Casio’s motorsport-themed Toyo Tires G-Shock is finally getting a wider release

Casio has officially expanded the availability of its new special-edition DW-5600, created in collaboration with Japanese high-performance tire manufacturer Toyo Tires. Dubbed the G-Shock DW5600TT25-1, the motorsport-inspired timepiece is now available for purchase directly through Casio’s U.S. online store for $150.

Previously, the watch was exclusively available through BAIT’s Diamond Bar store in California and its dedicated online launch site. But the broader release means collectors and automotive enthusiasts can get their hands on the collaborative square G-Shock without having to navigate limited boutique drops.

For the uninitiated, the DW5600TT25-1 takes design cues from Toyo’s extreme-performance summer tire, the Proxes Sport R, pairing a high-contrast white dial with a black resin case and band, which are decorated with intricate tire tread graphics.

The resin band prominently features Toyo Tires and Proxes logos printed in white, complemented by stylized “R” graphics near the lower edge, while the dial and bezel are imprinted with Toyo Tires, Casio, and G-Shock branding. On the case back, you will find these same details engraved into a design mimicking a tire sidewall. Meanwhile, activating the LED backlight reveals a hidden blue Proxes “R” logo on the display

The G-Shock DW5600TT25-1 arrives in a blue presentation box and a custom black metal tin designed to look like a wheel-and-tire setup.

Beyond the custom styling, the DW5600TT25-1 remains a classic G-Shock square, offering Casio’s shock-resistant construction, 200 meters of water resistance, a 1/100-second stopwatch, countdown timer, multi-function alarm, flash alerts, full auto-calendar, and LED backlight with afterglow in a wearable 48.9 × 42.8 × 13.4 mm case.
