The birth of luminous watches was influenced by military operations. Because the early military instruments, including military watches, had no luminous material to emit light, it was difficult to tell the time in a dark environment, but it was very dangerous to use a strong light source such as a flashlight to expose the position easily. In this case, luminous paint and luminous watch were born. Early luminous watches were harmful to the body because the luminous materials on them used radioactive substances. However, with the development of science and technology, after many times of research, development, and improvement, the current luminous watches basically use materials that do not affect human health.
"Luminous watch" refers to a watch whose hands or nails are coated with fluorescent powder, and the hands or nails can be seen to glow in the dark. Wearing a luminous watch in a dark environment, you can see the time through the night vision material on the dial, especially for many people who have to work in a dark environment, a luminous watch is an indispensable partner for them.
The luminous material of the watch is divided into two types: self-illuminating and light-storing. The basic components of self-luminous luminous materials are radioactive materials, which do not need to absorb energy from the outside and can continue to emit light, not only at night but also during the day.
Light-storing luminous materials rarely contain radioactive substances, and there are no restrictions on use. Still, they need to absorb external light energy to emit light, and they must store enough light energy to ensure that they will always glow. Another defect of light-storing luminous materials is that the brightness is not enough.
The luminous elements of most watches are painted with tritium. Tritium-triple hydrogen (3H), is an isotope of hydrogen, its radiation is b-line, which can be absorbed by metal and glass, but it will penetrate the plastic case, so the previous watch will warn the user not to wear it if the glass is broken.
The luminous amount of the watch is strictly controlled within a safe range, so you can wear the watch with peace of mind. We are a watch manufacturer, capable of OEM and ODM watches, if you need them, please contact us.
