If you're truly "surviving," I think a watch is wasted space. It's not like you have a date that's waiting to get picked up.

Besides, one should already be on your wrist. And if you need direction finding abilities, put a compass in instead of a watch.

Instead of a handkerchief, how about a brightly colored bandana? still works for your runny nose, but can be used as a signal flag or trail marker as well.
