MikeB4: I have a Casio G-Shock that I wear when doing stuff in the garden, cleaning around the home, at the beach and in the pool. They can certainly take a beating.
Both my sons that were in the army had G-Shock muds and the watches survived through basic training, through corpse training and deployments.
