There are many different versions made several years ago that was treated as the most luxury fake watches that are closest to original models. At that time, PAM 127 was already the same as the real one, and nobody can spot it as a replica. A new boss was in charge of the factory one year later, and he was more likely to copy Audemars Piguet, Submariner, and Blancpain, therefore, Panerai PAM 127 was stopped for production. In order to meet the demands of a large number of watch fans on PAM 127, one factory called S manufactured 127, but they did not use sapphire crystal, and the quality could not be compared with the one of Noob. However, another big factory Z cooperated with Noob and produced PAM 127 again this year, this time they not only perfectly presented Noob’s quality, but also made some modification on that replica watch, so this ultimate version is closer to the real model. 
The biggest modification is on the movement, which is a Seagull manual winding caliber, and it was upgraded by the Z factory to the outlook of Swiss ETA 6497-2. Now, this movement is perfectly cloned and you are not able to find the difference between it and a real ETA 6497. Please check these photos closely, blued steel screws and engravings on movement are totally the same as Swiss ETA 6497. About this clone manual winding movement, you can’t wind it too tight, about 20 rotations one time. The case is made of 316L stainless steel, brushed, while the round bezel is polished. The case is measured to be 47mm in diameter and 17.5mm thick.
Crystal is not flat, and it is a domed sapphire crystal, featuring colorless AR Coating, which is Swiss standard. There is a black sandwiched dial under the crystal, which has 3-6-9-12 Arabic numbers and stick hour markers. The disc on the bottom is fully applied Super-luminova, which looks a little patina. But the hour markers and hands will emit strong green light in the dark. A small second subdial is positioned at 9:00, different from other PAMs, there are only digits “1950” printed at 6:00 on the dial, and it looks a little retro and reminds cheap replica watches fans of those vintage PAMs. 
The color of the leather strap is brown, it is different from Panerai’s ASSO leather band, this type of leather is softer to wear, so you can also try a black rubber strap on this PAM 127. You will get so much fun from exchanging straps on a replica Panerai watch.

The definition of the chronometer in our mind is an extremely accurate timepiece, correct? But, what’s in detail? You know that the chronometer it today grew out of the pursuit of a solution to the problem of determining longitude at sea. That solution, it turned out, was to know when it was noon at your location on the open ocean and, knowing what time it was in Greenwich, England (hence, the use of GMT) at the same time. Use simple arithmetic to find the time difference and you could find out how far west or east you were. That’s longitude.
But knowing the time in Greenwich was the rub. You may want fake watches on board your ship that was set to Greenwich time. OK, that’s simple enough. You set the particular clock to Greenwich time before you leave England. But how do you know that clock isn’t running slow or fast? Well, you have to trust the accuracy of said clock. And that’s where chronometers come in.
Normally speaking, the movement that’s been certified by COSC and achieved chronometer status is accurate to -4/+6 seconds per day. But there’s a little more to it than that.
The testing it takes to achieve a COSC certificate is based on ISO standard 3159. A movement is tested over fifteen days, in five positions, at three different temperatures. Measurements are made each day and are compared to two atomic clocks. The standards for achieving a chronometer certificate are as follows:
And to achieve this kind of performance, there are many other physical effects and circumstances that need to be mitigated, avoided, or overcome, with regard to individual components and their assembly.
The dimensions of each component have to be controlled. Design tolerances – the degree to which each piece part is dimensionally identical to its siblings in a manufacturing lot, and to the original design dimensions – must be maintained. This also relates to how each component mates to the parts it interacts with. Temperature effects include viscosity changes in lubricants and thermal growth or shrinkage of component parts.
There are still going to be infinitesimal differences in the build of each movement, even though it is properly accounted for. These are due both to infinitesimal differences in the individual components used to build each movement, and minute differences in alignments – even with locating pins and shoulders.
These small differences are enough to cause differences in how each movement runs before adjusting. Therefore, a watchmaker is needed to make those final adjustments and bring the movement into spec so it can pass the COSC tests. However, you can see how making and adjusting a replica watch movement with over 200 parts to perform within seconds per day is no small feat.
