This new 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 shafts that secure the band are covered with fine resin, and fine resin stoppers strengthen connections. It also adds an extra level of toughness to withstand severe cockpit conditions. The GPW2000 GRAVITYMASTER embodies the ultimate in absolute accuracy and umatched tougness.

Triple G Resist
Designed to withstand the shock of three forces: gravitational dropping forcess, centrifugal gravitational force and vibration.
Magnetic Resistant (ISO 764 standard-compliant)
A magnetic-resistant plate installed in the module prevents stoppage or shifting of the hands due to magnetic forces.
Dual disk displays
A second disk capable of displaying various functions such as the current mode and day of the week is installed in addition to the date display disk.
Latitude / longitude display
When GPS satelite signals are received, the curent location's latitude is displayed on an inset dial at 9 o'clock and the longitude in a window at 6 o'clock. The latitudes and longitudesof selected cities are also displayed when switching among Wolrd Time cities.
Flight Log function (Smartphone App)
Time point memories are input by button operation (time stamp). Location information is obtained by simultaneous connection to the smartphone and the point is marked on the map. The Flight Log is useful for reviewing travel history, including the point of departure, interim and final destinations, and return destinations.
Shock-resistant, carbon fiber-reinforced resin band structure
Fine resin parts (FRP) are installed at both ends of the band shaft and fixed with carbon FRP stoppers, strengthening the connections between case and band. The introduction of a fiber insert resin band.
A high-transparency, abrasion-resistant sapphire crystal with a non-reflective coating is installed to ensure clear visibility.
