I like it... but not enough to replace my original Khaki Field Auto...

So the screw down crown on an Explorer or Ranger is just unnecessary?

Kinda, yeah.

I mean, nothing wrong with having it. It's just an added layer of security. But it's not a real necessity, unless you're in the water a lot and are clumsy.

I take my Khaki Field swimming and it does just fine.

Doesn't this have the disposable Powermatic 80 movement with the plastic escapement?

It's the caliber H-10 with silicone mainspring. What's your point? Aren't most movements inherently disposable and replaceable?

Not quite.

The H-10 (ETA C07.611) has a standard jeweled escapement and a standard metal mainspring.

Nobody uses silicon for the mainspring. There are some movements with silicon balance springs, including a version of the Powermatic 80, but the H-10 doesn't have one. Current versions use Nivachron for the balance spring which is antimagnetic, but still a metal alloy.

And none of them are disposable. They are all fully serviceable, including the "plastic escapement" version.
