But...but...I love watches

In these overclocking times, watches are nothing but a giant wad of burned cash hanging on your wrist. They're like a vulgar codpiece of consumption, but, like, on your arm. They are, almost, evil.
They're heavy. They're annoying. They're pretty much duplicative. They're one more thing to sweat under in summer. They leave very awkwardly shaped tan lines. Also, yes, sometimes they're very pretty!

Watches are the Devil's Accoutrement! | The Awl 

But...I love watches.  After shoes, they are the first thing that I notice. Well, maybe glasses.

I have a dozen watches but I wear only one.

It is simple, rugged, and masculine.

So...two questions:  

Are watched necessary?

What do you notice?
