The Casio G-SHOCK MUDMASTER GWG-B1000TLC-1A is a Team Land Cruiser Toyota Auto Body collaboration inspired by the Dakar Rally’s nighttime stages. It pairs rally-themed colors and a moonlit-desert band design with solar power, radio time calibration, Bluetooth, and a triple sensor. Casio’s Japan listing gives a February 2026 release and a Japan-specific suggested retail price of ¥140,800 including tax.
What is the GWG-B1000TLC-1A?
It is a special-edition G-SHOCK MUDMASTER made in collaboration with Team Land Cruiser Toyota Auto Body (TLC). Casio describes the design as inspired by “the grueling nighttime legs of the Dakar Rally.” That is the stated design inspiration; it does not establish that this watch was tested or used in competition. Casio’s international product page identifies the model and collaboration.
How the design reflects rally navigation and a night desert
Casio says the red, blue, and yellow dial accents draw on information colors used on the rally vehicle’s navigation display. The band’s printed pattern evokes sand dunes, while the gold-colored band loop represents the moon. Collaboration logos and an engraved case back add team-specific details; the dedicated packaging uses recycled materials. These are visual references rather than evidence of rally equipment or navigation capability.
What functions does it offer?
Timekeeping and connectivity
The watch combines solar-powered timekeeping with radio time calibration and Bluetooth connectivity. The solar system supplies charging, while radio calibration and Bluetooth are separate time-adjustment and connection features listed by Casio.

Triple sensor and Location Indicator
Casio lists a triple sensor that measures direction, altitude, barometric pressure, and temperature. Its Location Indicator works with the companion app: set a destination through the app, and an indicator hand points in that direction. It is a directional indication toward a selected point—not turn-by-turn guidance, route planning, or a replacement for dedicated navigation equipment.
Construction and size
The case uses carbon-fiber-reinforced resin with metal exterior components. Casio specifies shock, dust, mud, and vibration resistance, sapphire crystal, and double LED illumination. The UK product listing specifies 200-metre water resistance and gives the following dimensions and weight:
Rank #2
- Enjoy both fearless adventure and a comfortable fit with this tough and rugged Master of G Mudmaster flagship timepiece
- This analog-digital combination watch delivers more comfortable fit and outstanding durability with a robust exterior incorporating a guarding structure built with metal components
- The comfortably sized GWG-B1000 features a metal exterior crafted with high-precision forging techniques and a carbon fiber-reinforced resin case that offers high strength and outstanding durability
- Case dimensions: 58.7 × 52.1 × 16.2 mm
- Weight: 114 g
- Water resistance: 200 metres
Those figures make size and weight useful considerations for anyone comparing it with other watches, particularly if they prefer a smaller or lighter case. The analog-digital display, sensor functions, app connection, charging and time adjustment, and resistance specifications are other practical points to compare; the listed specifications alone do not establish that it outperforms another model.

Best Value
- Perfect Fit for GWG-2000 with Specialized Connectors: Engineered exclusively for the Casio G-Shock GWG-2000, this strap comes with GWG-2000 Specialized Connectors for a seamless, gap-free, and secure installation that matches the OEM look and feel, ensuring your watch remains rugged and reliable.
- Tough, Breathable Nylon Built for the Outdoors: Made from high-density nylon webbing, this strap is engineered for durability where it counts. It resists scuffs, abrasion, and dries fast after river crossings or rain, outlasting standard materials. The breathable fabric and venting design let your skin air out, banishing the swampy feel of rubber straps during long hikes or hot days, keeping you focused on the adventure ahead.
- Quick-Adjust & Secure Magic Tape Closure: Experience effortless, perfect-fit adjustments in seconds. Unlike buckle systems, the Powerful Magic Tape (Hook & Loop) closure allows for infinite micro-adjustments and provides a supremely secure lock that won’t come undone accidentally, offering a custom fit that standard straps can't match.
- Rugged, Tactical Style That Matches Your G-Shock’s Spirit: Don’t just change the strap—elevate its presence. Our high-density nylon band is engineered for a robust, tactical look that fully complements the GWG-2000's legendary tough build. Featuring bold woven labels like "MASTER OF SHOCK", contrasting stitching, and signature reflective accent patches (including a standout triangular patch), it reinforces a rugged, ready-for-anything aesthetic. Even when swapped from the factory rubber, the watch loses none of its iconic, hard-wearing character—it gains a personalized, mission-ready edge that’s perfect for outdoor adventures and assertive daily wear.
- Personalized Style with Easy Size Selection: Refresh your GWG-2000 with bold, personalized flair. Available in multiple colors (Black/Red, Orange, Olive Green, etc.) to match your gear or mood. Includes a clear sizing guide—just measure your wrist to choose between Medium (7.4"-8.6") or Large (8.4"-9.6") for a tailored fit that generic one-size straps cannot provide.
