![]() ![]() Its dangerous stuff and one little spec getting inside the body can cause big health issues. His advise is leave the watch cased, its no big problem all the while the dial is behind the glass. it has a half life of 1,600 years, and produces Alpha, Beta and Gamma rays. If you do ingest any, go down the pub and drink 10 pints of beer, Tritium mixes/binds with water, so you'll pee it out. Don't put your nose to the dial and inhale deeply, And don't lick the dial. Make sure you don't ingest any of the lume, I.E accidently getting it on your fingers then eating your cheese sandwich, best to use gloves. His advice when working on Tritium dials is, It has a half life of 12.3 years so old dials pose little threat. Its also too weak to penetrate the skin of the human body. Tritium emits low energy beta radiation, its so low energy the beta rays can only travel 6mm through air before they lose their ionising ability. I'm no nuclear physicist, but my brother is, and I have asked him this question before. The person who wrote the post (ArkJasdain) is a moderator and respected watchmaker on the site. I also found this reddit thread on the problems with removing radium. As tritium has a half life of 12.3 years any radiation it had will be mostly depleted by now, and in any case it doesn't decay into dangerous substances like radium.Tritium is a gas and was combined with zinc sulphide to extend the glow period (zinc sulphide on its own glows for about an hour) of lume during the fifties, sixties, seventies an eighties but was superseded by zinc sulphide combined with rare earth metals (brands such as luminova etc) which contain no harmful radioactive products.In high enough concentrations this is a real health hazard. One of the by products of radium decay is the radioactive gas Radon.Ones that were Radium dialled usually had the letter "R" denoting radium somewhere on the dial.As some of the previous posts in this thread highlight there are other newer Seiko watches out there with Radium dials. The only Seikos that he understands to have radium lume on the dial were 2nd world war era military ones.Ambient dose equivalent rates have been measured for fifteen pocket. I have put his response in bullet form and added a couple details. Abstract: This study re-examines the risk to health from radium (226Ra) dial watches. Here are his main points regarding Radium and Tritium. I shot Duncan (watchmaker) an email and he gave a great reply. The Old Radium is offered exclusively online at £900 (ex VAT).Hi guys. Be careful if you have an older watch with the original luminous compound. Tritium is also radioactive, but its radiation can’t penetrate the skin. ![]() So during the 1960s, all watch manufacturers switched to other materials such as tritium. ![]() Water resistant to 10 ATM, the Isotope Old Radium Bronze Tobacco is a Limited edition of 100 numbered watches, and is available for Free Express shipping via DHL and Royal Mail. Unfortunately, radium is radioactive and therefore dangerous to handle. ![]() Powered by the Landeron calibre 24, the rugged movements acts as a perfect engine for the Pilot’s watch and features a power reserve of 40 hours. To prevent this, the ‘Old Radium’ features a titanium case back. The dial is protected by a sapphire crystal which has an anti-reflective coating and while bronze cases add character to a watch, this unique alloy can also cause allergic reactions when worn directly on the skin for extended periods. The area surrounding the lacrima is in Tobacco Brown exclusive to this Limited Edition of 100 watches.Īrabic numerals, as well as the sword hands, are filled in with Super LumiNova in a colour that is reminiscent of the aged Radium of vintage watches, hence its name ‘Old Radium.’ This is also placed slightly higher so that there is quite a bit of depth to the dial. It features Isotope’s hallmark lacrima in Military Olive, and offers a grainy finish just like the area surrounding it. The dial is highly legible, as one would expect from a Pilot’s watch. ![]()
