Custom Casio F-91w Digital Watch - Vintage Racing Edition Daijiro Kato

Before modern electronics and traction control, there was the GP500 series. This was the era of the 500cc two-stroke monsters—bikes that demanded everything from the world’s greatest champions. It’s the ultimate expression of man and machine at the absolute limit.

This custom F-91W collection is a TRIBUTE to that legendary era. We’ve channeled the iconic racing liveries, the smell of premix, and the bold, high-contrast aesthetics of the track directly onto the watch face. It’s a piece of mission-critical gear for those who appreciate the grit and glory of vintage Grand Prix racing.

74 Forever. The Genius of Precision. 

Daijiro Kato was a phenomenon. Known for his incredible smoothness and absolute dominance in the 250cc class before stepping up to the premier category, he remains one of Japan’s most beloved racing sons. This custom F-91W honors the legendary #74 and the vibrant, high-energy aesthetic of his career.

Featuring the iconic "eyes" motif and the bold racing colors he made famous, this watch is a tribute to a talent that was as bright as it was brief. It’s a piece for those who celebrate the art of the perfect lap and the legacy of a true champion.
