What You Want To Know About Watch Luminant
Have you ever thought about what causes your watch to glow in the dark?This subject has a very colorful and dubious history. It started early in the 20th century, around 1910, when some companies began to use radium on watch dials and hands to create a "glow in the dark” effect. Radium is an almost pure white alkaline radioactive earth metal, and is found in nature in uranium ores. It was discovered by Marie and Pierre Curie in 1898. What Marie Curie discovered was that a test tube of radium emitted a "fairy-like glow,"and she kept a vial next to her bedside as a kind of night light. She further discovered that the glow wasn't coming from the radium itself, but from the ionization of the materials surrounding the radium, which when ionized, emit light (glows). The watch companies added materials to the?radium paint which caused the materials to glow, thus lighting up the numbers and hands in the dark.
Taking Timepieces To The Next Level With Artisans De Gen¨¨ve
Sponsored post presented on best watches by advertiserFor centuries, the concept of the wristwatch has evolved and adapted to fit the needs of the environment in which it existed. From the delicate wristlets of royalty to the rugged deep divers of 1960's, watches are as much about expression as they are about function. In modern times, this sentiment has never been more true. Coming across as somewhat contrarian in the digital age, mechanical watches are an extension of personality. They possess the capacity to speak volumes about who we are and what type of person we wish to be. Without waxing too philosophically, wristwatches, for many, are a highly personal memento that bears the weight of sentiment and individualism. Despite the diversity found within the horological market, there are times when the desire for expression transcends the factory configuration. It is in these times where Artisans de Geneve helps make dreams a reality.
