Key Features

Integrated Tachymeter Scale: Unlike a bezel-based tachymeter, the scale is printed directly onto the dial face, creating a distinctive, instrument-like look perfect for chronograph-style or racing watch builds.
Maximum Visibility with Full Lume: The “All luminous” feature means the tachymeter scale, hour markers, and hands will glow uniformly in the dark, offering exceptional legibility and a striking visual effect.
Extremely Broad Movement Compatibility: This dial is engineered to work seamlessly with almost the entire Seiko NH family and its predecessors, providing unparalleled flexibility for modders.
Direct Custom Branding: The option to add a custom logo makes it perfect for creating unique personal watches, branded gifts, or as a base for micro-brand production.
Ready for High-Impact Builds: This dial is designed to be the visual centerpiece of a watch, best paired with bold hands and a case that complements its sporty, technical theme.
