The sports performance of the Ball Engineer III Starlight includes anti-magnetic protection, to 80,000 a/m, offered by a mu-metal (nickel, iron, copper and molybdenum) shield that encapsulates the movement. The case has a water resistance rating of 100 metres, with a screw-in crown.
The dial comprises 48 tubes on the 40 mm model. The gas tubes are powered by H3 (tritium), producing light that is initially 100 times more intense than SuperLuminova, with a lifetime of at least 25 years. Tritium is a radioactive isotope of hydrogen, H3, with one proton and two neutrons. It has a half life of about 12 years, decaying into Helium-3, releasing a low-energy beta particle, an electron, and an electron antineutrino. This decay process is very low-energy, and the beta particles can penetrate just 6 mm of air. They are unable to penetrate human skin. So the process is absolutely safe for the wearer. In this Ball watch, tritium gas is sealed in a mineral glass tube, whose interior is coated with luminescent material that glows when activated by the electrons released by tritium as it decays. This luminosity is constantly present, though it will gradually decrease over the years, to 50% after 12 years and 25% after 24 years. But even at that stage, the luminosity will be much brighter than SuperLuminova.
This highly collectible custom engraved watch will come with the BOX, tag, international warranty card and A Letter of authentication from the Watch Engraver.
