Being the good citizen I am, I wear a citizen watch...hell, it tells time (analog) and has a digital window which shows UTC and a few other time zone local times, but generally just the basic bits for me.
The USN were really big on G-SHOCK watches when I was there...really gi-normous...was I compensating for a deficiency? Not sure, but if I'd ever been in a high G impact, my bloody arm would've been ripped off due to the sheer mass of the darned thing.
Geez I feel better being out of the G-SHOCK closet.
