40th anniversary 5000-line timepieces deliver high strength and reduced weight

TOKYO, Nov. 10, 2023 /PRNewswire/ -- Casio Computer Co., Ltd. announced today the release of new additions to its line of shock-resistant G-SHOCK watches, designed to celebrate the 40th anniversary of the G-SHOCK brand. The new GCW-B5000UN, available in two models, joins the 5000 line, inheriting the iconic form of the very first G-SHOCK and employing carbon materials to achieve both high strength and reduced weight.

GCW-B5000UN

The new GCW-B5000UN joins the 5000 line of watches that inherit the iconic shape of the first G-SHOCK. Now, however, it achieves the shock-resistant form with components made using carbon materials created in different production processes.

The timepiece employs different types of carbon materials for the case, bezel, band, and clasp to accommodate the watch's complex structure, achieving a light weight, at just approximately 65 g, 61% lighter than its full-metal predecessor, the GMW-B5000D made with stainless steel, which weighed around 167 g.^[*1]

[*1] Weights are catalog-specified values.

Forged carbon,^[*2] which enables molding with a high degree of flexibility, is used for the bezel and band, while multilayer carbon is employed for the clasp's folding arm due to its high bending strength. Also, the monocoque case and integrated case back are made with carbon fiber-reinforced resin.

The design combines the G-SHOCK never-ending commitment to innovation with imagery inspired by the unfathomable, infinite expanse of outer space with a motif inspired by the Big Bang and galactic planets. The two-model lineup offers a choice between purple, featuring mixed-color molding with opal specks,^[*2] and basic black.

[*2] Due to the characteristics of forged carbon, a composite material produced by molding a mixture of carbon fiber and resin, there are individual differences in the pattern, color tone, and distribution/amount of opal specks on the surface of each part (bezel, band, and clasp) for each timepiece. Opal specks are not included in the clasp components.
