Ten popular science articles about typography terms must be used after reading them carefully!
What do you mean by flying back and forth ▼
The fly-back effect first appeared in a pocket watch made by Mr. Breguet, the originator of contemporary watchmaking, in 1794. The specific way to fly back is to make the pointer jump back to the origin at the moment when it reaches the end of the scale. Generally used for one-hour timekeeping and calendars, high-end watches will use hands to time.
For example, the supertrofeo double-chasing chronograph released by Blancpain. Due to the complexity of fly-back processing technology, the price of watches with fly-back and rebound functions is usually not very cost-effective. Please see if your watches are in stock!
What are three stitches and one thread?
The detailed name of the three-needle-one (hi) thread is actually: standard watch. The English name is Regulator, which is usually written on the watch case immediately. Its (complicated) feature is that the second hand, minute hand and watch hand (engraved) on the watch case each occupy an inner diameter scale to independently time, while the tails (gabions) of the three hands (watches) all fall on the parallel line connecting twelve o'clock to six o'clock, hence the name (micro) is "three needles and one line".
Timeshiguangge is responsible for the interaction of three needles, so the error of mechanical watch is more accurate than that of general mechanical equipment watch. Three stitches and one thread have obvious new ideas, which is most suitable for wearing as a formal watch to participate in the press conference.
What does a chronograph do?
Chronograph is a technical professional name, in which Chrono means "time" in old English and Latin, and graph means "special tool for recording" in English. The most common software in chronograph is the measuring scale system, which is usually engraved on the outermost side of the watch case or on the watch strap.
General chronographs are used to measure speed accurately. Naturally, it is difficult for high-end watches to only consider the speed limit, such as ULYSSENARDIN pulsometer, which can accurately measure the pulse rate, and JANEIRO chronograph, which can accurately measure the distance and speed of Tissot. Chronograph has a variety of structures, including one hand, two hands, single button, double button and so on. , also belongs to one of the complex functions in the watch.
What is the helium discharge gate valve used for ▼
Why does the technical diving watch have to discharge helium? At first, the volume of helium was very small, even several times smaller than that of water. When the diving watch drops to a certain depth, helium will invade the watch under high pressure. When the diver rises slowly, the gas pressure inside the diving watch will just start to be higher than the outside. At this time, if we don't take measures to eliminate helium in the watch, the watchcase strap will explode immediately.
The appearance of helium discharge gate valve represents the great improvement of the deep diving depth of diving platform. 1985 Rolex Watch developed and designed a technical professional diving watch for helium discharge gate valve for the first time, with an unprecedented depth of 2000 inches.
Difference between precision steel and titanium alloy ▼
At present, the common materials for making watches on the market are mainly fine steel and titanium alloy. It is also a composite material, but the price of watches made of titanium alloy is usually higher than that of Beijing and Hong Kong.
First of all, the net weight of titanium alloy is lighter than that of steel, only about 55% of that of steel. Secondly, titanium alloy has high corrosion resistance and strength and is not easy to rust. Many astronautics also choose titanium alloys as components of rockets and cruise missiles. Thirdly, titanium alloy is more environmentally friendly than Jinggang, and it is not easy to cause allergic symptoms of metal materials to the body. In addition, it also has memory characteristics, which is more suitable for the body and skin. Therefore, although the watch made of titanium alloy is a little expensive, it is actually more cost-effective.
Is rose gold the same as red gold ▼
Many people often see the words "18K rose gold" and "18K red gold" when looking at the materials of precious metal watches. Are they the same?
Because pure gold is very soft and easy to deform, it is not suitable for making watchcases and straps, so we choose to add a small amount of other precious metals to enhance the strength of gold.
The reddish gold case strap you see is mainly made of copper added to gold. Adding 25% of all copper to 75% of gold is red gold, and the 18K gold produced under this ratio is the reddest. If silver is added, the color will fade. The more silver is added, the lighter the bright red is. When the silver content of 18K gold is increased to 10% and the copper content is decreased to 15%, the color will be pink and become rose gold. Therefore, in fact, the difference between red gold and rose gold is not too big, but the color is redder.
Why are lettering watches so expensive ▼
The word Guilloche evolved from German guillochis. Its original intention is to create accurate and standard parallel lines and circular patterns with equipment.
It is complicated to make a carved case, which requires the sculptor's hand to control the carving knife on the edge of the carving car in real time. One hand and the CNC lathe rotate the gold plate, and the other hand exerts pressure on the carving knife to control the sharp knife, and engraves a detailed machine carving pattern with good design on the plate.
With the rotation of the camshaft, the milling head moves in different directions, and the watch case moves back and forth relatively at the side of the car, so exquisite carved lines come out. There must be no slight mistakes and omissions in the whole process here. Even if it is only in one step, all watchcases may be damaged. Therefore, the carved watch is more dynamic and gorgeous.
What is an enamel watch ▼
Enamel watches mean eternal topic discussion and the love of watch connoisseurs, and they are also incredibly expensive. Enamel watches are divided into cloisonne enamel, micro-painted cloisonne enamel and enamel. Take the most common cloisonne as an example, it is necessary to bend a gold wire less than 0.5CM into a pattern and fix it on the enamel surface of cloisonne. After the first calcination, the pattern design carved with metal wire will be filled with enamel glaze according to the design scheme.
After the cloisonne enamel coating is dried, it must be put into an industrial kiln to be calcined at a high temperature of over 800℃, so that the cloisonne enamel and the metal matrix can be integrated and become more and more stable. In the whole process, once an enamel cracks, the whole case will be damaged. The qualified rate of cloisonne enamel case is less than 50%, so it is very valuable. However, all the enamel watches that appeared at the fair were sold at high prices.
What is Goose Neck Adjustment ▼
In the detailed introduction of Glashü tte watches, most people often see "gooseneck adjustment". What role can gooseneck adjustment play?
Goose neck adjustment exists to adjust the speed needle and prevent the inevitable big deviation of the speed needle. The key principle is to use the ductility of copper sheet to hold the speed needle, and then carefully adjust the deviation of the speed needle according to a tiny screw. After debugging, the speed needle will be firmly fixed. Because the device looks like the graceful curve of the white swan's head and neck, this adjusting device is called gooseneck adjustment.
Polished patterns other than Geneva patterns ▼
The competition of high-end watches is more common in the watch core used to show the superb processing technology of information alone. Masters who make watches usually polish the watch core by hand, making the original watch core more and more beautiful and fancy, and enhancing the artistic aesthetic feeling.
The most commonly seen (happiness) is the Geneva pattern, which is famous for its appearance like the surface of the rippling Lake Geneva. Geneva pattern is divided into strip (engraved) wave type, circular wave type and radial wave type. In its (watch), strip-shaped wavy lines often occupy (add) straight hair splint and automatic pendulum with watch core on a large scale, and rubies and sapphires are also embellished (omitted) on it.
In addition to Geneva pattern, there are many more detailed sun patterns, which are radioactive and often installed on the outermost side of straight hair splint or various connecting shafts of watch core.
True bead pattern is very similar to fish scale pattern, but compared with fish scale pattern, the total overlapping area of true bead pattern is smaller and the texture is more uneven. Now it is only used in a small part to help create the texture of the watch core.
