Q: How long does tritium illumination last in watches?
A: Tritium illumination maintains useful brightness for as long as 25 years depending on the colour of the phosphors used and the amount of tritium contained inside the tube. The technology provides clearly visible illumination throughout this period, far exceeding the life span and performance of any other luminous technology in the market today.

Q: Is it safe to wear a tritium watch every day?
A: Yes, tritium watches are completely safe for daily wear. The energy emitted cannot penetrate human skin or watch crystal. Exposure levels remain far below natural background sources you encounter daily.

Q: What's the difference between T25 and T100 tritium ratings?
A: T25 tritium provides controlled illumination suitable for tactical applications requiring discretion. T100 creates maximum brightness for challenging visibility conditions. Both ratings ensure completely safe daily wear.

Q: Why does tritium cost more than traditional luminous watches?
A: Tritium requires highly specialised manufacturing, premium Swiss production facilities, and regulatory compliance. The sealed tube construction and meticulous quality control is a very laborious and expensive processes but results in many years of reliable performance.

Q: Do tritium watches work underwater or in extreme conditions?
A: Tritium illumination operates independently of environmental conditions. The sealed tube system remains unaffected by water, temperature, or pressure, making tritium ideal for diving or extreme environments traditional luminous technology fails.
