If you’re traveling overland, every thing you carry is Weight. Proper noun.
So, your every possession must be useful. And robust. And light.
A good wristwatch is all three of those. Which raises the question, “what is the best watch, ever?”
I submit to you: the Casio F-91W
So useful that, simply being caught in Afghanistan with one is enough to implicate you as an enemy combatant.
So robust that, contrary to la Wik, the “Water Resist” is showerproof.
So light that, if you hold down the appropriate button, you can toggle through multiple backlight colour options. The last one being the best— your future timepiece will flash red, green and blue throwing a miniature rave.
I like to think that when terrorist car-bombs go off, they’re detonated by F-91Ws in Party Mode.
