How long will the luminous parts of the dial and hands be visible for at night?
A In the early days of watch making radio-active radium and then tritium where used by some manufacturers on dials and hands. This is now a thing of the past. CX Swiss Military Watch prides itself on the fact that they have never used any radio-active materials in their products. The luminous material used by CX Swiss Military Watch is Super-Luminova and, as it is not radio-active, needs activation by being exposed to bright light for an extended period of time. The luminosity thus achieved will last, although with a decreasing intensity, for up to 8 hours.
