The Luminox SXC PC Carbon GMT 5020 Space Series was developed specifically for space. The watches from this series were developed in collaboration with SXC (Space Expedition Corporation) and will be worn by the astronauts and passengers of this expedition. They have the unique lighting system from the Swiss company mb-microtec. The H3 tritium lighting guarantees accurate display in all visibility conditions. The power-independent lighting shows the time precisely in all lighting conditions, without battery consumption or charging by sunlight or artificial light, permanently with constant luminosity, without pressing a button. The second time zone is displayed with a separate hand (in yellow, red or blue). The ultralight polycarbonate housing has been reinforced with 30% carbon so that it leaves a good impression in all activities.
