The G-Shock Australia website revealed the GAS-100, an all-new Tough Solar analog-digital model listed as “coming soon.” We thought this model (or possibly a GAW-100 with Multi-Band 6) might be a July release in Japan, but it looks like it will be August at the earliest. The G-Shock GAS-100 will launch in three styles, the GAS-100-1A (left), GAS-100B-1A (middle), and GAS-100G-1A (right).
The GAS-100 has the same analog-digital display layout and likely the same module as the G-STEEL GST-S100 series, but with a stainless steel bezel and resin case design that is reminiscent of the smaller AWG-M100. No dimensions are available yet but it is described as a “big case” model so it is probably similar in size to the GST-S100. (Update: The GA-100 is using the same bezel as the GA-200 and measures 55.1 x 52.5 x 16.7 mm.)
Features include shock resistance, 200-meter water resistance, Tough Solar power, hand shift feature, full auto double LED light with afterglow, 48-city world time with UTC and DST, 1/100 second stopwatch, countdown timer (100 minutes), 5 daily alarms, battery level indicator, and 12/24 hour format.
Update: G-Shock Japan announced the GAW-100-1AJF (Â¥25,000 JPY), GAW-100B-1AJF (Â¥25,000 JPY), and GAW-100G-1AJF (Â¥26,000 JPY) for an August 2017 release. These models have Multi-Band 6 radio wave time syncing which the GAS models do not.
