October 24, 1965 — the historic day when the RA272 delivered Honda’s first-ever Formula 1 victory at the Mexican Grand Prix. Celebrate this very special 60th anniversary with an EDIFICE-Honda collaboration that pays tribute to this legendary achievement. The EDIFICE design team worked closely with Honda, studying every detail of the RA272, the racing legend that sped to victory in the 1965 Mexican Grand Prix, to capture the spirit and engineering of this iconic car. Painted in authentic Championship White, the bezel takes on the exact color of the RA272, marking the first time the car’s distinctive hue has been applied to a watch exterior. The dial features the number “60” engraved in gold tones at the 60-minute mark to honor the anniversary of this historic victory, and the dial ring in red expresses the Hinomaru design painted on the body of the RA272. Each design detail tells its own story. The back of the short side of the leather band is engraved with the exact date and time of Honda’s first-ever Formula 1 win. The band loop carries the immortal words of team leader Yoshio Nakamura: Veni, Vidi, Vici — “I came, I saw, I conquered.” The long side of the band features RA272 engine specifications and original technical drawings. And the case back proudly displays the official logo commemorating this Honda triumph. A meaningful celebration, but also constructed with advanced technologies and equipped with smart features for outstanding functionality. The case integrates carbon fiber-reinforced resin with stainless steel for strength and durability. With scratch-resistant sapphire crystal, 10-bar water resistance, and Tough Solar charging, you’re always ready to go. And it’s a snap to sync with your smartphone via Bluetooth® to get automatically adjusted precision timekeeping, effortless world time, and more. Created for Honda fans across the globe, this special edition watch brings the legacy of Honda F1 and its spirit of innovation right to your wrist.

60 years since Honda’s first F1 victory

The year 2025 marks the 60th anniversary of Honda’s first F1 victory. On October 24, 1965, in the season’s final round at the Mexican Grand Prix, the RA272 — a car entirely developed by Honda, with both engine and chassis built in-house — took the checkered flag. Since that historic moment, Honda has earned six Constructors’ titles and produced four world champions. With an exceptional racing spirit, the name Honda has been firmly engraved in the annals of F1 history.

Authentic Championship White applied to the bezel ring for the first time

The body of the RA272, the first F1 winning car by Honda, was painted in Championship White, a traditional color that continues to symbolize the Honda racing spirit. This same authentic paint has been applied to the bezel ring. After ensuring strong adhesion of the paint to the base layer, a topcoat is added to create the distinctive ivory tone and a glossy finish reminiscent of the car itself, offering a tangible connection to the original car. The number “60” is engraved in gold tones at the 60-minute mark to commemorate the anniversary of the first F1 victory.

Hinomaru design evoking the RA272 body

Against the predominantly white appearance, a vivid red circle around the outer edge of the dial creates a striking presence. This symbolic color scheme, highlighting the contrast of white and red, expresses the Hinomaru design painted on the body of the RA272.

Memorial engraving capturing the moment of the first victory

The message sent from the venue to headquarters — Veni, Vidi, Vici. (“I came, I saw, I conquered”) — is engraved together with the car number “11” on the gold-colored metal band loop.

1.5-liter V12 engine: A pinnacle of Honda technology

The watch band features an engraved blueprint of Honda’s pioneering 1.5‑liter V12 engine — a tribute to the bold, unconventional choice of a 12-cylinder layout at the time. This remarkable engine represented an integration of Honda’s advanced motorcycle technology and innovative thinking, applying 125cc-per-cylinder performance to the realm of four-wheel drives. The band pairs Nappa leather on the outer surface with Ultrasuede on the lining.

The tachometer, which stood out at the center of the RA272 instrument panel, is rendered in the 9 o’clock inset dial and serves as a countdown timer. The design reflects the atmosphere of the original, with careful attention to the color and shape of the analog hand, the font of the scale markings, and the red line indicating the red zone.
