Dial
The dial of the Marathon Pilot's Chronograph shows 12 hour and 24 hour time, Date and Day. Chronograph timing is dual graduated, inner graduations are 1/5 sec and as well as decimal 1/100 minute timing (alternate inner timing ring). A sweep central seconds hand indicates 1/5 sec up to 60 seconds; Chronograph sub-registers measure up to 30 minutes and 12 hours each. Register indexes & hands use MaraGlo™paint for low light viewing. Encapsulated tritium (Isotope H3) light sources are used for dial at each hour position as well as the Minute and Hour hands, activity between 28-30 millicuries (under 30 millicuries).

Dial Markings
To make sure that the time can be constantly read (even in low light situations), the CSAR has self-contained Tritium gas tubes place on each hour marking as well as on the minute and hour hands. MaraGlo photo-luminescent paint is used for the 12-hour bezel marker as well as on the minute and hour chronograph register indexes. Tritium tubes are self-illuminating gas tubes that contain an isotope of hydrogen, meaning they will not lose brightness over time like photo-luminescent paint which requires an external light source to create a glow.
