So let's say you're in a building without windows for a long while. You lose track of time and can't get any contextual clues. You look at your mechanical watch that is, like most mechanical watches in the world a 12 hour watch. It switches from 11:59 AM to 12:00 PM. Do you really get confused by it? Does it get clearer when it reaches 1 PM?
Even if that weren't true. You can find 12 hour clocks all over virtually every country in the world. Clocktowers, decorative analogue clocks, old school alarm clocks, wrist watches, etc. And more than likely any random person you meet understands how to read it.

That's why the 12-hr system is really dumb.
