If you want to buy watches, but these watches are not so understanding, so today we will learn about a few professional knowledge about watches, I hope to help you.
Fly BACK EFFECT APPEARS INITIALLY IN “NOW MAKE A WATCH OPEN MOUNTAIN ANCESTOR” THE DON OF BREGUET WATCH 1794 MAKE A REVERSE JUMP CALENDAR WATCH POCKET WATCH.
The reality of flying back is to let the watch rod reach the end point of the ruler to jump back to the starting point for a moment of continuous fitness exercise, generally used in an hour time and calendar, high-end watch will be used for watch rod timing.
Such as the master carpenter announced the supertrofeo double tracking needle fly back chronograph watch.
Because the production process is complex, so the price of watches with the effect of flying back is generally not quite cheap.
Three needle a detailed name is in fact: standard watch rod watch.
English name is Regulator, generally will immediately write on the watchcase.
It is characterized by the case of the watch hand, the minute hand, the watch rod each occupy an internal diameter rating scale alone time, and the tail of the three hands are falling in the 12 o ‘clock to six o ‘clock combination of the straight line, so it is called “three needle line”.
Because the three needles do their job, harm each other, so it is more accurate than the general industrial equipment watch.
Three needle with a significant creative, it is best to wear as a formal table to participate in the announcement of the venue.
Chronograph (Chronograph) is a professional name, in which chrono in Old English and Latin is the meaning of “time”, and graph in English describes “record common tools”.
Chronograph is the most widespread slide rule system, generally engraved on the most sides of the case or watch case table to carry.
A wide range of chronograph is used to accurately measure the speed of more, of course, high-end watch is not easy to only consider the speed limit, such as the precise pulse measurement of the ULYSSENARDIN pulse meter and can accurately measure the interval and speed of the JANEIRO chronograph.
The structure of the chronograph is various, which is divided into single watch rod, double watch rod, single button type, double button type and so on. It also belongs to a kind of complex effect in the watch.
Why professional diving watch as far as possible to exhaust helium?
To begin with, helium has a very small capacity, even many times less than water.
When the diving watch is reduced to a certain depth under the sea, helium will invade the watch under high pressure.
And when the engineering project is gradually rising deep dive, the internal gas pressure of the diving watch will begin to be higher than the external, at this time if you do not choose to eliminate the helium precautions in the table, watch case watchchain will immediately explode.
The emergence of helium sewage treatment cut-off valve means that the deep level of free diving of diving watch has been greatly improved.
The professional diving watch, which was first designed and developed in 1985 with a helium drain cut-off valve, guarantees unprecedented depths of 2,000 feet free diving.
At present, the most common raw materials on the market are precision steel and aluminum alloy.
The same is a polymer material, the use of aluminum alloy watch price is generally higher than fine.
To begin with, aluminum is lighter than steel by net weight, about 55 percent.
Secondly, the corrosion resistance and compressive strength of aluminum alloy is high, not easy to rust.
Many aerospace alloys are also used to make prefabricated components for rocket launchers and cruise missiles.
Once again, aluminum alloy is more ecological and environmental protection than precision, not easy to cause the symptoms of metal composite material allergy to the human body, in addition to the ability of memory characteristics, more closely combined with the human skin.
Thus aluminum alloy raw materials watch although slightly more expensive, in fact, high cost performance.
Many people look at the raw material of precious metal watch often see marked “18K rose gold” and “18K red gold” keyword, then these two are not the same?
Because gold is very soft, easy to deformation, is not suitable for creating a watch case chain, so we choose to add a small amount of other precious metals to improve the compressive strength of gold.
You see the red gold watch case chain is to gold plus copper as the core, in 75% of the gold plus 25% of the electrolytic salt water pure copper is red gold, this kind of share caused by 18K gold tone the most red.
With the addition of silver, the hue becomes lighter, and the larger the silver, the lighter the red.
When 18 karat gold, silver content increased to 10%, copper returned to about 15% of the condition, the tone will be more pink, also become rose gold.
So red gold is not really that different from rose gold, it’s just redder.
The word “Guilloche” is derived from the French guillochis.
It was originally intended to be a precise specification of hand carving with straight and circular design patterns cast by machine.
The production of Guet case is very complex, as far as possible by the hands of the engraved artist real-time processing of the carving knife before the embossed flower lathe;
One hand plus the processing center rotating gold stock plate, while the other hand is the pressure to control the edge of the carving knife, engraved on the surface of the design of a fine machine design pattern.
With the engine camshaft rotation, to move the milling head in a different direction, and in addition to the case in front of the lathe is also relative to move back and forth, fine engraved texture will then appear.
There can’t be any slight omissions in the whole process here, even a step could destroy all the cases.
Therefore, the watch is more dazzling and cool.
In the watch watch watch watch in detail we often see “gooseneck adjustment”.
What is the role of Gooseneck?
Gooseneck adjustment is to adjust the rate needle and avoid the inevitable deviation of the rate needle. The important basic concept is to use the plasticity of the metal sheet to clamp the rate needle, and then adjust the deviation amplitude of the rate needle delicately according to a tiny screw. After the adjustment, the rate needle is firmly fixed.
Because the appearance of the machine resembles a graceful trend diagram of a swan’s neck, it is called a gooseneck adjustment.
The latest market dynamics at any time to see, please pay attention to.
