Casio G Shock Watches Tough as hell this is a video courtesy of Deployment testing the GA700. Casio G shock watches have been around a long time the watches are worn by police, firemen etc…. as they are so tough and very practical watch to use. The video demonstrates how tough they really are, I have had them in the past great everyday watch if you not working in a office environment. This watch is not normally something I would post about but they must sell plenty Casio so must be worth a shout out! May be Casio could team up with Rolex for a super tough luxury watch.
