Large dial with large numbers for easy visibility. Encapsulated tritium (Isotope H3) light sources are used at each hour position on the dial and on all hands. There are two tubes at the 12 o’clock position.

Case Back
Space allowance on the back of watch case for personal engraving

Tritium Gas Tube
The JDD uses self-contained tritium gas tubes to ensure constant visibility in low light situations. A tritium gas tube is placed on each hour marker and on all hands. MaraGlo paint is used for the 12-hour bezel marker. Tritium tubes are self-illuminating gas tubes that contain an isotope of hydrogen, meaning they will not dull down in brightness like normal photo-luminescent paint which requires an external light source to create a glow.

The JDD is made in La Chaux de Fonds Switzerland to guarantee the highest level of manufacturing quality and accuracy
