How Long Does Tritium Last in Watches?


Tritium is a radioactive isotope that emits beta particles (electrons). These electrons are easily absorbed by most materials, including metals.


Tritium is a radioactive isotope of hydrogen used as a source of energy in many low-power electronic devices, such as flashlights, calculators, wristwatches, pocket and portable bar-code scanners, laser pointers, and radio frequency identification (RFID) tags. Because of its relative scarcity, the cost of tritium can make it an important consideration for manufacturers seeking to produce low-cost items. When discussing the properties of tritium, however, care must be taken to distinguish between tritium decay and tritium's decay time. The former is the half-life of tritium, which measures the amount of time it takes for half of a given quantity of tritium to decay. The latter is the decay time of tritium, which is a measurement of the average number of years a given quantity of tritium will emit one photon of radiation.

The last question you should be asking when you're looking for a watch is "How long does tritium last in watches?" If you're a watch collector, you should know the answer to this question. Because once you do, you can tell what kind of watchmaker created your favorite timepiece. But do you know how long tritium lasts in a watch? And does it make a difference in the quality or longevity of your watch?


The average person uses their watch only once a week or so. That means that most of the time it just sits on the counter and collects dust. But a tritium-powered watch has a life span of many years!

In the case of the Aquatico tritium watch, tritium lasts for at least 24 years, or until the date changes. 


1. What is Tritium?

Tritium is an isotope of hydrogen, with one proton and two neutrons.. Tritium emits a faint glow when exposed to ultraviolet light.

You may have heard of tritium as a possible cause for “battery issues” in electric vehicles like the Tesla Model S. But what is tritium exactly, and why is it such a big deal? Tritium is a radioactive isotope of hydrogen (Hydrogen’s chemical symbol is H). Tritium is used in the batteries of these vehicles because it produces less heat than regular hydrogen, which means the battery lasts longer. It’s also much easier to store and transport because it doesn’t require any special handling. Because tritium is highly unstable, the only way it can be used is if it’s combined with another element, like Lithium, which itself is a rare

This element is very small but very powerful. Because of its extremely low atomic weight (tritium weighs about 12.5 times lighter than lead) it packs a surprising punch. Tritium emits gamma radiation and has a half-life of 12 years. So if you had tritium to give off, it would still be giving off its radiation after 12 years. And what could you use this for? Well, if you needed to create something that could stay alive for a long time, tritium might be your ticket. Tritium lights are found in many things, such as night-lights, flashlights, and the glow sticks you see at rock concerts and theme parks.


2. Where does Tritium come from?

You may have heard of tungsten. It’s used to produce many everyday products including light bulbs. But did you know that there’s also a radioactive isotope of tungsten called tritium? While tritium is not considered a hazardous material, its short half life means it is very dangerous to humans. So the only thing worse than breathing in too much tritium would be swallowing it.

Tritium is the rarest isotope of hydrogen. It’s only found in very small amounts in the earth’s crust, and it’s most abundant in two places: the oceans and the surface of the moon. The next most abundant isotope of hydrogen is called deuterium. The thing that makes tritium rare is that it takes a lot of energy to make it.

Tritium, or tritium, is a radioactive element. Tritium is used in lighting because of its longer life than ordinary light bulbs. It also emits only a small amount of visible light. There are two types of tritium. One is radioactive (unstable) and the other is stable. It doesn't matter which one you use, but the stable form requires special handling in order to store it.


3. What’s Tritium in an Aquatico watch?

Tritium is a radioactive isotope of hydrogen. It was used in watches because it emits a faint glow, which is detectable in the dark. 


4. How long does Tritium last in a Aquatico dive watch?

This is the question many people ask if they are concerned about the safety of diving. While Tritium itself has a half-life of 24 years, the radioactive isotope Thoriated Helium (helium-3) is composed of decays very quickly and has a half-life of only 22 minutes. Half life is the time it takes for half of the substance to decay and in this case, that means half of the Thoriated Helium will decay in just under 22 minutes.


5. How do I measure the amount of Tritium in a watch?

The amount of tritium in a watch can vary widely from the amount needed to keep it in operation. The amount of tritium in a watch will depend on the amount of time it spends exposed to cosmic radiation, such as when it’s inside the earth’s atmosphere. This means that if a person is traveling through space, they’ll be exposed to even more radiation than someone who stays on Earth. The tritium level in a watch is measured in picocuries, with one picocurie being equal to 3 x 10E-12 Cs (where E is energy per particle). To convert from picocuries to nanocuries, divide by 1 million.

Before we dive into the calculations, there’s one thing you should know up front: Tritium, like all radioactive materials, decays over time, and the amount of tritium that you start with can affect the amount of tritium that remains after a certain period of time. This is why the maximum lifetime rating is included with every timepiece. As a result, it’s very important to know how much tritium is in your Tritanium watch, and how long you plan to keep it.



In conclusion,

Tritium is a naturally occurring isotope of helium with a half-life of 12 years. This means that half of the atoms of tritium will decay and emit high-energy beta particles every 12 years, which is why they are so useful as a reliable radiation source. If you’re looking to buy a tritium watch, Aquatico TRITIUM WATCH is the best option.
