Three dial colors are available – silver, black and and slate gray with a lamé hand finish. This is an updated version of a technique for creating a densely textured vertical-brushed pattern.

Sword-shaped hands pass over broad, faceted hour markers. Each is treated with Super-Luminova for excellent visibility in all light. The small counter hands are faceted for easy reading. The deep red chronograph sweep-seconds hand bears the Zenith star emblem, and the inscription “36,000 VpH” is painted in crimson red in the upper part of the dial. The tachometric scale appears on the inner bezel ring.
