When talking about the ultimate all-digital G-Shock watch, the Frogman is always part of the conversation. It lost some ground recently to the feature-rich and value-minded Rangeman and is now more of a prestige watch than a practical choice, but to many fans it will always be Casio’s flagship G-Shock. The made-in-Japan Frogman has a reputation as one of the best built G-Shock watches and its limited edition models tend to have the most value as collectibles. The Frogman line has a rich history that goes back to the early 1990s. It was always known for being the lone ISO-compliant diving watch in the G-Shock lineup, having a screw-lock case back, and an extra-large, asymmetrical design. Those qualities live on in the GWF-1000 and GF-8250 models with stainless steel replacing the titanium cases of the previous generation, and they also have Tough Solar power, a tide graph, and moon age data. The GWF-1000 adds Multi-Band 6 radio wave timekeeping for the first time and has a DLC (diamond-like carbon) coating on the case back for rust and corrosion resistance. The size of the GWF-1000 is 58.3 x 52.8 x 18.0mm and the GF-8250 is 52.0 x 50.3 x 18.0mm. The list price of the GWF-1000 is $700 and the latest GF-8250 model was $530.
With the GF-8250 series, Casio seems to be continuing the limited-edition Frogman tradition of the GW-200 series, though on a less frequent basis. While the standard GWF-1000 Frogman looks like it was inspired by 1995’s second-generation DW-8200 Frogman (but goes a lot bigger with the outer resin case), the GF-8250 is more of a direct revival of that model. Like the GWF-1000 it adds size and heft but remains very similar to the DW-8200 with the engraved G-Shock logo on the exposed stainless steel bezel and similar shapes and angles on the resin case.
Update: In 2016 Casio released the GWF-D1000 Frogman, which retained a similar design as the GWF-1000 and added a water depth meter, compass, and thermometer. Billed as a Triple Sensor watch, the GWF-D1000 does not have an altimeter/barometer pressure sensor like other Triple Sensor G-Shock and Pro Trek watches. The GWF-D1000 is the largest Frogman yet and measures 59.2 × 53.3 × 18 mm. Casio America released the GWFD1000B-1 with a list price of $1,050. While the GWF-1000 appears to still be in production, it looks like the GF-8250 has been retired.
Here are all the GWF-1000, GF-8250, and GWF-D1000 Frogman models ever released starting with the most recent.
