A new G-Shock GWG-100 Mudmaster line has been revealed and it is already available in China as a December 2017 release. Models include the black GWG-100-1A, olive green GWG-100-1A3, and gray GWG-100-1A8. Like it’s big brother the GWG-1000 and unlike the GG-1000, the GWG-100 is equipped with Tough Solar power and Multi-Band 6 radio timekeeping. Unlike those other two Mudmaster lines the GWG-100 does not have any environmental sensors. Features include shock resistance, 200-meter water resistance, mud and dust resistance, world time, 1/100 second stopwatch, countdown timer, alarm, and auto Neon Illuminator light. All three models have silver buckles and resin strap keepers. The dimensions are currently unknown but probably similar to the GG-1000. The list price is ￥2,090 CNY each (~$321 USD).
The GWG-100 Mudmaster looks to be a good option for those who want the tough look and ruggedness of the GWG-1000 but in a smaller and more affordable version, and prefer a solar and radio-powered model over the GG-1000 Mudmaster with Twin Sensor. A distinguishing feature of the GWG-100 to keep in mind is the Neon Illuminator versus the double LED light of the GWG-1000 and the Super Illuminator of the GG-1000. The Neon Illuminator is essentially a “black light” LED that illuminates the analog hands and markings very clearly in the dark but will not light up the digital LCD display. The double LED light of the GWG-1000 does illuminate the LCD display and the Super Illuminator of the GG-1000 mainly illuminates the analog hands and markers and not the LCD display like the Neon Illuminator.
