Casio wristwatch G-Shock first generation reissue model made biomass plastic DW-5000R-1AJF mens black.

The "First Generation G-SHOCK Reissue Model," symbolizing the evolution and inheritance of the brand, merges the original design with modern technology after over 40 years. On April 12, 1983, Casio launched the tough watch "G-SHOCK," which enhanced shock resistance and vibration resistance for harsh environments, surprising the world. It significantly exceeded ISO standards for shock-resistant watches, demonstrating high shock resistance capable of withstanding impacts from intense sports and continuous vibrations from chainsaws and rock drills. This revolutionized the lifestyles of people worldwide and established a category of wristwatches known as "tough watches." In addition to its high functionality, its distinctive form has been recognized, and in 2023, it became the first wristwatch to be registered as a three-dimensional trademark by the Patent Office in Japan. The reissue of the iconic "First Generation G-SHOCK" faithfully reproduces the original design. Over 40 years since the brand's inception, G-SHOCK has continuously evolved, introducing numerous models. This special model embodies the intentions and hopes for the future inherent in the original model, brought to life through the technology of contemporary G-SHOCK. The case is made of stainless steel, just like the original, and the band replicates the length, shape, and position of the dimples of the original model. It reflects G-SHOCK's determination to return to its original intent and pave the way for the future. Meanwhile, the bezel and band materials utilize biomass plastic to reduce environmental impact. An LED backlight enhances visibility. The case size has increased from the original model's 41.6mm to a modern 42.3mm. The bezel, carefully recreated from the original model, features a flat design for the "PROTECTION" and "G-SHOCK" inscriptions, faithfully reflecting the original. The face design incorporates red, blue, and yellow, representing G-SHOCK's brand colors and the passion for continuous challenge. The red symbolizes this passion, blue signifies high water resistance, and yellow indicates shock resistance. A brick pattern that evokes robustness has also been adopted. The beautifully mirror-polished screw-back case layout and the dynamic "Shock Resistant" inscription evoke the original model, with attention to detail throughout. This model is crafted by artisans and engineers at "Yamagata Casio," the mother factory of G-SHOCK, honoring the technicians who completed the original model. - Shock-resistant structure - 20-bar water resistance - Stopwatch (1/
