Panerai 441: Be careful not to buy a disposable movement converted from a Nanning movement

The Panerai Wristwatch model is produced by the leading Super Clone manufacturer workshops with a solid stainless steel case, standard case diameter and ETA 2824-2 caliber in Swiss norms architecture. It is among the most successful 1:1 super clone watch reviews on the market, with its sapphire crystal AR coating glass, original case tolerances and detailed workmanship.

When I opened it and looked at it, it turned out that it was actually a small workshop movement, assembled by adding most of the parts removed from the Nanning 2813 movement and some gears removed from other local movements. Moreover, the parts are all old; It was most likely removed from old or broken mechanisms from Nanning 2813. While the quality and operating precision of even the brand new Nanning mechanism is problematic, the small workshop mechanism assembled with parts dismantled from these domestic mechanisms cannot even move properly; But it claims that it will overshadow all the major factory versions on the market. With its roller coaster-like operating precision, however, it outshines itself.

1. Disassembling the mechanism cannot be done by turning a screw, it is necessary to separate it with a lever; In this mechanism, the parts can be glued together.

Mingzhu/Nanning 2813 looks sloppy because it blindly pursues cheapness; It has been surpassed today by movements such as the Japanese Citizen due to its instability in quality and work. But Mingzhu/Nanning 2813 is, after all, the product of a large movement factory, yet it is constantly criticized and belittled in the watchmaking industry. The mechanism of this small workshop is much more sloppy, probably due to lack of technique and equipment. Moreover, the parts in the mechanism are not fixed with screws, but are glued together. Its structure is illogical, its sensitivity is low; This makes repair difficult or even impossible, causing constant problems. It is literally a disposable mechanism. You need to use leverage to disassemble it, then glue it back on with glue. It turns people's perception upside down! It's simply a disposable mechanism.

2. The shock absorber is the “gourd shock absorber” used in the domestic Nanning 2813 movement; I noticed that most of the parts are the same as the Nanning mechanism and are interchangeable.

3. The winding spindle of the small workshop mechanism is directly the winding spindle of Nanning 2813

The relationship of this small workshop movement with the Nanning movement becomes clear when you try the winding shaft of the Nanning 2813 movement by inserting it into this small workshop movement. Since the winding shaft of Nanning 2813 fits, it means that the winding-grip module of this small workshop mechanism was also removed from the Nanning mechanism (I will prove it below); The bearing and the parts used in the installation system are all parts removed from the Nanning mechanism.

4. The installation-grip parts of the small workshop mechanism were also removed and replaced from the Nanning mechanism; It is completely common and interchangeable with the small gear Nanning mechanism.

5. The automatic rotor bearing that enables the installation of the small workshop mechanism is the bearing of the Nanning 2813 mechanism.

6. The so-called exact realization of all original functions is a completely false promotion. The power indicator window is actually just an ornament, it has no function. A few cogs have been added to the installation transfer wheel; With the installation movement, the ornament plate on the power indicator window rotates. As you wind it continuously, the ornamental plate on the power indicator window also rotates rapidly. At a glance it is obvious that it is wrong.

7. The operation of the small workshop mechanism is really like riding a roller coaster. Daily error is large and bouncy, oscillation amplitude is low, hit deviation is high.

If the problem was just the large daily error, it would be possible to fine-tune it with the quick-adjust needle and bring the error to a reasonable range. But the daily mistake is like a roller coaster; Next thing you know it's fifty-sixty seconds, next thing you know it's thirty-forty seconds, next thing you know it's forty-fifty seconds; This is simply a quality problem of the mechanism.

The most troublesome issue in watch repair is the oscillation amplitude problem, and most people do not know what the oscillation amplitude is. Inside the clock mechanism, there is a resonator consisting of a balance wheel and mainspring; The stability of its oscillation period determines the time measurement accuracy of the watch. The oscillation of the balance wheel is a back and forth movement; The width of this oscillation is the oscillation amplitude. There are many other factors that affect the oscillation amplitude: design problems of the watch, lubrication condition, axial and radial clearance of the gears, stability of the mainspring torque output, etc. If the oscillation amplitude is still at the bottom level even though the winding is fully loaded, this is an indication that the mechanism is not very healthy.

The greater the accuracy deviation, the greater the chance that the mechanism will stop secretly or not work at all. You can understand accuracy in layman's terms as the magnitude of friction between the gear and the parts or the degree of mismatch.

A good quality, normal mechanism works very stably: log error is balanced, oscillation amplitude is high, hit deviation is low. Compared with the operation of the small workshop mechanism like a roller coaster, the working quality of the small workshop mechanism is alarming and cannot be saved.

8. If you look carefully, you will see that old and new parts are mixed together in the small workshop mechanism, and the gears are worn and worn.

The parts and gears in the small workshop mechanism are used in a mixture of old and new, many gears are worn and worn out. Most of the parts are second-hand parts removed from old or broken Nanning 2813 movements.

While the working quality and reputation of even the brand new Nanning 2813 movement is very, very bad, this small workshop mechanism, compiled with second-hand parts dismantled from old or broken Nanning movements, cannot even run properly.

The precision of the main sinker of the mechanism is low, its design is unreasonable; This reveals the fragility of the mechanism from the very beginning. Even a slight jolt can cause it to stop stealthily or not start at all.

The main plate of the mechanism is glued instead of fixed with screws; This makes it obvious from the beginning that this small workshop mechanism is both difficult to repair and will not be fixed.

The watch of the customer who falls into this trap will either be on the way to repair or in the process of being repaired. It won't get better in a lifetime. Even worse than the IWC Portugieser chronograph of two or three years ago; It is 100% repairable, and having to deal with it eight or ten times will be a very common situation.

This small workshop mechanism, compiled with second-hand parts of the Nanning mechanism, is trying to attract attention with exaggeration and false promotion; He can't even walk properly, but he claims that he can outshine the earth and the sky.

The quality is bad; A watch only eclipses itself by dishonesty if it cannot even guarantee to tell the correct time. The long-term path is fair dealing; When buying a watch, consult a reliable seller.

9. Let me teach you the simplest way to distinguish: the small workshop mechanism uses a fake ornamental screw instead of a mechanism bearing.

The bearing of the small workshop mechanism is a fake bearing for ornamental purposes; Therefore, when the automatic rotor rotates, the fake bearing rotates with it.

In large factory version mechanisms, the bearing is real and does not rotate with the rotor.

This is the simplest method of differentiation. Don't fall into the trap and buy these small disposable workshop mechanisms converted from Nanning mechanisms.
