CASIO to Release New G-SHOCK Featuring Analog Chronograph with Iconic Dial Indicator
New G-STEEL Watches with Connected Engine Module

Norderstedt, November, 2017 — CASIO announced today the release of new additions to the G-STEEL series of watches that feature a layer guard structure combining different materials. The GST-B100 and GST-B100D watches feature analog chronographs with a large, distinctive dial indicator, as does the special edition GST-B100X model.

The GST-B100 and GST-B100D are the first watches in the G-STEEL series to feature analog chronographs. An iconic dial indicator at the nine o’clock position is designed in the bold image of the turbine blades on a jet aircraft engine. The dial indicator rotates to graphically indicate the elapsed stopwatch time, alarm on/off setting or battery level. The watches feature a high-power dual coil motor that drives the large dial indicators. The appealing rotation of the dial indicator and the multidimensional watch face make for a chronograph that is distinctively G-SHOCK.

The watches are equipped with the Connected Engine, which connects to Internet time servers via a smartphone, to keep accurate time anywhere in the world. The user can also set the alarms and world time city from a smartphone app. Other practical features including the original high-efficiency CASIO Tough Solar power system, a high-luminosity LED light, and Dual Dial World Time.

The new watches feature an updated layer guard structure that combines metal and resins to absorb shock and is a signature feature of the G-STEEL Series. The shock-resistant resin parts have been incorporated into the case to make for a thinner case. High-density packaging technology has been used to reduce the size of the component modules, further enhancing the wearability of these watches.

The GST-B100X, special edition model, incorporates carbon materials in the bezel. Cutting-edge TORAYCA® carbon fiber and NANOALLOY® resin technology from Toray Industries, Inc. are combined to realize a material with excellent shock resistance and an appealing look that augments the bold bezel design. The face is made from scratch-resistant sapphire crystal with excellent clarity and readability, offering both durability and good looks.

These latest G-SHOCK watches deliver a unique use of materials and a distinctive rotating indicator while offering even greater universal value with their wearability and ability to tell accurate time anywhere in the world.
