Watch has a long history, which contains rich knowledge, especially for the understanding of professional terms and movement and watch adjustment and maintenance are very professional people can, next, we learn how to identify the Swiss mechanical watch movement.
The FIRST STEP: WHEN YOU GET A MOVEMENT, MEET WITH THE PERSON WHO HAS NEVER MET THE SAME, LOOK at the appearance of the person first, and then look at his wearing instrument, you can preliminarly judge his accomplishment and grade.
Preliminary feeling for the movement of the same is true, positive and negative to see how it’s appearance, again carefully studied movement inside can see every piece of plywood and a transmission parts machining levels are exquisite, adornment grain symmetry, so you can determine the movement from appearance is fine,
And from this can understand its design concept and processing and manufacturing of the fine degree is visible, on the contrary, the parts processing rough, even distorted deformation, appearance of the ugly movement performance is also well known;
The second step: at this time the movement out of the stopwatch state, you can first turn the shaft to the movement winding, while observing the balance spring system and escapement, when you turn a circle of up to three turns of time (Swiss movement generally a circle can), balance spring system and escapement start and run up.
This step is to test the vibration performance of the movement speed regulating mechanism, if not normal start or delayed start, then the movement of the speed regulating system has defects, especially the escapement part may have abnormalities, the need for professional repair table master to deal with;
The third step: if the balance spring system and escapement can start normally, you can continue to turn the handle shaft drive the winding system of the movement, at this time special attention is: 1.
Your winding feel should be comfortable and not labored or uneven.
2. Pay attention to the sound of the winding should be even, and there should be no gnawing sound.
3. The winding number can not be too much, it is best to be about 20 turns, this step is to test the performance of the movement on the system;
The fourth step: if your movement is three gears, pull out the handle shaft to the second gear, then pay attention to pull out the handle shaft to the second gear, the gear should be clear can obviously feel in place, and then turn the handle shaft to dial additional functions.
Generally, the function is set for the calendar and the weekly calendar. At this time, the key test is the calendar ring or the weekly calendar wheel driven by the fast dial wheel teeth. Each tooth should be skipped rhythmically.
If it is swallowed without a sense of rhythm, there is a problem with the additional function of the movement, which needs to be looked at.
Step 5: Pull out the handle shaft to the third gear, turn the handle shaft toggle, minute hand, at this time need to pay attention to the same as the test winding system, still feel good.
However, more attention should be paid to observe that when the two Pointers overlap to 12 points, they must point to the middle without deviation, otherwise there will be error in the display time.
In addition, if you are interested, you can continue to turn the handle shaft to keep the minute hand turning until 24 hours have passed. Note that the calendar ring will jump once. This is to see how the calendar mechanism performs under the premise of actual operation rather than quick movement.
Step 6:
If your machine with automatic mechanism, test its performance is the simplest way is to pay attention to the position of the automatic tuo natural prolapse, and vertical rotating machine, the automatic tuo if keep the constant bearing, showed that the performance of automatic gear train were flexible, if automatic tuo cannot keep the same position, then your automatic gear train part there may be resistance,
We need to focus on this part of the gear train.
Speaking of which, a machine core identification process was basically completed, due to mechanical watch movement of gross structure is consistent, just according to the movement of the early stage of the functional design, movement in the late overall layout will adjust measures to local conditions, with the structure complexity increases the movement of ascension of complicated parts, the probability of mechanical structure problem will increase.
The above is a small series for you to introduce how to identify the Swiss mechanical watch movement, more knowledge please pay attention to.
