Self-powered micro gas tubes (H₃) are a special light made with smart Swiss laser technology. BALL Watch traps pure tritium gas safely inside a small, strong glass tube. Inside, the tube is coated with a glowing material.
What Is It Made Out Of?
“The interior walls are coated with luminescent material that gives off cold light when activated by the electrons emitted by the tritium, in much the same way a television screen functions.The small, precise, lightweight H₃ gas tubes are efficiently produced by means of a CO2 laser. The tubes are then attached to the hands and dial in a secure manner that precludes any risk of breakage.” by BALLWatchCompanySA
Instead of regular glow paint, BALL uses small glass tubes filled with tritium gas and coated in phosphor powder. The gas gently powers the glow, giving you soft, steady light for up to 25 years. No charging. No sunlight needed. Just quiet, constant brilliance on your wrist. Choose a BALL watch, and always see the time clearly, day or night.
Wearing a BALL watch is always safe. In fact, everyday life gives you more natural radiation than this tiny glowing tube ever could.
This light is perfect for anyone who loves fine watches with real function. Pilots, divers, and travelers love it for true, safe night walk and night reading. It’s also perfect for anyone who simply loves bold, glowing design on their wrist. Every BALL watch owner enjoys this quiet luxury, day and night.
A BALL watch is more than a timepiece. Its self-powered micro gas lights bring quiet brilliance to every hour, in light or in dark. Elegant, dependable, and always glowing — that is the BALL promise.
