In Henry Kissinger’s book On China, some of the contents of the American diplomatic
manuscript are as follows: British envoys brought gifts to the emperor of the Qing
dynasty, including mechanical timepieces representing the achievements of western
frontiers , But the Chinese emperors regarded them as tribute. This part of the content
impressed me, on the one hand depicts the expansion of Western powers at the time of
the hegemony of ambition, as well as the Chinese Cheap Replica Watches feudal imperial rule under the old
ideas, and as a watch industry history of a stage of development, mechanical watches in
that period Symbolizing the progress of science and technology. In fact, mechanical
clocks as a time recording tool, the reason why the first to develop in the West,
precisely because the West has a good advocate of scientific soil. Today, the
mechanical clock is still essentially a scientific object, aesthetic and cultural
history are the natural addition, like clocks, the scientific nature can not be
ignored.

As early as the popular clock era, as an important tool to amend the watch travel time,
oscillation system regulator has been there. Despite the development of four to five
centuries, mechanical clocks are still there are errors, the existence of these errors,
a large part of the reason is that mechanical oscillations of the clock system, has not
been able to achieve zero error, and with the long run, the error is also more and more
Big. Therefore, whether it is a clock, pocket watch, or more sophisticated modern
mechanical watch, watch fine-tuning structure has not disappeared.

In the pendulum, the oscillation system is the most important pendulum, if you observe
carefully, not difficult to find the bottom of the pendulum will generally have a small
screw, through the screw, you can change the effective length of the pendulum to
achieve the adjustment of travel time. When the gossamer was invented in the 17th
century, the gossamer with a gossamer Luxury Replica Watches also required fine-tuning to correct for
deviations in the oscillator after long-term use, except that the gossamer balance
wheel system required a redesign of the spinner. Since then the three centuries,
especially after the 19th century, the fine-tuning machine is not only a part of
mechanical time science, but also combines a number of aesthetic characteristics, both
practical and beautiful mechanical structure.

In the pocket watch and watch, our common fine-tuning structure can be divided into two
categories, one is the speed of the needle as the representative of the spinner, there
is no need to slow the needle directly through the balance wheel on the adjustment /
Code, etc. directly adjust the structure. We often say that the spinner mainly refers
to the former, the English name is generally used Regulator, today, we take a look,
those who are obvious, and very interesting spinner.

To say that the most common spinner, there is no doubt definitely ETA movement in
several, and now many high-level watches are not using the spinner, such as Omega,
Rolex, Patek Philippe, Vacheron Constantin, but there are a considerable part of the
watch to maintain With the spinner, ETA movement of the most common should be three,
many other brands of fine-tuning structure Swiss Replica Watches is the three variants. But need to know is
that from the pocket watch to the watch, fine-tuning at least hundreds of structures,
it is difficult out one by one out.

ETA is the universal watch movement well-deserved overlord, it feeds a large number of
independent movement production capacity of the brand, you can buy most of the general
movement watch, or is equipped with ETA movement, or installed ETA movement is based on
the variants. ETA 2824, ETA 2892, ETA 7750, ETA 6497 (or ETA 6498), ETA 2671 and so on,
in which ETA 2824 and the ETA movement of the ETA The 2892 uses the same spinner, the
ETACHRON trim with an opening screw.

This spinner structure is simple, the effect is significant, the opening of the screw
on the balance wheel on the scale of the plywood, you can adjust the speed of travel
time. All of these spinner, basically follow a principle, that is, change the location
of hairspring trace, affect the effective length of the hairspring, thus changing the
speed of travel time. ETA 7750 series of chronograph movement, the use of a pointer-
type fine-tuning structure, its effect and the screw is the same fine-tuning, but the
two can adjust the travel time and speed range will be different. ETACHRON also a
relatively common needle structure, but also a pointer structure, relative to the ETA
7750 this pointer type, it should be simple, from the Bosley speed needle, the direct
dial needle can adjust travel time, this patent About 1755, has now evolved into a very
rich form.

These three structures look different, but the principle is the same, but I still do
not know why ETA 2824, ETA 2892 is eccentric screw with fine-tuning pin structure, ETA
7750 with a screw pointer type spinner, ETA 6497 this use Is a simple pointer, if any
friends who know the table, but also look at the message. I passed and professional
watch repair master exchange, given the Replica Watches China answer is not absolute, because these movements
through different brands of modification, some will change the speed of the needle
structure, so not to say that a movement must use a certain Type of needle structure.

In addition to ETACHRON these three spinner, the most common, but also the most
popular, and may have to goose neck fine-tuning, and gooseneck fine-tuning beautiful
shape, because the spinner on the compactor has a beautiful curve, the shape of geese
Neck, hence the name. Not only modern watches, as early as the prevalence of pocket
watch, gooseneck necklace has been widely used in pocket watch.

Gooseneck fine-tuning there are several important components, one is fine-tuning
screws, one is the speed pointer, there is a gooseneck spring. The gooseneck spring is
responsible for applying a certain amount of pressure to the fine adjustment screw,
which helps to make the adjustment screw more precise and does not cause excessive
adjustment. The use of screws to promote the speed pointer, but also to be able to more
accurately speed pointer to go through a certain scale, this screw adjustment, than the
ETACHRON screw adjustment, to be more precise. Gooseneck fine-tuning This fine
adjustment, can more accurately correct the travel time error, in general, gooseneck
tuning can adjust the speed of 5 minutes / day within the travel time error, and can be
accurate to plus or minus 5 seconds / day.
