Casio G-Shock GW-9400: the Rangeman. Perfect companion for the end of the world (or just your weekly trek to Costco). Has a solar panel built into the face, so you never have to worry about this beast dying on you (unless you get lost in a cave for months on end). Watch is water resistant to 200m (for when you encounter water in that cave you just got lost in). Has a built in altimeter, compass, barometer, and thermometer (barometer has been the most useful in my experience - kept me dry when the weather turned)./ Can withstand almost anything you can throw at it! Please it is easy to read no matter the situation. (There are some light scuffs on the raised bezel)
