TAG Heuer Carrera x Team Ikuzawa Revives 1970s Roadmaster Stopwatch DNA

TAG Heuer just released the Carrera Chronograph x Team Ikuzawa, a 39 mm Glassbox limited to 150 pieces that pulls its dial language straight from the team’s 1970s Roadmaster stopwatches. Priced at USD 10,500 (EUR 10,450 / CHF 9,900), the watch pairs a white Clou de Paris dial, heavy red accents and a sponsor-style layout with the brand’s modern TH20-10 manufacture chronograph.

Three years after the first Bamford-involved 42 mm edition, Mai Ikuzawa and George Bamford returned to the archives. The result feels less like a logo collab and more like a wearable timing instrument from the Japanese racing pits of the 1970s and 1980s.

Inside the 39 mm Steel Case

The case keeps the successful Glassbox architecture introduced in 2023: brushed and polished stainless steel, 39 mm diameter, roughly 13.9 mm thick, 46 mm lug-to-lug. A domed sapphire crystal with double anti-reflective coating flows over the sloping flange with no traditional bezel. The screw-down crown carries a red lacquered ring and sits between vintage-style pushers. Water resistance is 100 metres. The sapphire caseback shows the TH20-10 movement plus Team Ikuzawa and Bamford Watch Department engravings and the individual number.

Reference is CBS221M.EB0435. Power comes from the automatic manufacture calibre TH20-10: column wheel, vertical clutch, bidirectional winding, 4 Hz, 80-hour power reserve. Functions cover hours, minutes, date and chronograph (central seconds, 30-minute counter at 3, 12-hour counter at 9). No running seconds subdial appears.

Column-wheel control and a vertical clutch give the chronograph a direct, mechanical start-stop action suited to pit timing. Bidirectional winding keeps the 80-hour reserve topped up in daily wear. At 4 Hz the balance delivers the smooth central seconds sweep expected on a modern manufacture chrono, while the date remains the only non-timing display on the dial.

The seven-row steel bracelet is the default. Two extra straps ride along: perforated white leather with red stitching and a white textile strap with red stripes that echo the team’s historic livery.

Together the 46 mm lug-to-lug span and the absence of a raised bezel keep the watch compact on the wrist. The Glassbox crystal softens the edges of the 39 mm steel so the piece reads smaller than a traditional flat-crystal Carrera of the same diameter.

Roadmaster Graphics Take Over the Dial

The white dial uses a Clou de Paris texture that catches light like a vintage instrument face. Printed black hour markers and a black flange with white minute track replace the applied indices of most modern Carreras. Red appears everywhere that matters: lacquered hour and minute hands (rhodium-plated facets with Super-LumiNova and red tips), the central chronograph seconds hand, TAG Heuer and Carrera logos, and every numeral on the angled date wheel at 6.

Above the date sits the Team Ikuzawa signature. That space normally holds a running seconds hand. Removing it frees the dial for team identity the same way classic Heuer racing chronographs left room for sponsors. The 30-minute counter at 3 o’clock carries a distinctive pinball-style ring; the 12-hour counter at 9 stays clean. No tachymeter scale circles the dial.

Those choices are not random. Mai Ikuzawa and Bamford studied the team’s original Roadmaster stopwatches from the 1970s and 1980s. High legibility, bold red-and-white contrast and stopwatch-first graphics were the priorities then. The new Carrera copies that hierarchy instead of adding more complications.

Printed markers sit flatter than applied metal, so the eye tracks the red hands against the Clou de Paris field without depth competition. The pinball ring on the 30-minute totaliser becomes the only decorative flourish; everything else serves elapsed-time reading. That restraint is what makes the dial feel like a pit instrument rather than a dress chronograph wearing racing colours.

We really look after each other because Team Ikuzawa is very small. It’s just me and two other people in the company. I’m too embarrassed to even call it a company. It’s really a passion project.

Mai Ikuzawa told Hodinkee that community and authenticity drive every project. The dial layout is the clearest proof.

From Tetsu’s Porsche Days to Mai’s Cultural Brand

The founding history of Team Ikuzawa starts with Tetsu Ikuzawa, a pioneering Japanese driver of the 1960s and 1970s. He won the 1964 Japan Grand Prix in a Skyline GT, raced Formula 3 and Formula 2 for Frank Williams, became the first Japanese driver at the Le Mans 24 Hours in 1967, took a class win at the Nürburgring, drove as a Porsche factory pilot and tested for Lotus F1 under Colin Chapman. As a team owner he fielded cars at Le Mans (including Mark Blundell’s famous Nissan pole) and even touched the Isle of Man TT.

1. 1964, Tetsu wins Japan Grand Prix in Skyline GT, sparking the Skyline legend.
2. 1967, First Japanese starter at Le Mans; class victory at Nürburgring 500 km.
3. 1970s-80s, Team Ikuzawa races with distinctive red-and-white colours; Roadmaster stopwatches become pit-lane icons.
4. 2023, First TAG Heuer Carrera collab (42 mm) with Bamford and Mai.
5. 2026, Second chapter on the 39 mm Glassbox platform, 150 pieces.

Mai, now Team Principal and Creative Director (and a creative director at Bentley), shifted the brand from pure racing toward motorsport culture, fashion and design collaborations. The red-and-white codes and stopwatch clarity remain the constants. George Bamford’s department translates those codes into production-ready details without watering them down.

The line from Tetsu’s factory Porsche seat to Mai’s cultural brief is short on paper and long in practice. Racing results built the colours; the Roadmaster timers fixed the graphic rules; the two TAG Heuer chapters put both on a manufacture movement collectors can service through normal channels.

Five Deliberate Departures from the Regular Glassbox

Collectors who already own a standard 39 mm Carrera Glassbox will spot the changes immediately.

• Printed indices instead of applied metal markers for pure stopwatch legibility.
• Running seconds subdial deleted so the Team Ikuzawa logo can sit above the date.
• Full red treatment on hands, chrono seconds, logos and the entire date disc.
• No tachymeter scale; the flange stays a clean black minute track.
• Special caseback engravings, toolbox packaging and two racing straps plus charms.

The movement stays in the same TH20 family, so service and reliability match the open-production pieces. The premium buys the archive-driven dial, the limit and the complete ownership kit.

Because the tachymeter is missing, some buyers may want a refresher on what a tachymeter scale does on classic racing chronographs. Here the designers simply chose stopwatch clarity over average-speed calculation.

None of the five changes alter how the watch is wound, set or timed. They rewrite only what the eye meets first: a white textured field, sponsor space at six, and red accents that match the team’s historic livery rather than a generic sports palette.

Toolbox Packaging and the Full Kit

Delivery is part of the story. Each watch arrives in a mechanics’ toolbox-style case rather than a standard leather box. Inside sit the steel bracelet on the watch, the white perforated leather racing strap, the white textile strap with red stripes, a travel pouch and a set of Team Ikuzawa charms for keys or bags.

150 pieces worldwide, each individually numbered.

USD 10,500 / EUR 10,450 / CHF 9,900 retail.

Three straps total (steel + leather + textile).

Toolbox presentation with travel pouch and charms.

Early reports from Italy already described online stock as gone. At this production level, that speed is unsurprising.

The toolbox format turns unboxing into a small workshop moment. Swapping from steel to the perforated leather or the striped textile changes the watch’s posture without tools beyond a standard spring-bar routine, and the charms extend the team mark beyond the wrist.

The 2023 Collab Steps Down to 39 mm

Three years separate the two Bamford-Ikuzawa Carreras. The first chapter used a 42 mm case. This second release moves onto the 39 mm Glassbox platform that TAG Heuer introduced in 2023 and caps production at 150 individually numbered pieces.

• 2023: first collab, 42 mm, Bamford and Mai.
• 2026: second chapter, 39 mm Glassbox, reference CBS221M.EB0435, 150 watches.

The size cut is more than a trend chase. At 39 mm diameter, roughly 13.9 mm thick and 46 mm lug-to-lug, the new watch shares the open-production Glassbox footprint while carrying the full Roadmaster dial language. Collectors who passed on the larger first edition now get the same red-and-white hierarchy in a tighter steel case.

Mai Ikuzawa and George Bamford used the interval to return to the archives rather than simply shrink the earlier design. Printed indices, deleted running seconds and the pinball minute counter all trace to the 1970s and 1980s stopwatches, not to a scaled logo placement. The smaller platform makes that archive work easier to wear every day.

Scarcity Meets a Clear Historical Line

The price sits roughly 45-60 percent above a regular steel Glassbox chronograph. Buyers pay for the 150-piece limit, the Bamford-Ikuzawa design work, the dual extra straps and the authentic pit-lane graphic language. The TH20-10 remains a modern column-wheel automatic with long power reserve, so daily wear is practical.

For motorsport fans the watch functions as a compact archive piece. The same red-and-white that once marked Tetsu’s cars and the Roadmaster timers now sits under a contemporary glassbox crystal on a manufacture movement. Availability is through TAG Heuer boutiques and the official limited edition product page. Once the 150 are gone, the only route is the secondary market.

That premium is easy to map. Open-production 39 mm Glassbox chronographs list around USD 6,450 to 7,250. The jump to USD 10,500 funds the limited run, the toolbox kit with three straps, and dial work that copies Roadmaster priorities instead of standard Carrera applied markers. Service stays inside the TH20 family either way.

Why the Limit Still Feels Wearable

A 150-piece racing collab can read as a safe queen. This one is built to avoid that fate. Water resistance of 100 metres, an 80-hour reserve and a screw-down crown support regular use. The steel bracelet handles daily rotation; the leather and textile straps cover weekends and travel.

Omitting the tachymeter and the running seconds hand strips away functions many owners never touch. What remains is central chronograph seconds, a 30-minute counter, a 12-hour counter, hours, minutes and date: the same core a pit crew needed from a Roadmaster. The TH20-10’s column wheel and vertical clutch keep pusher action crisp when the chrono is actually started.

Early sell-outs in Italy show demand already outran supply. For buyers who secure one, the practical case and movement mean the archive graphics do not have to live in a drawer.

Frequently Asked Questions

How many TAG Heuer Carrera x Team Ikuzawa watches were made?

Exactly 150 individually numbered pieces worldwide. No further production is planned, which is why early markets already reported sell-outs.

What movement powers the 2026 Team Ikuzawa Carrera?

The manufacture automatic calibre TH20-10 with column wheel, vertical clutch, bidirectional winding, 4 Hz frequency and an 80-hour power reserve. It is chronometer-certified and visible through the sapphire caseback.

Why does this model lack a running seconds hand?

The designers removed it deliberately to free space at six o’clock for the Team Ikuzawa signature, copying the sponsor-space layouts of 1960s and 1970s Heuer racing chronographs and the clarity of the original Roadmaster stopwatches.

What is the case size and water resistance?

39 mm diameter, approximately 13.9 mm thick, 46 mm lug-to-lug, stainless steel with Glassbox domed sapphire crystal. Water resistance is rated to 100 metres.

Which straps come with the watch?

A seven-row stainless steel bracelet is fitted. TAG Heuer also supplies a perforated white leather strap with red stitching and a white textile strap with red stripes that reference the team’s historic racing colours, plus a travel pouch and charms.

How does the price compare with a regular Carrera Glassbox?

The limited edition retails at USD 10,500. Open-production 39 mm Glassbox chronographs typically list between roughly USD 6,450 and 7,250 depending on dial and configuration, so the premium covers the collab design, packaging and 150-piece scarcity.
