Casio G-Shock Gravitymaster Atomic Triple G Resist GPW-1000-2A Men's WatchDesigned to handle aviation and aeronautical requirements, it is built on Casio’s proprietary GPS HYBRID WAVE CEPTOR system. The small dial elements and button parts are tinted in orange (the emergency colour), while the large black face has everything in white on it. This promotes visibility and that also depends largely on the layout design. Engineered to deliver information without stumbling even a bit - even when flying under severe environments – it’s the G-SHOCK reliability presented in an enhanced format.
