Casio G-Shock × Toyota Gazoo Racing GA-2100 — The First-Ever GR-Branded CasiOak, on Sale at Rally Japan 2026

Description

The Casio G-Shock × Toyota Gazoo Racing GA-2100 is the brand's first G-Shock to carry the Toyota Gazoo Racing (GR) badge on the dial, and one of the cleanest motorsport collaborations Casio has executed on the slim octagonal GA-2100 'CasiOak' platform to date. The watch goes on sale on 28 May 2026 — the opening day of the FIA World Rally Championship's Forum8 Rally Japan 2026 event at Toyota Stadium in Aichi Prefecture — and commemorates driver Takamoto Katsuta's first WRC overall victory, scored at the Safari Rally Kenya 2026.

This is not a livery-dial cosplay piece. The watch is almost entirely matte black: case, strap, dial, and inset digital sub-display share the same finish. The Gazoo Racing wordmark sits at the top of the dial in silver, mirrored by the silver of the two analog hands. The only colour break on the entire watch is a single red day-of-week indicator at the 9 o'clock position — a deliberate WRC livery callback executed with the kind of restraint that Casio's earlier Toyota collaborations have not always managed.

Design

The case carries the now-iconic octagonal GA-2100 'CasiOak' silhouette — 48.5 mm × 45.4 mm × 11.8 mm, carbon-core-guard construction, 51 grams on the wrist — and is finished in all-matte black with no contrasting bezel insert, no lacquered livery, no printed graphics. The Gazoo Racing logo is rendered in matched silver typography at 12 o'clock, and the only deviation from the standard GA-2100 dial layout is the small red day-of-week indicator embedded in the digital sub-display near the 9 o'clock position.

The strap is the most distinctive design departure on this reference. Where the standard GA-2100 strap carries three profile grooves running down its length and recessed adjustment holes, the Toyota Gazoo Racing edition uses two grooves rather than three, non-recessed adjustment holes, and a fully printed 'TOYOTA GAZOO RACING' wordmark running down the outboard edge of the band. The 200 m water resistance, the screw-on caseback, and the double LED Super Illuminator backlight are all carried over unchanged from the base GA-2100.

What's Exciting

The GA-2100 has been the chassis of choice for nearly every meaningful G-Shock collaboration since 2020 — Ron Herman, John Mayer × Hodinkee, GORPCORE editions, Polar Bear, Nissan GT-R — but Casio has noticeably avoided giving it a factory-Toyota dial until now. The GR partnership matters because it is the first time Toyota's competition sub-brand has been allowed to sign a G-Shock in its own typography, rather than via the broader Toyota lifestyle catalogue. And the execution is editorially disciplined in a way that most motorsport-branded watches at this price point are not: the all-matte-black case, the single red day-of-week pop at 9 o'clock, the restrained Gazoo Racing wordmark at 12 — it reads as livery without ever turning into cosplay. At JPY 24,200, this is the rare 2026 G-Shock motorsport collab that prices within reach of normal collectors rather than carrying the JDM-secondary-market enthusiast tax usually attached to limited GR-branded merchandise. The catch is the JDM-only rollout, which will almost certainly drive grey-market pricing above face once the May 28 retail wave clears.

History

Casio introduced the original G-Shock — the DW-5000C, designed by Kikuo Ibe — in April 1983, founding what has become the most commercially significant analog/digital wristwatch line of the past four decades. The GA-2100 'CasiOak' launched in August 2019 and, by the early 2020s, had become the brand's most-discussed everyday-wear analog-digital reference, almost entirely on the strength of its Royal-Oak-adjacent octagonal bezel-on-case silhouette and the absurd price-to-design ratio that places it on enthusiasts' wrists worldwide.

Toyota Gazoo Racing is Toyota's competition arm, founded in 2007 at the Nürburgring 24 Hours and elevated to a full motorsport sub-brand in 2017 — the season Toyota returned to the World Rally Championship. TGR-WRT (Toyota Gazoo Racing World Rally Team) has since won the WRC manufacturers' championship in 2018, 2021, 2022, 2023, 2024, and 2025 — six titles in eight seasons. Takamoto Katsuta, the driver this watch commemorates, joined the TGR factory line-up in 2020 and became the first Japanese WRC overall race winner since Kenjiro Shinozuka in 1997 when he won the Safari Rally Kenya 2026 earlier this season. The G-Shock × Gazoo Racing GA-2100 is the merchandise expression of that result and the first formal Casio × GR collaboration on a G-Shock.
