Davosa Argonautic Lumis Automatic

Absolute reliability and functionality are further characteristics of the iconic diving watch from the Swiss manufacturer DAVOSA.

So-called gaseous tritium light sources or GTLS (Gaseous Tritium Light Sources) are located on the numerals and hands of the 
Argonautic Lumis. They are not only particularly safe, but also guarantee the watch user at least
fifteen years of constant brightness - without any external power source.

Furthermore, they glow green in the dark, which is particularly well perceived by the human eye 
in poor lighting conditions.
