Mechanical watch movement identification method

Throughout the history of the development of the watch can be divided into three stages of evolution: First, gradual separation from the early astronomical timers; Second, from the large clock to miniaturization; Third, the development of watches and electronic technology use. Its long history also contains a history of the development of human technology. Mechanical watch movement for ordinary people more strange, because we usually just concerned about how the appearance of mechanical watches, and for the internal equipped with the movement is not very concerned about. However, with the increasing quality of the consumers who buy mechanical watches themselves, there is a strong desire for the knowledge of the watch, which is increasingly interested in the mystery of the mechanical movement inside the watch. In order to popularize this knowledge, I will teach you how to identify the internal structure and quality of the mechanical watch movement in six steps: Mechanical watch movement works The first step: when you get a movement, just like met with people who have not met, the first look at the person's appearance, look at his wearing the instrument, you can initially determine his accomplishments and grade. For the initial feeling of the movement is the same reason, the first positive and negative to see how its phase, and then carefully look inside the movement can see each plywood and each transmission parts machining level is delicate, decorative lines Is symmetrical, so that you can determine the appearance of this movement is not a boutique, and thus can understand that its design philosophy and manufacturing sophistication are evident, on the contrary rough machining parts, and even Distorted, the appearance of poor quality ugly movement is also well aware of its performance The second step: At this time the movement out of stop-watch state, you can first turn the stem to winding the movement, while observing the balance spring system and escapement, when you rotate a circle up to three times (Swiss movement Generally can be a circle), balance wheel hairspring system and escapement start and start up. This step is to test the start-up performance of this movement speed control mechanism performance, if not normal start or delay start, then the movement of the speed control system is flawed, especially the escapement part may be abnormal, need professional Table repair master to deal with Stop watch movement The third step: If balance wheel hairspring system and the escapement can be started normally, you can continue to rotate the winding shaft drive motor winding system, this time special attention is: 1. Strenuous and uneven feeling. 2. Note that when listening to the sound when the wire should be uniform, there can not be eating teeth sound. 3. The number of windings can not be too much, preferably around 20 laps, this step is to test the movement of the article on the system performance Step four: If your movement is the third gear, pull out the handle shaft to the second gear, then pay attention to pull the stem to the second gear, the gear should be clearly felt in place, Then rotate the handle quick-dial additional function. General set of functions for the calendar and the calendar, then need to focus on the test place is the calendar ring or week wheel in the fast track gear driven, each tooth should be very rhythmic skip. If there is no sense of rhythm like swallowing, indicating additional features of the movement there is a problem, you need to focus on Step 5: Pull the stem to the third gear, turn the stem toggle, the minute hand, at this time need to pay attention to the place with the inspection of the winding system is about the same, still feel better. However, more attention needs to be observed when two pointers overlap to 12 o'clock position, it must be pointing to the middle can not have deviation, otherwise the display time will be error. In addition, if you are interested can continue to rotate the handle shaft so that the minute hand to keep rotating to 24 hours later, pay attention to the calendar ring will be beating once, which is to examine the calendar mechanism in actual operation rather than fast dial under the premise of the performance status Step Six: If your movement with automatic mechanism, the test of its performance is the easiest way to pay attention to automatic droop the position of the natural droop, and then rotate the movement of the vertical, if you look at the Automatic Tuo this orientation remains unchanged, that automatically The performance of the gear train is very flexible. If the automatic tuner can not maintain the same position, there may be some resistance to your automatic gear train. This part of the gear train needs to be checked. (TIPS: the so-called third gear refers to the first gear for the winding gear, the second gear for the additional function file, the third gear for the adjustment time file. The so-called two-speed position refers to the second additional function is not adjusted There are only two other gears.) Here, a movement of the recognition process is basically completed, as the general structure of the mechanical watch movement is consistent, but according to the movement of the early design of functional differences, the overall movement of the latter will be the overall layout of local conditions As the complexity of the structure increases, the complexity of each part of the movement itself is increased, and the probability of mechanical problems being raised also increases.
