The iconic AW-500G, originally launched in 1989, has now been reissued in an eye-catching all-metal edition. The dial features the original shock-absorbent gold-print graphics, harking back to the early days of G-SHOCK. Current diamond-like carbon coating technology ensures a highly scratch-resistant stainless steel bezel and an elegant black stainless steel bracelet. This isn’t just a nostalgic revival. This is a watch equipped with the latest Casio technology for full functionality.
For this collaboration, PORTER provides a unique case that pays homage to the watch’s original graphics and design. The hinge is inspired by the red hour hand and the golden minute hand. The same shock resistance chart is embossed in gold on the top of the case.
