Some of the structure in the movement:
1, put Tuo
In 1923, Kazakhstan live through the playground to see the children playing the seesaw, replica Cartier jewelry inspired by the invention of the back of the movement in the center of the automatic Tuo, but he has not yet used bearing, the central only one axis, can not help. Tuo at both ends of the iron feet, hit the wall rebound, was called hit Tuo. This method is very poor efficiency on the chain, and later other brands (such as OMEGA four or fifties of the constellation) have switched to the spring, to provide a stronger reaction.
2, automatic compensation
Changes in temperature have a negative effect on the mechanical watch, because the temperature will change the steel as the material of the hairspring elasticity, high temperature will cause the balance wheel to slow down, low will accelerate. British JOHN ARNOLD invented truncated bimetallic compensation balance wheel, can be against that period of temperature on the impact of steel gossamer, the balance of the edge of the wheel composed of two kinds of metal, the high temperature brass has a higher coefficient of expansion than steel, He forced the balance wheel to cut inward bend, reducing the radius of the balance wheel, so that it quickly compensates the extension of hairspring. The temperature is low, the balance wheel wheel outside the opening balance wheel speed slows down.
3, distribution agencies and counters (escapement)
The escapement is a mechanism that pulls between the wheel and the oscillator (governor). fake Van Cleef &Arpels jewelry Its function is to allocate a small amount of energy to the oscillator whenever the oscillator passes through the dead point. The definition of “dead point” is the rest position that is occupied when the oscillator is stopped. At start-up, the oscillator is swung from the dead point. Each time you swing, you must disengage a tooth from the escape wheel so that the train and the pointer rotate with a very small beating and the oscillator has a very uniform follow-up frequency.
In the escapement of the release of the wheels of the very short moment, the escapement to stop, and the oscillator only when the spring is exhausted. That is, in this short moment, the wheel will be a small amount of energy allocated to the oscillator. From the second hand to visualize this trembling. So far, there are more than 10 kinds of escapement institutions developed in the world.
Today, in fact all mechanical watches are equipped with the same type of escapement, known as the “Swiss fork escapement.” It is characterized by a seemingly ship riveting one in the escapement wheel and balance between the intermediate parts. The two pieces of paper alternately stop the escapement gear and stop it. Whenever the oscillator passes through the dead point, no matter which direction it sets the disc drill into the fork of the escapement fork. Thus, the release of the escapement wheel of a tooth, and skip forward, at the same time, take the opportunity to allocate a trace of energy to the oscillator.
In addition to the escape moment through the fork in the middle of the moment with the oscillator contact, the oscillator is absolutely not affected by its maintenance agencies. This is a basic condition for making the watch accurate. In the watch industry, enjoy the advantages of the rare type of escapement known as the release of escapement. The fork escapement is the release escapement. The first generation of escapement escapement watch only in the late eighteenth century came out to the public.
4, speed control mechanism (oscillator)
The speed control mechanism or the oscillator is the true heart of the watch and clock. In the clock, the oscillator is a pendulum. In the watch the speed control mechanism is a split by two pieces of exquisite combination of parts. replica Hermes jewelry The two parts are a. b. The balance wheel is a circular round flywheel, connected by two arms or three arms to its rotating shaft. Like all flywheels, it has a certain inertia. Gossamer is a spring composed of a suitable alloy sheet, rolled into Archimedes. The center of which there is a spring and pendulum shaft connection, and the other end of the gossamer from the foreign spring fixed in the watch base. If the balance wheel moves from its equilibrium position to the other in one direction, the balance wheel will perform a deformed toughness on the gossamer, which is equivalent to the rotation angle of the balance wheel. Such as the relaxation of the balance wheel, it will be due to hairspring deformation obtained by the elastic force to restore its equilibrium position. When the balance wheel reaches the dead point, it is its maximum speed. By its impulse, it does not stop swinging, it swings an almost the same angle as the other side of the dead point.
In the absence of friction, the swing is eternal, but due to the presence of friction, it is necessary to maintain all the above parts to reduce the possibility of adding friction to the swing. Balance wheel – gossamer torque is almost isochronous. That is, the duration of the swing is not related to the swing. All watchmakers are trying to keep this timid.
So far, has more or less to reduce the causes of these qualitative change. Like the balance of the mortise, the balance of the balance wheel and the hairspring, the escapement, the temperature, the magnetic, and so on.
In the clock, the swing mechanism of the speed governing mechanism is determined by the number of single-stroke alternation per hour. Each alternately corresponds to a toothway of the escape wheel. The most frequently used frequencies are 18000a / h (2.5 Hz), 21600 a / h (3 Hz) and 28,800 a / h (4 Hz). At present, watch production line popular 28800 a / h frequency.
Watches small small, replica Van Cleef jewelry mechanical sophistication can be seen, this, balance wheel, gossam part, really great stress, modern common mechanical watch technology, Datong outside the watershed thus the most obvious, from the material, the general to the alloy, and Bimetallic compensation, pendulum is a lotus pendulum, light pendulum, weight pendulum, bimetallic truncated pendulum, etc., to adjust the simple slow needle, gooseneck fine-tuning, spiral fine-tuning, no card degrees gossamer, put the material arm number, Weight, adjust the different inside and outside the pile, the end of the curve of the same line of hair, which should be combined with the number of in order to ensure the stability of the frequency of fine stability, ah, is a simple shock with different and different, if coupled with capture Vertical that a large piece of change, a small timepiece for a prospective, stable, long, beautiful, a variety of means of purpose, too interesting.
In the center of the dial, the axle hole below the re-installed a calendar pointer, dial out of the top circle printed on the 31-day scale, and now watch the calendar form there is this, this is like a small second hand table, Can be seen in the form of instructions on the watch surface, the old wind is still popular, the traditional flavor full.

Pointer calendar structure
Now, the calendar instructions to the majority of the window, the general calendar window are open in the dial 3 o’clock position, the stars are also open at 12 o’clock position. Moreover, the current way of jumping calendar, generally have adopted the “instantaneous jump”, the advantages of fake Cartier jewelry this approach is the exchange rate is extremely fast, instantly completed, the shortcomings of the exchange when the balance of the balance wheel is relatively large.
Recently I saw an ORIS watch, is the ETA2836-2 movement. But 27 drill, while the general 2836 are 25 drill. Fine analysis, the original small seconds in the upper and lower axis of the shaft and added 2 drill, turned into 27 drill. Another feature is that it is a pointer to the calendar, the original and instantaneous jump calendar structure of all the parts are not used, jump into a fast jump. You can see which of the movements of the 31 teeth of the calendar wheel (see picture), but the analysis, this is indeed good, can effectively avoid the process of jumping, big levers and large springs are cam compression The effect of the watch on the swing. Compared with the structure of the 31-character calendar tray, it can greatly reduce the load of the drive, and the resistance is very small (basically only the pressure of the positioning wheel of the calendar wheel).
