Mechanical watch movement recognition method

Mechanical watch movement recognition method.

Throughout the history of the development of watches and clocks, can be divided into three stages of evolution: First, from the early astronomical timer gradually separated; Second, from the large newspaper to the miniaturization of the excessive; Third, the development of electronic and electronic technology use. Its long history contains a history of human technology.

Mechanical watch movement for ordinary people is relatively unfamiliar, because we usually just concerned about the appearance of mechanical watch how, and for the internal movement is not very concerned about the movement. However, with the purchase of mechanical watches, the quality of consumers themselves is getting higher and higher, for the mystery of mechanical watch internal movement more and more interested in the kind of knowledge for the table of desire is very strong. In order to give you universal access to this knowledge, I will be divided into six steps to teach you how to identify the internal structure of mechanical watch movement and quality:

The first step: When you get a movement, just like the people never met with the same, first look at the person's looks, and then look at his instrument, you can initially determine his qualities and grade. For the movement of the initial feeling is the same reason, first and foremost to see how it looks, and then carefully look inside the movement can see each of the internal splint and each transmission parts of the machining level is delicate, decorative lines Whether it is symmetrical, so you can determine this movement is not from the appearance of fine, and thus can understand that its design and processing of the fineness are visible, and vice versa rough processing, and even distorted, ugly appearance of the goods with a poor performance also well aware of the movement

Step 2: At this time the movement out of the state for the table, you can turn the handle shaft to the movement of the winding, while watching the balance spring system and escapement, when you turn up a circle of three times (Swiss movement The general circle can be), balance spring system and escapement began to start and run up. This step is to test the speed control mechanism of the starting performance, if not normal start or delayed start, then the movement of the speed control system is flawed, especially the escapement part may be abnormal, the need for professional Repair table master to deal with

Stop the state of the movement

Step 3: If the balance wheel system and the escapement can start normally, you can continue to turn the handle shaft drive the winding system, this time in particular need to pay attention to the place is: 1. Your winding feel comfortable can not have very Struggling and uneven feeling. 2. Note that listen to the sound when the winding to be uniform, can not have the voice of eating teeth. 3. The number of rings can not be too much, the best in about 20 laps can be, this step is to test the movement of the line on the performance

Step 4: If your movement is three stalls, pull out the handle shaft to the second gear, then pay attention to pull out the handle shaft to the second gear, the stalls to be clear can obviously feel in place, And then turn the arbor speed dialing additional function. Generally set the function of the calendar and the calendar, then need to focus on the test area is the calendar ring or Zhou Li wheel in the fast-dial teeth, each tooth should be very rhythmic jump. If it is gulping that there is no sense of rhythm, indicating that the movement of the additional part of the problem, need to focus on

Step 5: pull out the handle shaft to the third gear, turn the handle when the shaft toggle, minute hand, then need to pay attention to the place with the test when the chord almost, still feel better. However, it is more important to note that when the two fingers overlap to 12 o'clock, it must be pointing to the middle can not be deviated, otherwise the display time there will be errors. In addition, if you are interested, you can continue to turn the stem so that the hour and minute hands continue to turn after 24 hours, pay attention to the calendar ring will be bouncing once, this is to examine the calendar in the actual operation of the actual operation rather than fast state

Step 6: If your movement with automatic mechanism, the easiest way to test its performance is to pay attention to the automatic state of the natural sagging position, and then vertical movement of the movement, if you always keep this orientation unchanged, that automatic Wheel performance is very flexible, if the automatic Tuo can not maintain the same position, then your part of the automatic wheel line there may be resistance, need to focus on checking this part of the wheel.

(TIPS: the so-called third gear is the first gear for the last file, the second gear for the additional function file, the third gear for the adjustment time file. The so-called two gear is no second additional function adjustment Stalls, only the other two stalls.)

Here, a movement of the identification process is basically completed, because the mechanical watch movement is the same structure, but according to the movement of the early functional design differences, the overall movement of the latter part of the layout will be local conditions , With the structural complexity of the increase in the movement itself to increase the complexity of the various parts of the mechanical structure of the probability of the problem will increase.
