In the sound of the engines, the thrilling moments are played between the high-speed wheels on the racing track. Motorsport symbolizes passion, adventure and a little heroism, and decides which hero to cheer for The standard is speed. The measurement of speed is also a kind of calculation of time. In addition to high-performance racing cars, motor sports also require high-precision chronograph watches. The two types of machinery together perform the wonderful 300 + km / h.

In summary: Some people say that the increasingly perfect performance of racing cars has made racing drivers lose a little personal charm, and the original heroic complex has gradually decreased. In motorsport, the performance of the car can be less perfect, and if there are regrets, the driver can make up for it. But watches don’t work. They must be precise about time and precise in measuring speed.

When playing antique di, I often encounter the luminous part that has passed away, but I still love the yellowed uniform scale on the dial. How has this magical luminous substance evolved to this day? Let me summarize. –Mr. Ye, after the aging of the luminous paint on the antique disc on June 20, 2019, the daytime will appear a yellow 1910, Radium Ra around 1910, because the Radium ra In terms of cost and output, it already has the conditions for industrial mass production, coupled with the demand for war, so it will soon be popularized in military instruments and watches. The radioactive Radium radium luminous paint has its advantages. The half-life of 1600 determines that it will not easily age as long as it does not touch water. But the hidden danger of this material is also very obvious-radioactive. Although the watch contains less radium and is covered by glass, there are risks associated with prolonged contact. Here, there is one more point to be noted, because the waterproofness of antique watches is not very good, so the original luminous paint made of radium made in the modern world is very small. In 1949, Tritium 氚 was extremely restricted in the civilian market after being popular for some time due to its extremely radioactive nature. In its place, tritium (3H)-Tritium 氚. Similar to radium, it can emit light without absorbing energy from the outside, but its radiation is much smaller than radium, and it is naturally much safer in use. The only problem is that the half-life of plutonium is only 12.5 years. Therefore, a watch with 氚 as a luminous paint, after more than ten years of use, the time scale will gradually turn yellow until it loses luminous. This is also the reason why antique Lau Yeguang will discolor or even lose color. Antique Rolex’s luminous paint gradually aged. In January 1949, Panerai produced luminous paint under the trademark Luminor on the base of plutonium. Since then, it has unveiled its supremacy in the watch and luminous field for nearly 50 years. There are two main ways of labeling the disk, one is ‘T Swiss Made T’, which means that the amount of radon used meets safety standards; the other is ‘T <25', which represents less than 25 curie units of radon radiation. In 1993, Luminova. In 1993, Luminova, a new kind of luminous material, was born. It originated from Radical Specialty Chemicals Co., Ltd. and consisted of inorganic aluminate and other elements. Compared with the previous radium or thorium, on the one hand, the luminescence mechanism is different, because the material does not have any radioactivity, so it is not self-luminous, but requires photoluminescence to cause luminescence; on the other hand, it has excellent chemical stability. It is not prone to aging during its life. In 2000, Super-Luminova In 1998, Swiss RC TRITEC Ltd. and Japan's Nemoto & Co. Ltd. established a joint venture LumiNova AG Switzerland, and in 2000 launched an enhanced version of Luminova-Super-Luminova, which is also today Luminous paint widely used by the brand. Compared with previous generations of luminous materials, Super-Luminova has the following three major advantages: ① The luminous color is richer. In addition to green and blue, it has not only white, yellow, and purple, but also special colors can be modulated by mixing various colors. . Among them, the colors are distinguished by the code of 'C + Arabic numerals'. For example, C1 = white, C3 = yellow, C7 = green … ②The main component of non-radiation Super-Luminova is strontium aluminate, which is not a radioactive substance, so it cannot emit light by itself, and it needs a stage for energy storage. It is reported that 10 to 20 minutes of irradiation can continue to glow in the dark for 8 to 10 hours. ③The color is constant for a long time. The color and brightness of the night light of Super-Luminova theoretically will not age with the passage of time. In other words, when the watch is bought, it is blue night light. Rolex ChromalightSuper-Luminova is the mainstream of the current watch market, but it is by no means the only. For example, Rolex has been using DEEPSEA since 2008, which is Chromalight luminous material (phosphorescent powder, blended into liquid resin, and then applied to luminous display parts). The blue light is very dazzling in the dark environment, exceeding the standard of the watch industry. In the patent of Powell, the world's first noctilucent micro-painted enamel leaves accompanied Super-LumiNova to remind them of its current popularity. HYT, which is famous for its creativity, launched the unique light-emitting motor in the watch industry in 2015. After starting through the crown at 4:30 on the case, the generator in the movement will convert the mechanical energy into electrical energy to light up the included LED lights. Under the illumination of this light source, the transparent composite dial loaded with fluorescent nanoparticles absorbs light energy and starts to emit light. Just like the H4 Neo introduced in 2017, it is usually transparent. Once activated, it constitutes a dazzling scene like purple neon lights. | Psalm 119: 105 | Your words are a lamp under my feet, a light on my way. Ta parole est une lampe a mes pieds, Et une lumiere sur mon sentier .
