Casio Computer Co., Ltd. launched the newest additions to its series of shock-resistant G-SHOCK watches designed to celebrate the 40th anniversary of the G-SHOCK brand and its never-ending pursuit of toughness. The six Adventurer’s Stone models are inspired by stones that adventurers have long used to navigate.
Since the launch of the very first G-SHOCK, the DW-5000C, the brand has continually evolved not only in shock resistance but in functionality and exterior design, as well.
The 40th-anniversary Adventurer’s Stone shock-resistant models are inspired by the stones known to adventurers as useful compasses since the Middle Ages. The G-SHOCK brand concept of continuous innovation inspires people to take on new challenges, and the design of this line is based on the value that these stones have always had to people seeking adventure.
The watches’ metal bezels are forged and textured to reproduce the rough feel of stone. The textured surface is also honed, while the top and sides are treated with hairline and mirror finishes, bringing out a crystalline beauty. Each inspired by a different type of stone, the bezel is treated with one of many different colorful ion platings to reproduce the look of that particular mineral and the unique way it shines depending on the light and cross-section of the stone. Each model’s band is designed to complement the bezel.
As befits an anniversary model, the anniversary logo is engraved on the case back, there are four stars for 40 on the band loop, and the phrase “SINCE 1983” appears on the dial.

Six Adventurer’s Stone Models
GM-5640GEM
This model begins with the GM-5600, and its original G-SHOCK form, and incorporates a design inspired by sunstone, a stone associated with “bringing about victory.” The entire bezel is treated with rainbow-color ion plating, then sparsely masked and ion-plated in black to reproduce the sunstone’s multicolor shine, which changes depending on the viewing angle.

Based on the GM-110 with its distinctive dimensional dial, the GM-114GEM is inspired by calcite. This stone is found in various hues and is said to “lead onward to success.” After an initial overall ion plating in gold color, the sides are masked at 5 and 10 o’clock and the bezel is ion-plated in black to achieve a two-tone look. To complement the calcite motif, this model features a black band in textured resin.

GM-2140GEM
The octagonal bezel and simple design of the popular GM-2100 take on the look of cordierite, the stone associated with “showing the way.” Beautiful cordierite blue is reproduced with a blue ion-plated metal bezel and band made with the Garal molding technique that mixes two different colors of resin.
