Design Concept
The bell rings when the leading runner enters the final lap — signaling the start of the ultimate showdown. This sound, which carries across the stadium, not only heightens the excitement for spectators, but also spurs the athletes to unleash their full power for the final sprint.
In creating this bell, we pursued both functionality — ensuring that the sound is heard clearly by the athletes — and aesthetic beauty (making an object worthy of such a defining moment).
Redesigning for
Performance and Presence
The bell embodies SEIKO’s spirit of precision and the unique quality of this championship. Our Timing and Design teams first analyzed existing bells, then explored how to improve both design and sound quality.
The final design features a smooth, flared edge with subtle Japanese accents. We upgraded the material from brass to bronze for a richer, more resonant tone, and increased the thickness to deliver a clear, lingering sound reminiscent of traditional Japanese bells. We also wanted a design that could stand up to severe weather conditions, so we adjusted the inner shape of the bell based on maritime signal bells. By making it more like a ship’s bell — the kind that is rung in fog or bad weather to prevent collisions — we were able to produce a more powerful sound that resonates clearly regardless of weather conditions.
Applying Watchmaking Expertise
The SEIKO logo is perfectly aligned on the bell’s curved surface thanks to optical correction, a technique used in watch bezels. Three mirror-polished logos contrast with a finely brushed hairline finish on the body, creating a dynamic interplay of textures. These finishing techniques are the same as those found in luxury timepieces.
Crafted with Japanese Tradition
Production was entrusted to Japan’s leading bell manufacturer, the Roji Foundry in Takaoka, Toyama Prefecture. Despite the complexity of the logo, Roji’s expertise with traditional metalworking techniques achieved a flawless finish.
The bell’s cord was made by Ryukobo, a Tokyo atelier preserving Edo braiding traditions since the Edo period. Using the championship’s theme color, Edo Purple, the cord combines purple threads with gold and silver accents to express the elegance of Edo culture.
Its thickness, strength, and length were meticulously tested for comfort and functionality.
