Cammenga J582 Wrist Compass - Black, Phosphorescent

The US Military has been using and issued Cammenga's for decades.  You can trust this compass more than your ability to Land Nav.  

The wrist compass can be worn opposite of you watch, or double up if you want to look like a gypsy, for hands free navigation on the go.  The phosphorescent paint will glow in low light conditions when briefly charged with direct light (use a bright handheld).
