Decrypting The Classic Watch Technology Of 5 Major Watch Brands

Numerous great inventions and craftsmanship have been born in hundreds of years of watchmaking history. Luminous technology is arguably the most interesting example among them. Luminous is just a decoration on the dial, but it is very important for watches. In theory, the practicality of the little luminous watch is actually comparable to the super complicated technology. Especially for diving watches, the luminous function can be said to be necessary. Essential.
Blue light Yingying-Rolex
Noctilucent technology: Chromalight

 Rolex’s luminous dial shows that Chromalight, an innovative fluorescent material, is used. The so-called ‘Chroma’ is ‘color, saturation’. This material emits blue light and is used on a series of Rolex professional oyster watches hands and clocks. Compared with general standard fluorescent materials, Chromalight’s luminous time is almost doubled. Its luminous intensity is more stable during a complete dive and lasts more than 8 hours. In 2008, Rolex used the Chromalight fluorescent material for the first time on its Oyster Perpetual DEEPSEA, a diver’s professional watch with a waterproof depth of 3900 meters. It is the blue color of the Rolex diving watch.
Rolex Submariner Series 114060

 This is a new Rolex model from 2012. As a model for diving watches, the new submariner model continues its extraordinary tradition with a redesigned exquisite case, Cerachrom bezel and representative strap of the New World. On the black surface, the hour markers and hands are enlarged, and the chromalight luminous material emitting blue light is coated, which greatly improves the legibility of the watch in the dark. Water resistant to 300 meters.
Noctilucent patent holders-Panerai
Luminous technology: Radiomir, Luminor

 Panerai is an old brand, established since 1860, and one of the three patents it prides itself on is left to the luminous technology-Radiomir.
The reason why Panerai’s technology is called Radiomir is because the radioluminescent material used is radium radium. Radium is a pure white alkaline earth metal that is oxidized to black when exposed to air. All compounds of radium are radioactive. Radium’s Latin name means radioactive. The nature of radium is not stable. It will decay into plutonium in about 1600. Because of continuous decay, it will emit light blue light.
In 1949, another important luminous technology of Panerai, Luminor, also applied for a patent, which used another radioactive material, plutonium, as a luminescent material. This technique is more secure, but still has time constraints.
Both radium and radon are self-luminous luminous materials, and do not need to absorb energy from the outside to continue to emit light. The half-life of plutonium is 12.5 years, that is, the effective life of luminous light produced by plutonium is about ten years. After more than ten years, the cormorant began to age, turn yellow, and gradually lost the luminous effect.
Most current watches use materials with longer afterglow, such as the current mainstream Super-LumiNova, which only needs to be exposed for 30 minutes and can continue to emit green light for 8 hours. This material appeared in the 1980s. Its main component is strontium aluminate. After adding rare-earth thorium, it can emit light for several hours as long as it is exposed to light for several minutes.
Panerai PAM 00382

 This very heavy-taste bronze watch from Panerai, numbered PAM382, uses a fully-automatic P9000 self-winding movement with hours, minutes and seconds. The watch diameter reaches 47mm, which is a true pure man watch. The bezel, case, lugs, and unique crown are all made of bronze and have been crafted to make it unique. Water resistant to 300 meters and Luminor technology.
German innovation-Lange
Noctilucent technology: UV excited phosphor phosphor emits light

 All roads lead to Rome. There are always different ways to solve the same technical problem. The realization of noctilucent is the same. A few cases that have been painstakingly devoted to the luminous body have been introduced before. Now look at the individual ingenuity-the luminous effect is achieved through the dial. This is to mention the German patent DE102010000749 of Lange, filed on January 8, 2010, and inventor WENZELJAN. This design is applied to Lange’s famous ‘owl’ ZEITWERK luminous version.

 Lange’s luminous design, the dial is made of sapphire, and then coated on sapphire. The coating consists of two layers. The first layer is a metallic silver coating and the second layer is a titanium oxide coating. 100 nanometers. This design has only one purpose. It does not transmit visible light and only transmits ultraviolet light. The phosphorous phosphor is excited by the transmitted ultraviolet light to emit light. The choice of titanium oxide and silver coating materials and the thickness design are such that the transmitted ultraviolet light has a wavelength between 250 nm and 430 nm, which can maximize the phosphor phosphor to emit light.
After comparing many designs, I feel that German technological innovation is indeed quite special. For example, the design of the automatic winding efficiency introduced earlier, only the Germans thought that the reduction ratio of the two-way winding was designed to be different, so that the mainspring could win Tighter.
Luminous Sticky-Blancpain
Luminous technology: Luminous scale bonding

夜 Now that luminous technology is so mature, how to present this technology has become the focus of attention of various brands. In 1997, Blancpain produced the Fifty Fathoms watch with a water resistance of 300 meters. In 2003, in order to commemorate this legendary watch model, Blancpain specially launched a new limited edition watch, this watch has a black arc-shaped scratch-resistant sapphire crystal bezel, and different materials, different hardness This kind of professional technology, which is combined with different heated rigid bezels, fluorescent scales and sapphire crystals, is also patented.

Classic luminous-Ball watch
Noctilucent technology: self-luminous micro gas

Products need to have characteristics. In recent years, Ball has gathered more and more popularity on the mainland. The watch is indeed good, antimagnetic, super hard coating. Of course, the most attractive is the gas light technology. This is a self-luminous miniature gas lamp embedded in the dial scale and hands. Through this Swiss cutting-edge technology, without relying on external light or energy, the brightness of self-luminous miniature gas lamps is more than ordinary Traditional luminous paint is 100 times higher and can continue to shine for up to 25 years.
Boer Railway Chief Series World Time Zone Stopwatch

 This railway chief can be said to be a very versatile model in Bol watches, with a large 43 mm dial equipped with world time zone and 12-hour timekeeping. The signature 15 self-luminous miniature gas lamps provide luminous light, and the shock resistance has passed the 5,000Gs impact test. No matter how harsh the environment is, it can be read clearly. It is a real “tough guy.”
