Casio G-Shock Gravitymaster GPS Hybrid Radio-controlled Solar-powered Black Resin Strap Watch GPW2000-1A2 GPW-2000-1A2

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 the 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 GPW-2000 GRAVITYMASTER embodies the ultimate in absolute accuracy and unmatched toughness.
*As of March 2017. CASIO research.

3-way Time Sync
Bluetooth®-equipped GPS Hybrid Wave Ceptor
Accurate timekeeping is assured by the installation of three advanced time-correction systems: terrestrial radio wave reception (Multi Band 6), GPS satellite signal reception and Bluetooth® transmission. The most appropriate system is selected automatically depending on the conditions, and the correct time is displayed for the current time zone anywhere in the world.
