How is the VS Panerai P.9000 movement? Be careful not to buy a one-time movement modified by a Nanning machine.

Recently, I received a customer service call from a small factory version of 441 pretending to be a big factory. The publicity of this small factory 441 is very exaggerated, claiming that all the original functions are realized, and it kills all the big factory versions on the market.I explained to the customer for a long time that this small factory product is not a big factory product, but he still doesn’t believe it. Here is a popular science article to help everyone avoid pitfalls. You should find a reliable watch dealer when buying a watch. VS Factory

After disassembling it, it turned out to be a small workshop movement that was pieced together with most of the parts removed from the Nanning 2813 movement + some gears removed from other domestic movements. They are all old parts, which should be removed from the old or broken Nanning 2813.  The quality and running time of the brand new Nanning machine are all problems. This kind of small workshop movement, which is pieced together with the parts of the domestic movement disassembled, can’t even walk steadily, but it wants to kill all the big factory versions on the market. The running time is like a roller coaster, which kills itself in seconds.
1. Disassembling the movement is not screwing, but prying, and the movement can actually be glued with glue

Mingzhu/Nanning 2813 blindly pursues cheapness, looks shoddy, and has unstable quality and travel time, which has led to it being replaced by Japanese Citizen and other movements. However, Mingzhu/Nanning 2813 is produced by a large movement factory after all, and has been complained and disliked by the watch industry. This small workshop movement may be limited by technical equipment, and is even more shoddy. Moreover, the accessories on the movement are not fixed with screws, but with glue. The unreasonable structure and poor precision make it difficult to repair and repair, and there are constant problems. It is completely a disposable movement. To disassemble the movement, you have to pry it and then glue it back. Refresh your three views! It is just a disposable movement.

2. The shock absorber is the “gourd shock absorber” used by the domestic Nanning 2813 machine. It is found that most of the accessories are the same as the Nanning machine and are interchangeable.
3. The handle of the small workshop movement is the handle of the Nanning 2813.

The relationship between this small workshop movement and the Nanning machine can be clearly seen by trying to install the core of the Nanning 2813 movement into this small workshop movement. If the core of the Nanning 2813 machine is used, then the winding clutch module of this small workshop movement is removed from the Nanning machine (which will be demonstrated below), and the bearings and accessories used in the winding system are all accessories removed from the Nanning machine.

4. The winding clutch accessories of the small workshop movement are also modified from the accessories removed from the Nanning machine, and the pinion is completely shared and interchangeable with the Nanning machine.
5. The automatic rotor bearing of the small workshop movement is also the bearing of the Nanning 2813 machine
6. The so-called realization of all original functions is completely false propaganda. The kinetic window display is still a decoration and has no function. Several wheels are added to the winding transmission wheel, and the kinetic window decorative piece is driven by the winding to rotate. The kinetic window decorative piece keeps rotating rapidly when the winding is kept on. You can see something wrong at a glance.
7. The movement of a small workshop is like riding a roller coaster. The daily error is large and jumps, the swing amplitude is low, and the polarization is large.

If the daily error is large, you can fine-tune the quick dial to adjust the error to a reasonable range. But the daily error is like a roller coaster, sometimes fifty or sixty seconds, sometimes thirty-four seconds, and sometimes forty or fifty seconds, which is a quality problem of the movement.
In the maintenance of watches, the swing amplitude problem is the most troublesome, and many people don’t know what the swing amplitude means. There is a resonator composed of a balance wheel and a hairspring in the watch movement. The stability of its oscillation cycle determines the timing accuracy of the watch. The oscillation of the balance wheel swings left and right, and its swing amplitude is the swing amplitude. There are many factors that affect the swing amplitude, such as: watch design problems, lubrication conditions, axial and radial clearances of gears, stability of the torque output of the spring, etc. After the chain is fully wound, the swing amplitude is still in the position, which means that the movement is not so healthy.
The greater the polarization, the higher the probability of the movement stopping or not moving. Polarization can be understood as large friction or disharmony between gear parts.

A normal movement with good quality has very stable travel time, stable daily error, high swing amplitude and low polarization. Compared with the roller coaster travel time of the small workshop movement, the travel time quality of the small workshop movement is worrying and cannot be saved.

8. If you look carefully, you will find that the old and new parts of the small workshop movement are pieced together, and the gears are worn and aged.

The parts and gears in the small workshop movement are pieced together, and many gears are worn and aged. Many parts are second-hand parts removed from the old or broken Nanning 2813 machine.
The brand-new Nanning 2813 machine has a very poor reputation for travel time quality. This small workshop movement, which is pieced together with second-hand parts removed from the old or broken Nanning machine, is unstable when traveling.

The poor precision of the movement motherboard and the unreasonable design doomed the fragility of this movement. Slight vibration may cause it to stop or stop.
The movement mainboard is glued instead of screws, which means that this small workshop movement is difficult to repair and cannot be repaired.
If customers fall into this trap, the watch will face the situation of either being on the way to repair or being repaired. It will never be repaired. It is worse than the IWC Portuguese watch two or three years ago. 100% of them have to be repaired, and it is very common to toss it eight or ten times.

This small workshop movement made of second-hand parts of Nanning machine relies on exaggeration and false propaganda to attract attention. It can’t even walk steadily when it is moving, but it wants to be second to heaven and earth.
Poor quality, a watch can’t even guarantee the accuracy of time. Fraud can only kill itself. Honesty is the long-term way. When buying a watch, you should find a reliable watch dealer.

9. Teach you the simplest identification method: small workshop movement uses decorative screws to fake movement bearings

The movement bearings of small workshops are decorative fake bearings, so when the automatic rotor rotates, the fake bearings will rotate with it.
The movement of the big factory version is a real bearing and will not rotate with it.
This is the simplest way to identify it. Don’t fall into the trap of buying this kind of disposable small workshop movement modified by Nanning machine.
