I'm thinking we need to run this past the Legal Dept. pretty soon, I see
lawsuits on the horizon.
