The new GPW2000-1A Gravitymaster model packages GPS Hybrid Radio-controlled Solar-powered timekeeping into a strong Triple G Resist body. It delivers unmatched accuracy, toughness, and practicality demanded by today's aviators. Virtually unlimited access to current, accurate timekeeping data required by pilots is provided by reception of both GPS satellite information and time calibration signals, as well as Bluetooth® linking. This is the world's first watch* to incorporate three time information acquisition systems. To improve anti-vibration characteristics, the band connects to the watch body without screws. Both ends of the shafts that secure the band are covered with fine resin, and have fine resin stoppers strengthen connections. It also adds an extra level of toughness to withstand severe cockpit conditions. The GPW-2000 Gravitymaster embodies absolute accuracy and unmatched toughness.
