Casio's motorsport G-Shock DW5600TT25-1 puts Toyo Proxes tire tread on your wrist for $150

Casio's square G-Shock has been the brand's blank canvas for collaborations for years, and the latest partner comes from the automotive side rather than fashion or streetwear. The Casio G-Shock DW5600TT25-1 pairs the DW-5600 platform with Toyo Tires, a Japanese tire maker, and themes the whole watch around the company's new Proxes Sport R extreme-performance summer tire. It launches in the U.S. on June 14 for $150.

What's new

The DW5600TT25-1 is a cosmetic build on a familiar chassis. Casio started with the standard square G-Shock and reworked the case and band in black resin stamped with a tire tread pattern, then added a white dial to break up the usual all-black look. The contrasting blue band loop is the detail that ties the design together, and Casio carried that blue into the Toyo Tires, Casio, and G-Shock branding for a coordinated motorsport theme rather than a random sticker job.

The band carries Toyo Tires and Proxes logos printed in white, with stylized "R" graphics near the lower edge that reference the Sport R name. Flip the watch and the case back is engraved to resemble a tire sidewall, which is a nicer touch than the flat steel backs on most base-model G-Shocks. The standout gimmick is in the display: activate the LED backlight and a blue Proxes "R" logo appears on the screen. Casio has done custom EL backlight art before on editions like the Korea-exclusive Gundam tie-in and the G-Shock x Challenger, so the mechanism is proven, and it reads as a deliberate collector feature rather than a throwaway.

Collectors also get the packaging. The watch ships in a blue presentation box plus a collectible black metal tin shaped like a wheel-and-tire setup, with tread detailing and Toyo Tires and Proxes branding. Tins like this tend to drive resale value on limited G-Shocks more than the watch finish itself.

How it compares

Mechanically, nothing here departs from the DW-5600 you can buy for far less. The DW5600TT25-1 measures 48.9 x 42.8 x 13.4 mm and weighs 52 grams, the same compact, light footprint that has kept the square in rotation as an everyday watch. You get Casio's shock-resistant construction and 200 meters of water resistance, a 1/100-second stopwatch, countdown timer, multi-function alarm, flash alerts, a full auto-calendar through 2099, and an LED backlight with afterglow. Battery life is rated at roughly five years on a single CR2016 cell, which is the trade-off for skipping solar charging on this module.

That puts the value question in sharp focus. A plain DW-5600UE-1V runs about $65, so the Toyo collaboration commands a $85 premium for the tread-pattern resin, white dial, custom backlight logo, engraved case back, and the metal tin. Buyers cross-shopping against solar or Bluetooth-equipped squares like the GW-B5600 should know the TT25-1 has none of those upgrades. The price is entirely about the design and the packaging, not added function. Compared with other recent collaboration squares, $150 is in the normal range, neither the bargain end nor the premium metal-cased territory.

Who it's for

This is a collector and enthusiast piece first. If you follow G-Shock collaborations, track car culture, or specifically want a watch tied to Toyo's Proxes line, the tread resin, hidden backlight logo, and wheel-shaped tin justify the buy. The compact case and 52-gram weight mean it still works as a daily beater, so it is not purely a shelf piece. Anyone who just wants the core DW-5600 experience, shock resistance, 200 m water resistance, and five-year battery, is better served by a standard square at less than half the cost.

Availability is staged. The Casio G-Shock DW5600TT25-1 x Toyo Tires goes on sale Sunday, June 14, at BAIT's Diamond Bar store in California, with online sales starting Monday, June 15, at 12 PM PDT through BAIT's dedicated launch site. Casio will also stock it on its U.S. online store, though the exact timing is not yet confirmed. BAIT is adding a limited BAIT x Toyo Tires T-shirt at the launch event for buyers who want to complete the set.
