How to Test the Mechanical Movement When to Buy a Watch

The mechanical movement is unfamiliar to ordinary people. The reason is that we usually only pay attention to the appearance of the mechanical watch, but it is not very concerned about the movement of the internal use. Below I will introduce how to judge the structural composition of this mechanical watch movement and its quality.

The first step, when you get the movement of a mechanical watch, just like the person you have never met, just look at the person’s appearance, then look at his dress, you can preliminarily judge his literacy and taste; and the initial feeling of the movement is exactly the same, give a first look at its appearance, and then look at each of its splinters and each transmission part of the processing level that is fine or not, the decorative texture is symmetrical or not, so you can know whether the movement is a fine product from the appearance, and thus can judge the design concept and the fineness of the manufacturing, and vice versa, the parts are rough, even the appearance is distorted, so the performance of the very ugly movement is well known.

The second step, when the movement is in the stop state, you can first rotate the arbor to wind the movement, while observing the balance spring system and the escapement, when you turn a circle up to three laps (Swiss movement in one turn is enough) the balance spring system and the escapement start and start up. This step is to test the performance of the main drive train of this movement. If it cannot be started normally, the main reason is because the movement main drive wheel has a problem with the polarization of the balance spring system.

The third step, if the balance spring system and the escapement are activated and running normally, you can continue to rotate the stem to wind the movement, and there are some points to note. The first thing is that your winding feel should be comfortable, without difficult and uneven feeling, the second is to pay attention to listen to the sound of string, which is should also be symmetrical and can not have the sound of caries, the last thing to note is that the number of windings can not be too much, generally around 20 rounds, this step is to test the performance of the winding of this movement.

The fourth step, pull out the stem to the second gear, which is the calendar fast shift of this movement. At this time, pay attention to the shifting of the stem to the second gear, the gear should be clear and you can obviously feel it is in place. Then turn the arbor to quickly dial the calendar ring. At this time, the important point to be investigated is that the calendar ring is driven by the fast-dial gear teeth. Each tooth should be skipped with a rhythm. If there is no rhythm like the swallowing, the calendar part is explained that there is a problem.

The fifth step, continue to issue the arbor to the third gear, which is the needle shift of the movement. When the shank is turned, the minute hand is moved. At this time, it is necessary to pay attention to the string, but it is still better. However, it should be observed that there will be errors when the two hands overlap to the 12 o’clock position. If you are interested, you can continue to rotate the arbor to keep the hour and minute hands rotating for 24 hours, note that the calendar ring will jump once. The main purpose is to examine the performance status of the calendar mechanism in the actual operation rather than fast-moving.

The sixth step, test the performance of the automatic train of this movement, the simplest way is to pay attention to the natural drooping position of the automatic tow, and then rotate the movement vertically, if the automatic totem keeps the orientation unchanged, which explains that the automatic rider system has flexible performance, that is the most important part of the automatic part.
