Surrounding the perimeter is a contrasting angled chapter ring printed with an integrated tachymeter scale, enabling wearers to calculate speed over known distances. Polished hour indices and sporty sword hands are treated with LumiBrite luminescence, ensuring rapid legibility in dim environments, while a discreet date window rests between 4 and 5 o’clock.

Protecting the multi-layered dial is Seiko’s signature Hardlex crystal, providing superior impact resistance for daily wear.
