Casio is adding four new G-Shock G-STEEL watches for Japan and Asia in March 2019. Japan is getting the black and gold GST-W300GL-1AJF and silver GST-W330L-1AJF with Tough Solar/Multi-Band 6 and other Asian markets are getting the GST-S300GL-1A and GST-S330L-1A with Tough Solar and without Multi-Band 6.
The Multi-Band 6 feature allows the watch to automatically sync the time via radio waves if it is within range of one of the six transmitters. In cases like this with similar “W” (solar and radio) and “S” (just solar) releases, the “W” models are often released in China and Europe along with Japan.
The GST-W300GL-1AJF and GST-S300GL-1A have a black Tough Leather band and the GST-W330L-1AJF and GST-S330L-1A have a brown Tough Leather band. The Tough Leather band is made of synthetic leather and a resin core and is resistant to impact and water.
The GST-W330L-1AJF and GST-S330L-1A are equipped with a full auto dual LED with the Neon Illuminator black light LED for the hands and markers and the Super Illuminator LED for the LCD displays. The GST-W300GL-1AJF and GST-S300GL-1A are equipped with a full auto dual Super Illuminator LED light. (Casio-intl.com lists the Neon Illuminator as a feature of the GST-S300GL-1A but we believe this is a mistake.)
The GST-W330L-1AJF and GST-S330L-1A are also available in larger versions as the GST-W130L-1AJF and GSTS130L-1A.
