Casio is expanding its Master of G lineup in Japan with two new models: the Sea Frogman GWF-D1000BC-1 and the Land Mudmaster GWG-B1000-1A3.
Both watches are set for release this month and are designed for specific utility in diving and outdoor environments.
The company has chosen a subdued design for these releases, using black, olive green, and tan color schemes instead of bright accents.
Pricing and design details
The Sea Frogman GWF-D1000BC-1JF is the more expensive of the two, priced at ¥198,000 ($1,288).
It is built specifically for diving, carrying an ISO-standard 200-meter water resistance rating.
The watch includes a Triple Sensor array featuring a thermometer, a digital compass with automatic horizontal compensation, and a depth gauge that measures down to 80 meters in 10-centimeter increments.
For hardware, the Frogman uses a composite bracelet made from a mix of metal and fine resin, with a two-stage extension mechanism for wearing over a wetsuit.
The case features a DLC-coated stainless steel bezel, sapphire crystal glass, and a screw-lock case back.
It relies on Casio's Tough Solar charging and Multiband 6 radio-controlled timekeeping.
The Land Mudmaster GWG-B1000-1A3JF is priced at ¥132,000 ($858) and is designed for land-based use.
It is built around Casio's Carbon Core Guard structure, featuring dust, mud, and vibration resistance.
This model pairs a black, multi-textured case with a matte olive-green band and tan dial markings.
The Mudmaster's sensor array differs from the Frogman, swapping the depth gauge for an altimeter and barometer, alongside a thermometer and compass.
It also adds Bluetooth connectivity, allowing users to access automatic time adjustments, mission logging, and location tracking via the Casio Watches app.
Both the Frogman and the Mudmaster incorporate biomass plastics in their resin components, a material Casio has been integrating into its G-Shock lines to reduce environmental impact.
In related news, Casio recently launched three new Master of G watches in the US with a Horizon Gold finish, along with an Apple Watch-shaped moon-phase watch featuring a silver dial.
