What is the famous “DW-5900” that determined the value of G-Shock?

Casio’s “G-Shock” is one of Japan’s world-class wristwatches, known for its rugged and durable gear. Today, G-Shock is synonymous with toughness, but only fans of yesteryear would know that its popularity was somewhat muted for some time after its shocking debut. It was the “5900” series that made the G-Shock a fashion item…or rather, a piece of gear that has remained unshakably popular. In 2018, the 35th anniversary of the brand, a reissue model was introduced, focusing on the unique form of this model.

The ” G-Shock ” – the exact opposite concept in an era of smaller, thinner watches

The first G-Shock model was introduced in 1983. At that time, thin and lightweight digital watches were the mainstream, and it was commonplace to make smaller and thinner circuits as if to show off the high level of technology. The history of G-SHOCK began with a single line of a proposal that read, “A watch that won’t break even if dropped.

G-SHOCK’s shock-resistant structure broke the rules of the time with its “Triple 10

The first G-Shock, the “DW-5000C,” was completed as a result of repeated trial and error during the development stage, with the goal of achieving the “Triple 10,” which was to withstand a 10-meter drop impact, have a 10-year battery life, and be water resistant to 10 atmospheres. The DW-5000C was the result of repeated trial and error with the goal of achieving the “Triple 10,” which was to have “waterproof performance.” The DW-5000C was covered entirely with urethane resin and had a hollow structure that supported the engine at points (a technique of placing the engine so that it floated within the case to prevent direct impact on the module), a feat that has been carried on as core technology in current G-Shock watches. The G-Shock was released at a time when it was common knowledge that “watches = precision instruments = weak against shocks, weak against water, and stop immediately,” and it sent shockwaves around the world.
