Rikishi Aka — Red

UNDONE approaches mechanical watchmaking with the restraint found in Japanese design: reduce excess, respect process, and let function define form.

Rikishi takes its name from the Japanese word for a sumo wrestler, a symbol of strength shaped through discipline, balance, and ritual. Not raw force, but power that is trained, controlled, and grounded. This philosophy defines the watch from the inside out.

At the center of the dial sits the power reserve indicator, a quiet expression of mechanical balance. As the watch is worn, energy accumulates. As it rests, that energy gradually returns to stillness. Time is not only measured, but managed.

The dial surface reflects this same discipline through layered textures and controlled finishes. Vertical brushing and structured patterns add depth without shine, allowing light to move calmly across the surface. Nothing decorative. Everything intentional.

Powered by the Japanese automatic Timemodule NE57 and visible through an exhibition caseback, Rikishi reveals its mechanics with honesty. Motion is converted into stored energy. No battery. No shortcuts. Built for daily reliability.

Three colors. One discipline.
Rikishi is strength, held steady.
