The Wyvern GMT Chronometer has a multi-level dial to accommodate various indications with perfect legibility. Available in blue, silver or black color, the dial is finished with a sunshine pattern.

The dial is comprised of multiple layers. To start with, it has a central circle hosting all the four hands (hour, minute, seconds and GMT). It also has dotted markers placed as a pair of two for representing 12, 3, 6 and 9 respectively.

Immediate to the central part is a 24-hour dial ring for tracking the additional time zone. Surrounding the GMT (24-h) scale is a large dial ring with applied hour markers and minute track for indicating the primary time zone. Bordering the dial is a flange of same color with markings indicating from 5 to 60.
