G-Shock GW-8230B-9A Titanium Gold for Frogman 30th Anniversary

G-Shock GW-8230B-9A Frogman ISO Diver's 200M

In celebration of the 30th Anniversary of G-Shock’s signature diving line, Casio is releasing a limited edition Frogman watch inspired by the second-generation Frogman DW-8200 (and specifically the black and gold DW-8200B-9A). While it appears to be another Frogman GF-8250 model at first glance, the GW-8230B-9A is the first model of an all-new series and includes upgrades over the GF-8250 such as a titanium case and an LED backlight. Other features include Tough Solar power, tide and moon graphs, and diving and interval time measurement with dive log. Taking a cue from recent Pro Trek models, the bezel and band are made from eco-friendly biomass plastics. Leaked catalog images show that the watch has a Frogman character image on the backlight and a special Frogman 30th Anniversary case back design.

Based on the “GW” prefix, it would be logical to expect the watch to have the Multi-Band 6 radio timekeeping feature (a.k.a. “Waveceptor”), but apparently it does not have it. There is no “received” indictor on the display, and leaked catalog images do not list Multi-Band 6 as a feature. Also based on the catalog image, the module is 3521, and the Japanese instruction manual (casio.jp) does not list Multi-Band 6 in the specifications.

The Frogman line, introduced in 1993 with the DW-6300, is known for its ISO Diver’s 200M water resistance and made-in-Japan status. (The GW-8230B-9A features a “Japan” label next to the Shock Resist logo on the face.) Prior to the release of the analog GWF-A1000 with a carbon monocoque case, it was also known for its stainless steel or titanium screw-back cases.

The GW-8230B-9AJR will be released in October in Japan and is expected to get a wider release. This post will be updated with additional images and information.

it is very cool, though if it is ok to charge daily, then the new Apple Watch Ultra gives strong competition…
