^ Owned a few in the past (Core All Black & Core Steel Steel). A glass protector is highly recommended if you intend to do physical activities with it as the glass scratches easy. It also goes through batteries rather fast if you're using any of the ABC functions frequently.
I'd recommend taking a look at the Casio Tough Solar Pathfinder / Pro Trek line if you're in the market for that type of watch as I find those are more rugged
PS: if you're buying it because you saw Denzel wearing one in the Equilizer to time his ass kicking's with a large stop watch counter, its does not function like that on the actual watch
