All the aviation Gravitymaster models are large-size watches with analog displays and feature shock resistance and 200 meter water resistance. All the Tough Solar/Multi-Band 6 models feature full analog multi-dial displays with Neo-Brite luminous hands, and Triple G Resistance to shock from dropping force, centrifugal gravity (g-force), and heavy vibration. Note that models with the Neo-Brite luminous hands do not have a viewing light with the exception of the GPW-1000, though the luminous hands will glow in the dark.

G-Shock GW-A1100 Aviation Watch

Main Features: Tough Solar, Multi-Band 6, Triple G Resist, Compass, Smart Access, Sapphire Crystal
Other Features: Neo-brite Luminous Hands and Markers, Tough Movement, world time, beeper alarm, 1/20 second chronograph, countdown timer, full auto-calendar day/date display, 12/24 hour formats
List Price: $650

Notes: The GW-A1100 has a sapphire crystal which is only available on a few high-end G-Shock models. We like the looks of the GW-A1000 but prefer the compass sensor of the GW-A1100 over the thermometer. The “Fly-Back” button seen in the photo allows the chronograph to be instantly reset and restarted. The GW-A1100 would be a good all-around choice for any pilot.

Notes: The GPW-1000 was the first G-Shock watch with GPS Hybrid Wave Ceptor technology. This allows the watch to synchronize the time with GPS satellite signals if outside the range of Multi-Band 6 radio signals. It also allows the watch to adjust the time zone and DST automatically. As one of only two G-Shock models with this feature it is one of the most innovative aviation watches available. The GPW-1000 is a good choice for a pilot who is constantly crossing time zones. Its features also make it useful beyond aviation and into the realm of extreme travel and adventuring. It is also available in a lighter titanium version.
