I wear a Casio GShock, don't even remember the model.
Had it for about 5yrs, It's got some roadrash from when I went down, survived Iraq(buddy has the same watch, it's going on 4 tours), being covered in blood, diesel, hydraulic, oil, being bit by a dog (complete with toothmarks), the pacific ocean 2-3x a week, India, and most likely will survive the zombieocaplypse.
Think the diesel got to it though, band is starting to chew a little bit, probably need a new one in 5yrs.
