Casio celebrates the 40th anniversary of its shock-resistant watch, G-SHOCK, this year (2023). On November 28th, the GCW-B5000UN series will be released as a special commemorative square model, paying homage to the first model launched in 1983. The lineup includes two striking models: the black GCW-B5000UN-1JR and the purple GCW-B5000UN-6JR.


In recent years, G-SHOCK has embraced the utilization of carbon, a material that is seven times stronger than stainless steel and significantly lighter. The GCW-B5000UN series continues this trend with its innovative use of carbon.

The forged carbon bezel and band offer unparalleled freedom in shaping, while the clasp is made of laminated carbon, providing exceptional resistance against bending. The monocoque case, featuring an integrated back cover, is crafted using carbon fiber-reinforced resin. As a result, the GCW-B5000UN series weighs approximately 65% less than the stainless steel GMW-B5000D series, making it 61% lighter and perfect for everyday wear.

Experience the Power of Forged Carbon


The bezel and band of the GCW-B5000UN series are crafted from forged carbon, a composite material commonly used in aircraft fuselages. This material is created by blending carbon fiber with resin, which is then forged in a press die under high temperature and pressure. The result is a strong and lightweight component with intricate molded forms, including unique dimpled sections. From every angle, you can appreciate the distinctive fibrous patterns that grace the entire exterior of the watch.
