Although luminous is a basic decoration of the watch, but also as a function of the watch, it seems to be relatively dull and boring for us to spend time with the watch. Almost every companion who likes watches will know a little about it. You know, the first modern watch in history has a century of history. In this watch’s history, watches have experienced many evolutions from workmanship to shape, from materials to complex functions. The maturity of each watchmaking technology is closely related to the development and progress of the technology of the times. As the usual luminous function is also commonplace, its technology from development to perfection is intriguing, full of fun and accident. Many watches now have this magical feature, and even more, with its excellent luminous design, it has become the biggest selling point of watches. Want to really know about luminous watches? Follow me! Let’s turn off the lights and look down.
The invention of the first watch full of chance
Breguet, Napoleon’s Choice
When it comes to the luminous function of the watch, we must first understand how the watch comes. The ‘birth’ of the first watch was not from the hands of a professional watchmaker or from the master’s pen, but from the Emperor of Napoleon, the French emperor who could not hit the clock. It is said that in 1806, Napoleon ordered the craftsmen to create a bracelet that could only place the ‘small bell’ on the wrist in order to win the beauty (Queen Josephine). This was the first wristwatch in the world. Pocket watches have since become a symbol of men’s status, while watches have become a small object to show the charm of women.
Radium Luminescence-the first light to read the night timepiece

Since the creation of the watch, the creation of it has never stopped. Maybe someone asks, isn’t the first light luminous powder? Luminous powder is indeed a fluorescent material earlier than radium. This material is a substance powder such as zinc sulfide as a matrix. It does not have the function of emitting light, but only emits light after being illuminated by light. However, due to material and technical issues, such powders can only maintain their light for a short time.

Early pocket watches rarely had this feature, and its popularity was gradually reflected only after the need for military instruments in subsequent wars. At night, the light source at that time was mainly a flashlight or a light bulb, but in a war environment, using these two things to complete night operations is fatal, because the light source will expose your location, and the concealed light source has become an urgent problem to be solved at that time. . Therefore, more than twenty years after Madame Curie invented the radium element, because the extraction technology of radium was relatively mature, the scale and output were greatly improved, and the application of the element gradually moved closer to industry. Radium is a radioactive element that can emit both alpha and gamma rays, so it can produce self-luminescence with a certain brightness after a certain synthesis, which is relatively suitable for making noctilucent materials for close observation. Therefore, the fluorescent coating made of zinc sulfide, radium bromide and neofluoride was mixed with glue and applied to military instruments and watches.

But radium, after all, is a radioactive element, which itself is highly toxic. Even if it is rarely measured and protected by the case and cover, there will still be harm to people. At the time, radium could not be used as a fluorescent agent. Another drawback was that the watch was not tight at that time. The long-term use of the watch caused water vapor and air to enter it, and radium would soon age and lose its effect. However, radium is also very meaningful in the development of fluorescent agents. The famous brand PANERAI named the current series with the Radiomir night light they used that year, indicating that radium night light once affected a considerable area.

Fifty years later, with the development of science and technology, the use of radium has been greatly protected, and it will no longer affect human health due to other materials or workmanship. But at this time, another safer and more practical chemical element ‘氚’ began to be used in various public watches. Because its radiation is small and very practical. It is also one of the modern mainstream phosphors that emits light through the collision of glass tubes.

Self-luminous noctilucent materials (radium and thorium), can continuously emit light without absorbing energy from the outside. The common ‘T & lt; 25’ in the diving watch means that the radiation of radon is less than 25 Curie units, which meets the safety standards. On Swiss watches during the past 50 years, ‘T Swiss Made T’ is often marked below the six o’clock, which means that Luminous uses 氚 as its material, and the dosage meets safety standards. The half-life of radon is approximately 12.5 years, which means that radon can illuminate a watch for more than ten years. After this period of time, the salamander began to age, turn yellow, and gradually lost its luminous effect. Later, Japan invented a tritium compound to delay the aging period of tritium, which allowed the watch’s fluorescence to last for a long time. But after all, as a radioactive element, although the risk does not affect the wearer, it will also affect the production workers of the raw materials, plus the United Nations humanitarian control, so the watch brand at that time used it very little.
It is believed that everyone will not be unfamiliar when it comes to miniature radon tubes. The real name of this miniature radon tube that is popular in the military watch industry is called ‘Tritium Gas Vial’. Since 1989, the US military watch has adopted its standard specification. In 1991, the radon tube army The watch was formally assembled by the U.S. military and was widely used in the first Gulf War.
Luminova safe and stable

Luminova is a non-radiative and environmentally friendly material. It was first developed by Japan’s fundamental special chemical group in the 1980s. Until the mid-1990s, this new type of noctilucent material was put into production. Until now, this luminous material has been used in all corners of the world, from small watches to large precision instruments on airplanes and ships, all use this material to decorate the charming night, making many operations possible Tightly packed at night. Of course, it is also widely used in watches. For example, this watch from Lange made me deeply in love with the luminous performance of the watch. Let us watch it together!

Summary: The glamorous watch luminous function also has its tortuous development path. The seemingly simple technology on the watch has a little-known history behind it. If you like the luminous function of the watch, you need to understand its interesting development history, so that it is the correct attitude to the mechanical craftsmanship in this era of pedestrians. What kind of luminous watch do you like? Let’s say everyone enjoy it together!
