10 Tritium Watches

Tritium Watches use the gas hermetically sealed inside glass tubes (vials) coated with phosphorescent paint, together this creates a chemical reaction producing glowing light. Tritium has a half life of 12.3 years so its brightness will start to fade after that and most manufacturers give the tritium illumination a longevity of between 10-20 years.

radiation 10 Tritium WatchesMen in orange suits carrying geiger counters come to mind at the mention of radioactivity, however the radioactive gas Tritium is harmless at the amounts used in tritium watches.

Tritium is a naturally found Hydrogen atom with an atomic weight of 3, so its symbol is H3. In watches the gas is hermetically sealed inside glass tubes (vials) coated with phosphorescent paint, together this creates a chemical reaction producing colourful glowing light.

Tritium has a half life of 12.3 years so its brightness will start to fade after that and most manufacturers give the tritium illumination a longevity of between 10-20 years. After that the watch needs to be sent back to the manufacturer to have the Tritium vials replaced. Mb Microtec is the main supplier for tritium in watches.

Despite many watch manufacturers claims with their sales hyperbole, Tritium is not the brightest form of watch illumination, Superluminova is brighter.

However the advantage Tritium watches have is that tritium doesn’t require any ambient light source to charge itself and will glow consistently at the same constant level providing unlimited night time readability.

Whereas Super-Luminova or other phosphorescent luminescent paint initially glows brighter but tapers off, progressively becoming less luminous over several hours.

Tritium watches are useful for people who work for long periods in dark environments, for night diving or for people who just like the novelty of owning a watch that is constantly illuminated.

Reactortritium watch

Reactor developed a special proprietary way of applying Superluminova for their watches, which according to independent tests made them the “longest-lasting phosphorescent watches in the world “.

However while Superluminova is up to five times brighter than Tritium it fades to below the level of Tritium after several hours.

So Reactor decided to develop a special technology for their Tritium watches called Never Dark which combines the Swiss phosphorescent paint Superluminova with Tritium-filled tubes for the benefits of both.
