Split among 3 classifications - updated GW-8900 Series, MTG-1200, and the new "Men in Smoky Grey", the September 2011 product line spells all the available technical advancements from Casio G-Shock. All 8 new designs will include TOUGH SOLAR, an almost indestructible solar cell unit cleverly integrated as part of the dial face. The new additions will also feature Casio's MULTI-BAND 6, automatic time adjustment via atomic clock radio transponders in U.S., Europe, China, and Japan. The system itself is a redundant one, in case of catastrophic failure in one part of the world, like the damages incurred during the March 2011 Tohoku Earthquake and Tsunami in Japan. With the recent and ongoing disasters in different parts of the world, they are also clear indications of the need for a durable timepiece, such as the ones offer by Casio G-Shock.
