Identify the mechanical watch movement good or bad

The reason why mechanical watch movements are unfamiliar to ordinary people is that we usually just pay attention to how the mechanical watch looks, and we don’t care much about the internal use of its movement. The following is a step-by-step guide on how to tell if a mechanical watch movement is good or bad.

First move

When you get a mechanical watch heart, just like the meeting of people who have never met, first look at the person’s face, and then look at his dress, you can initially judge his education and taste; and the initial feeling for the heart is also the same, first front and back to see how it looks, and then carefully examine it, which can be seen in each piece of the plate and each transmission parts processing level whether The first thing you need to know is whether or not the machine is a fine product in terms of appearance, and you can judge the design concept and the fineness of the manufacturing process, but on the other hand, the parts are roughly processed, even distorted and deformed, and the appearance of the machine is very poor and ugly.

Second move

At this point, the heart is stopped, you can first turn the shank to wind the heart, while observing the balance-spring system and the escapement, when you turn a turn of up to three turns (usually one turn for Swiss machines), the balance-spring system and the escapement start to start and run, this step is to test the performance of the main drive train of the heart, if it does not start properly, the main reason If it doesn’t start properly, the main reason is because the main drive wheel of the machine

Third move

If the balance spring system and the escapement are up and running in time, you can continue to wind the heart by turning the shank, and there are a few things to keep in mind, first of all, your winding should feel comfortable and not very hard and uneven, and secondly, you should listen to the sound of the winding should be even and not have the sound of gnawing teeth. This step is to test the performance of the winding wheel system of this machine.

Fourth move

Pull out the shank to the second gear, that is, the calendar fast dial gear of this machine, this time to pay attention to dial out the shank to the second gear, the gear should be clear and can clearly feel in place, and then turn the shank fast dial calendar ring, this time need to focus on the calendar ring in the fast dial wheel teeth, each tooth should be rhythmically skipped, if it is like swallowing a lump, no sense of rhythm means that the calendar part has problems. The problem.

Fifth move

Continue to issue the shank shaft to the third gear, which is the dial gear of this machine, turn the shank shaft to dial the hour and minute hands, what needs to be noted at this time is similar to the winding, still feel good, but more important to observe is that when the two hands overlap to the 12 o’clock position there will be errors, in addition you can continue to turn the shank shaft to let the hour and minute hands keep turning until after 24 hours, notice the calendar ring will jump once This is to examine the performance of the calendar mechanism when it is actually running rather than toggling quickly.

The sixth move

This is the last step to check the performance of the automatic wheel system of this movement. The easiest way to do this is to note the natural downward position of the rotor and then turn the movement vertically.
