Key Takeaways
1. A new model number for the GMW-B5000 was found in an Asian certification database, indicating another variation coming after the BZ5000 release.
2. Two main rumors suggest Casio may revisit classic designs, aligning with their pattern of updating models every few years.
3. The BZ5000 targets the high-end market with upgraded features, but concerns about market oversaturation exist due to numerous existing B5000 variants.
4. Current pricing for the GMW-B5000D-1JF is around ¥60,000 (~$415), lower than its 2018 launch price, but new variants may exceed ¥70,000 (~$484).
5. Casio’s certification records indicate a new GMW-B5000 version is likely on the way, possibly a fully-titanium model or another color option.
We recently discussed the Casio GMW-BZ5000, which generated significant excitement, a common occurrence with the company’s all-metal square models. In a recent update, thanks to Great G-Shock World, a new model number for the 2018 GMW-B5000 has appeared in the same Asian certification database that revealed the BZ5000 a few weeks ago. This filing strongly suggests at least one additional variation of the watch that started the full-metal G-Shock trend, and the documents indicate it will be released after the BZ5000 hits stores—likely late this year or early 2026.
Rumors From Tokyo
The blog post features two primary rumors circulating in Tokyo’s reseller communities:
While neither rumor is confirmed, both seem to fit Casio’s pattern of revisiting their classic designs every few years.
From a collector’s perspective, the timing is logical. The square-case BZ5000 (with its updated display and MIP crystal panel) targets the higher end of the market—produced in Japan, rumored to be priced in the four-figure range, and featuring a design that’s already gaining attention. However, one might question if yet another color adjustment is sufficient. The B5000 lineup is already filled with standard steel options, “Bruised Blue” IP, rainbow ion, Aged IP, gold, among others. Unless the new reference introduces a significant material upgrade (like titanium), the potential for market oversaturation is a genuine concern.
Pricing Insights
Local listings price the stainless GMW-B5000D-1JF in the low-¥60,000s (about $415)—not cheap, but significantly lower than its launch price in 2018. A black IP or titanium variant would likely exceed the ¥70,000 (~$484) mark, yet still be cheaper than the BZ5000’s rumored price tag of ¥100,000 (~$692) or more.
Casio’s certification records are typically reliable, so a new GMW-B5000 version is almost certainly forthcoming. It might be a fully-titanium model or simply another color option. As soon as we receive the reference number or a teaser image, we’ll provide an update.
