Casio just announced the all-new G-Shock G-STEEL GST-B100 featuring Tough Solar power and Bluetooth connectivity. Like the other G-STEEL models, the GST-B100 has a layered guard structure for superior shock resistance but is 2 millimeters slimmer than the original GST-S100. The launch models include the GST-B100-1A with resin band, the GST-B100D-1A with stainless steel band, and the special edition GST-B100X-1A with a carbon fiber bezel and resin band.
The GST-B100 is the first fully analog G-STEEL model and has a subdial for dual dial world time. Another distinguishing feature is the unique dial indicator at the nine o’clock position which resembles the turbine blades of a jet engine. This dial rotates to graphically indicate elapsed stopwatch time, alarm setting, or battery level. The Connected Engine Module supports a Bluetooth connection to a smartphone to automatically adjust the time with internet servers, or to use a smartphone app to adjust the alarm and world time settings. The GST-B100 measures 58.1 x 53.8 x 14.1 mm, which is similar to the original GST-S100 (59.1 x 52.4 x 16.1) but significantly slimmer. The slimmer size is the result of the shock-resistant resin layer being incorporated into the case.
The special edition GST-B100X-1A combines Torayca carbon fiber and Nanoalloy resin technology for a striking bezel design and also has a sapphire crystal.
This exciting new release for G-Shock is another affirmation of the brand’s dedication to technological innovation. This is the third G-Shock watch featuring Tough Solar and Bluetooth connectivity (behind the GPW-2000 Gravitymaster) and MRG-G2000), and it looks like the Connected Engine Module may become a more common feature in future models.
