Casio watch luminous hour hands

The old bird is here.

To answer your question first, this is normal. The Casio coating lasts approximately 10 minutes. Some mid-range Swiss watches with good luminous materials (like Panerai) can still be very bright after half an hour and only dim after about an hour. There is a luminous coating that stays in place, but one should be concerned about this type of coating because this type of coating is radioactive and can cause skin cancer. It was mainly used in the 1950s and 1980s. It has since been banned.

Fluorescent coating materials can be divided into two types: self-luminous and light-storing. The type of fluorescent agent that always lights up is called a self-luminous fluorescent agent, which mainly relies on the traces of radioactive substances it carries to release rays to stimulate the fluorescent agent to emit light. This type offluorescent agent, called fluorescent light storage agent, basically does not contain radioactive substances, but it needs to absorb and store enough external light intensity in advance to pass its own electrons from a low energy level at a high energy level and store them. When the environment is dark, it gradually releases the absorbed energy. At this point, the electrons move from a high energy level to a low energy level and the fluorescent agent begins to emit light. Since the light storage type does not contain ray excitation materials, the afterglow persistence is temporarily not as good as the self-illuminating type.

For health reasons, it is best not to use a night light that is too powerful. The old bird is gone, hope this helps.

What type of watch is the Casio g1000p?

If you want to storelight, you need to put it under the light, but if you want to use photodynamic energy, do not put it under strong light to avoid damage to the watch. Sunlight is good. If it still doesn't work, have it checked. Today's watches mainly use phosphorescent watches. Self-illuminating watches are used less and less because the materials used are harmful to the human body and the environment. Here's what I found online, I hope it's helpful to you.

Phosphor powder (commonly known as luminous powder) is generally divided into two categories: photoenergy storage luminous powder and radioactive luminous powder. Photo energy storage luminous powder is a fluorescent powder that stores light energy after being irradiated by natural light, sunlight, ultraviolet light, etc., and slowly releases itin the form of fluorescence after stopping the light irradiation, so it can be used at night or in dark places, you can still see the glow, which lasts from several hours to more than ten hours. The radioactive luminous powder is mixed with radioactive substances in the phosphors, and the rays continuously emitted by the radioactive substances are used to stimulate the phosphors to emit light. This type of luminous powder emits light for a long time, but its application range is limited. such as toxicity and environmental pollution.

The Casio G1000P is a multifunctional digital mechanical hybrid watch. It uses solar panel power and wireless charging technology, so users do not need to frequently replace batteries when wearing it, while reducing usage costs. The Casio G1000P is very rich infunctions including time, date, stopwatch, countdown, alarm clock, flash warning, night light, altimeter, barometric pressure, temperature and compass etc., which makes it makes it convenient for users in various outdoor sports. , travel and other scenarios. In terms of appearance, Casio G1000P adopts a classic aviation dial design and uses a shock-resistant design to make the watch more durable.
