Casio has officially listed the GW-BX5600-1JF and 1A1JF for purchase in Japan. They're both priced at ¥30,800 (~$200). The product pages have full MIP LCD photos, design details - including biomass resin parts - and two distinct display styles.

After yesterday's news regarding Casio's anticipated GW-BX5600 watches being available to buy today, the Japanese manufacturer has followed through, and now, this is the first time both the GW-BX5600-1JF and the GW-BX5600-1A1JF can be directly purchased on Casio's Japan website. The watches are listed with full product photos, info, and pricing. Each model is priced at ¥30,800 (tax included). There's no new information on the product pages per se, so given below are detailed specs and features that are the reason behind the aforementioned watches' hype.

The product images show two display modes - Standard and Classic - using the new MIP LCD panel. The comparison makes the readability upgrade even more obvious, especially with the way the digits hold contrast under different lighting. The product pages also showcase the original 5600-series footprint. Both watches stick close to the classic DW-5600 shape but shift the internals to a combination of Tough Solar, Bluetooth smartphone sync, and Multiband 6 radio reception. An explicit note on the page states that the solar panel carries a brick-like pattern similar to early G-Shock designs.

Casio’s use of biomass plastic for the bezel, band, and case components is also quite nice. It’s the same move seen in a few recent G-Shock releases. Between the two variants, the difference is mainly the finish. The 1JF keeps a subtle color trim around the display border, while the 1A1JF is a full blackout version with no accents. This gives the 1A1JF a slightly more utilitarian look.

Functionally, nothing new is revealed - you still get phone-based time correction, automatic radio sync, and four different display styles that can be switched using the app. Also, both models are marked as "Store inventory directly managed", meaning the online store is handling stock rather than redirecting to retailers. With the full listings now live, these watches are essentially ready for purchase. However, considering forums have been buzzing with mentions of these GW-BX5600 models for a while now, interested buyers might want to act fast before stocks run out.

Buy the Casio GWM5610-1 on Amazon.
