Casio G-Shock GMW-B5000 Series

The G-Shock brand was originally developed by Casio engineer Kikuo Ibe in 1981, with the first model, the DW-5000C, debuting in 1983. The brand was built on the 'Triple 10' concept: water resistance to 10 bar, a 10-year battery life, and the ability to survive a 10-meter drop. This specific model, a metal-cased GMW-B5000 unit, represents the high-end evolution of that original design, featuring modern technology like Bluetooth connectivity and Tough Solar power.

While many G-Shock models are manufactured in China or Thailand, the GMW-B5000 series is part of the premium 'Full Metal' line. These specific timepieces are typically produced at Casio’s high-end Yamagata factory in Japan, known for its advanced automated assembly and precision engineering. The brand remains under the ultimate ownership of Casio Computer Co., Ltd., a multinational electronics corporation headquartered in Tokyo, Japan, ensuring a legacy of innovation and durability that has spans over four decades.
