What is tritium? 

Tritium is an isotope of hydrogen that has two neutrons in its nucleus. It is radioactive and has a half-life of 12.3 years.

Tritium was discovered by Ernest Rutherford, M.L. Oliphant, and Paul Harteck, in 1934. The two scientists bombarded lithium with deuterons (particles made up of one proton and one neutron) and produced tritium as a result.

Tritium emits photons (packets of light energy) that can be used as a source of light in luminous paint or liquid crystal displays (LCDs). It can also be used to make self-powered lighting devices called beta lights. In these devices, tritium is excited by electrons from metals such as iron or copper which causes it to emit visible light at a wavelength of 633 nanometers (nm).

Introduce GTLS Tritium

GTLS Tritium (Gaseous Tritium Light Sources) is an “All-the-time-glowing” light source. Unlike other traditional light sources, GTLS do not need any external battery, charging of light or maintenance, they are guaranteed to glow up all the time. They are 100 times brighter than other sources comparable in watches.

The radioactivity of tritium will be halved after 12.5 years. The brightness of GTLS, however, drops around 10-15% per year. The life of a GTLS can therefore be as long as 25 years!

GTLS Tritium is a tiny glass vessel filled with Tritium gas, while the inner layer of the glass vessel is coated with a very thin layer of Phosphorescent powder. Tritium gas filled inside is a weak radioactive source. Tritium will continuously generate low-energy Beta particles (electrons) during decay, these particles will energize the Phosphorescent powder which grants it the ability to glow up all the time.

Why use the tritium on the watch

Tritium is used on watches for several reasons. It is a radioactive isotope of hydrogen that emits a low level of radiation, which allows it to be used as a self-powered illumination source. This means that tritium-powered watches do not need a battery or any external source of light in order to glow in the dark, making them highly convenient and reliable. Additionally, tritium is relatively safe and does not pose a significant health risk to the user, as the level of radiation it emits is very low. Overall, tritium is a useful and practical material for use in watches, as it allows for easy, reliable, and self-powered illumination.

Tritium watch VS Luminova watch 

Tritium and Luminova are both materials that are used to create self-powered illumination sources for watches and other devices. The main difference between the two is the way they produce light. Tritium is a radioactive isotope of hydrogen that emits a low level of radiation, which allows it to be used as a self-powered illumination source. This means that tritium-powered watches do not need a battery or any external source of light in order to glow in the dark. Luminova, on the other hand, is a photoluminescent material that absorbs light and then emits it slowly over time, creating a "glow" effect. This means that Luminova-powered watches need to be exposed to light in order to charge up and be able to glow in the dark.

Overall, tritium and Luminova are both effective materials for creating self-powered illumination sources for watches, but they work in different ways. Tritium-powered watches are always ready to glow and do not need to be charged up, while Luminova-powered watches require exposure to light in order to charge up and glow in the dark. Some people prefer tritium watches for their convenience and reliability, while others prefer Luminova watches for their ability to be "recharged" by exposing them to light.

Ultimately, the decision of whether to buy a tritium watch is up to you and what you value in a watch.

Are watches with tritium safe?

Yes, watches with tritium are generally safe to use. Tritium is a radioactive isotope of hydrogen that emits a low level of radiation, which allows it to be used as a self-powered illumination source for watches and other devices. The radiation emitted by tritium is not strong enough to pose a significant health risk to the user. In fact, the amount of radiation emitted by a tritium-powered watch is much lower than the amount of natural background radiation that a person is exposed to every day from sources such as the sun and the earth. As with any radioactive material, it is important to handle tritium-powered watches carefully and according to the manufacturer's instructions in order to minimize any potential risks. Overall, watches with tritium are considered safe to use.

How long will a tritium watch last?

Tritium watches are designed to be long-lasting and reliable, but the exact lifespan of a tritium watch can vary depending on several factors. Tritium is a radioactive isotope of hydrogen that emits a low level of radiation, which allows it to be used as a self-powered illumination source for watches and other devices. The radiation emitted by tritium causes the tritium gas inside the watch to fluoresce, producing a glowing effect. The amount of radiation emitted by tritium decreases over time, which means that the brightness of the tritium glow will gradually fade over time. However, the half-life of tritium is relatively long, at about 12.3 years, so the glow from a tritium watch will remain visible for many years.

In general, a tritium watch can last for several years without needing to be replaced. However, the lifespan of a tritium watch can be affected by several factors, such as the quality of the tritium illumination system, the overall durability of the watch, and how the watch is used and cared for. If a tritium watch is well-made and well-maintained, it can last for a long time and provide reliable, self-powered illumination.

What is the full life of tritium?

The full life of tritium, also known as hydrogen-3, is the total amount of time it takes for the radioactive isotope to decay completely. Tritium is a radioactive isotope of hydrogen that emits a low level of radiation, which allows it to be used as a self-powered illumination source for watches and other devices. The radiation emitted by tritium causes the tritium gas inside the watch to fluoresce, producing a glowing effect. However, the radiation emitted by tritium decreases over time, causing the tritium glow to gradually fade.

The full life of tritium is 12.3 years. This means that, over the course of 12.3 years, all of the tritium atoms in a given sample will decay and lose their radioactivity. The half-life of tritium is also 12.3 years, which means that after 12.3 years, half of the tritium atoms in a sample will have decayed and lost their radioactivity. After 24.6 years, 75% of the tritium atoms will have decayed, and so on. The full life of tritium is the time it takes for all of the tritium atoms in a sample to decay completely and lose their radioactivity.
