The G-Shock 35th Anniversary Gold Tornado Collection includes three high-end models and features a black and gold design with red inner band layers. A gold ion plating is applied to the metallic parts to celebrate the April 2018 anniversary while the black and red pay tribute to the classic G-Shock color scheme. Like the first 35th anniversary series, the Big Bang Black Collection, the strap keeper and engraved case back feature special 35th Anniversary graphics designed by Eric Haze, and a commemorative “Since 1983” red text adorns the face. The Gold Tornado models include the GPW-2000TFB-1A Gravitymaster, G-STEEL GST-B100TFB-1A, and GWF-D1035B-1 Frogman.
This model features a carbon fiber bezel. Base model is the GST-B100, a recently introduced Bluetooth-connected full analog model. Standout features include Tough Solar, Bluetooth time-sync, and dual dial world time. The dial at 9 o’clock has a multi-functional rotating disk that is cut to resemble the thick blades of a jet engine. Rotation of the blades reveals red coloring behind the disk, and this change in color is used to indicate the battery level and the alarm on/off setting. The blades also rotate in the Timekeeping and Stopwatch modes to with the passage of time.
A new layer guard structure houses resin cushioning parts inside the case, for a more elegant design and a better fit to the wrist. High density mounting technology makes it possible to create a module that is smaller and thinner, which also contributes to a better fit. These watches are equipped with Bluetooth® that lets them connect with a smartphone at the press of a button, and acquire time information from an internet time server. The result is accurate timekeeping no matter where in the world you happen to be. Other functions include Tough Solar in combination with CASIO original power saving technology for a stable supply of power, high brightness LED light illumination, and dual dial World Time.
