OK, I know you youngsters don't wear watches anymore, because you tell time with your newfangled telephonic devices. And the few who do wear actual watches, wear those digital things, not good old-fashioned analogs.
And you're going to cause the destruction of the Earth!
Look, I will gladly admit that what follow may be just another piece of wonky Silver Age DC Science--hell, the wonkiest.
But what if it is true? What if?
We're reading a tale from the Space Museum, and the exhibit du jour is...
A watch?!?
Well, we're told that Harvey Drake is on Earth's first faster-than-light flight, where he encounters a system whose planets are each near replicas of various epochs in Earth history. Because of Hodgkin's Law of Parallel Planetary Development, or some such.
But on the planet equivalent to the current earth time?
Oops.
So Drake heads back to the "1950s" planet, to see if he can find out what happened:
Red skies in a DC comic? Holy Crisis!
The key is so simple, the Bat-Computer couldn't figure it out!
Wait.
Seriously? The fact that our watches ticked saved Earth from magnetic death-storms?
Yes, seriously.
Let's look at that more closely...
They tied giant watches on the front of jets!!
But that's not all!
And the lesson to be learned?
BY LAW!!!
Get to work, Congress!
And the lesson isn't lost on the youth of the DC future:
Every go and buy analog watches--NOW!!!!!!!
