Why does the luminous watch last for a short time.
You must have heard of glow-in-the-dark watches, which can glow at night or in dark places. This feature is what makes glow-in-the-dark watches different from other watches; glow-in-the-dark watches can glow in the dark, making them a cluster for communities such as night travelers or donkey lovers.文章源自复刻手表-https://www.bbtwatch.com/en/wbzs/66051-html

1. What is a luminous watch?文章源自复刻手表-https://www.bbtwatch.com/en/wbzs/66051-html
Luminous watches are watches that glow at night. There are three kinds of luminous watches. The first is photoluminescence, which means that it needs strong light to glow at night. The second kind is electroluminescence, which means that it needs to convert electrical energy into light energy, and the third kind is photoluminescence.文章源自复刻手表-https://www.bbtwatch.com/en/wbzs/66051-html
Nowadays, common glow-in-the-dark powders are caused by sunlight, UV rays and light. When glow-in-the-dark powder is stimulated, it glows. After a minute, the luminous powder is known as the initial brightness, and then the brightness will slowly diminish. The brighter the initial brightness, the longer the glow. The initial brightness is related to the intensity of the light source at the time of stimulation. This is what you call the luminous function of the watch. The longer the luminous time.文章源自复刻手表-https://www.bbtwatch.com/en/wbzs/66051-html
The second type is the electroluminescent powder representing the Barabol Vapor Lamp. The principle of this luminescent powder is to make full use of the electrons released by the decay of water vapor to stimulate the luminescence of the phosphor phosphor.文章源自复刻手表-https://www.bbtwatch.com/en/wbzs/66051-html
The third type is the ray luminescent powder, which represents the vintage watches of Rolex .50.Panerai. Because they use radioluminescent powder to ensure a strong luminescence on the dark ocean floor, they use radioluminescent powder so that the radioluminescent powder can stimulate the light, of course, it still has an effect on the human body.文章源自复刻手表-https://www.bbtwatch.com/en/wbzs/66051-html

Currently, the main material for glow-in-the-dark is tritium. It is much less harmful than radium. Under normal conditions, it is negligible. Generally, the coating on the dial can last 3-5 years. BALL brand is recommended. It has a luminescence that is a gas light that lasts about 20 years, but it is a different color. It seems that the cooler colors last shorter.文章源自复刻手表-https://www.bbtwatch.com/en/wbzs/66051-html
2. How long does the luminous watch stay on?文章源自复刻手表-https://www.bbtwatch.com/en/wbzs/66051-html
Now it's generally a limited first light time and limited brightness as mentioned above, starting brightness is proportional to the intensity of the stimulating light source, i.e., exposure to bright light during the day will be brighter at night, and the longer the exposure, the longer the nighttime luminous time will be.
3. Why doesn't the luminous watch light up?
If watchmakers encounter their luminous watch, which doesn't light up at night, they may not have a light source to energize him. We can try to shine him with a light source first. If not, we can go to the repair store to replace the luminous powder. The above is an introduction to the luminous watch luminous principle of timeliness. At present, the luminous watch is basically replaced by the super luminous coating, which will not oxidize and will not have radioactive danger. So you can rest assured.
