To celebrate Seiko’s partnership with Supercars, it has released its very first Seiko 5 Sports GMT Supercars limited edition ahead of the 2026 season.
Seiko has been the official timing partner with the Supercars Championship and Team 18 Racing since 2014. But never have they had a limited edition GMT to celebrate. Until now, that is. And why not? The Supercars Championship has evolved over the years, and spread its wings to now racing across Australia and New Zealand, and as such, spans six different time zones.
“The Supercars Championship spans incredible locations and time zones across Australia and NewZealand, bringing passionate fans together wherever the series races. The GMT function on the new Supercars watch is our tribute to everystop on the calendar and to the amazing fans in each location. We’re proud of our long-standingpartnership with the Supercars Championship and excited for another great season ahead.”
Daniel Findlay, Seiko Australia Marketing Manager.
And it is a good-looking watch. With similar design cues as last year’s Seiko 5 Sports Supercars Edition in the red and black colourway, the new 2026 model takes the race styling to the next level. With a carbon fibre-patterned dial, it echoes the material used in the cars – lightweight and flexible, and this is a design that makes its way to the leather strap as well.

The red highlights echo the racing vibes (red goes faster, right?!) used on the GMT hand, the chapter ring and the stitching on the strap. The GMT bezel is broken into black and grey, for the night and day parts, which just amplifies the sporty nature of the Seiko 5 Sports Supercars Edition.
Inside the watch is the Seiko calibre 4R34. It is a calibre that is reliable and robust, like most Seiko movements. This draws parallels to motorsport, which is driven by engineering, passion and precision – all virtues that Seiko also upholds. Beating at 3Hz / 21,600 VpH, and with a 41-hour power reserve, has an accuracy rating of +45 / -35 seconds per day. While this is not amazing compared to other higher-end movements, from experience, the paper specs do differ a lot from real-world experience when it comes to Seiko. My Seiko Prospex Turtle “Kame” keeps to about +13 seconds per day with the 4R36 movement. Big difference!

On the caseback, you have a see-through sapphire crystal, showing the 4R34, and the Supercars logo emblazoned on the crystal. Each piece is a limited edition of 1,500 pieces, individually numbered, but each is randomised on purchase.
Seiko has included a special edition box, commemorative pin, a branded cleaning cloth, and an individually numbered certificate detailing all Supercars racetracks, making it a true collector’s piece, especially for those who are Supercars fans.
Initial Thoughts
Last year, the Watch Advice team had the pleasure of doing some hot laps out at Queensland Raceway with Team 18, thanks to Seiko Australia. Sitting in the passenger side of the Camaro ZL1, next to Team 18’s Supercar driver, Anton De Pasquale, we got a very different perspective of the racing that these cars and drivers do. Even just being in the pits, hearing the loud, throaty rumble of the cars, there is something about the sound of a fully worked 5.7L V8 punching out 600HP that makes you get goosebumps!



Racing aside, I understand the association between Seiko Australia and the Supercars. Unlike Formula 1, which is all about pushing the technical boundaries and super high-end materials, performance, and not to mention a lot of money, Supercars are grounded in the grass roots, which is the very origins of the sport itself. Production cars would race to test each manufacturer’s ability and endurance. Seiko watches have the same kind of ethos – rugged durability, reliability, and genuinely sporty, yet priced so that enthusiasts don’t have to treat ownership like a financial event.
With the Seiko 5 Sports Supercars Limited Edition, race fans and collectors can get in on the action, and at A$850, it is at a price point that most collectors and watch lovers could reasonably afford. Although I’ll caveat that with price and affordability is subjective and based on the individual, but I’m speaking generally here and in relative terms to the overall watch market.
It is also not so heavy on the Supercars theming, meaning that even if you’re not a race fan, but a watch lover in general, you can purchase this and wear it as a daily, and it will still look good on the wrist!
