APF Audemars Piguet ROO Chrono Secs@12

There are a lot of replica Audemars Piguet watches that are selling very well in our market, Audemars Piguet is always hot, not like Panerai, its popularity never decreased in recent years. The competition in the field of replica Audemars Piguet is high, many watch factories are producing top quality replicas of Audemars Piguet, as far as I know, ZF, APS and XF are three factories that are making super clone AP, the Royal Oak 15400 and 15500 from ZF and APS are best-selling models, the competion between these two factories is fierce, XF also makes replica AP, their 15202 is considered to be the best. In my opinion, APS has a great potential because this factory is powerful in researching and developing movements.

Except Royal Oak 15400, 15500, 15202, 15710, there was another popular AP replica before, it is the Audemars Piguet Royal Oak Offshore Chrono Secs@12, it has a chronograph function, with a working small-second subdial at 12 o’clock, when we mentioned this watch, we will think of J12 factory, which makes the best replica of this watch before, now J12(JF) was closed, this factory does not exist any more, it is a great pity, now it is hard to find a super clone of Audemars Piguet Royal Oak Offshore Chrono Secs@12, but today, I will give you an alternative, it is AP factory, also named APF, they make top quality replica of AP ROO Chrono Secs@12. When people talk about AP from J12 factory, I still remember its super finish on case and bracelet, but for the replica of AP ROO Chrono Secs@12 made by J12, there is a big defect, its the movement, which has a very big repair rate. While on the replica of AP ROO Chrono Secs@12 made by the new AP factory(APF), few people complained its movement, their movement seems to be more stable. APF has made a few models, today I shared photos of one model, seeing from the crystal back, I see its movement also has very beautiful decoration. The watch also comes with one extra rubber band.

Do I recommend APF? Yes, why not? And it is the only factory I recommend if you want a good quality replica AP ROO Chrono Secs@12, although its case finish can not be compared with that of J12 AP. Its movement is more stable, but I still suggest you do not use the chrono pushers too often.

Top Ten Best Sellers in 2022

It is nearly the end of 2022, watches factories are going to be off work and spend our traditional Chinese New Year holiday soon. I think some factories will stop accepting orders after middle December, all of them will close their stores in the end of December, so you still have some days to order the best replica watches from the factories. In 2022, it is really hard for us to do business in this industry, first, it is difficult to receive payment from abroad, I do not know if there will be any payment methods can be used in 2023. Second, our government’s attitude towards the coronavirus indeed has an effect in this business, the shipping speed was greatly affected at least. Third, the fighting against counterfeit goods also exists, because of this, many famous watch factories were closed such as Noob, AR and JF. But super clones will always exist if there are needs. Today, I will make a summary of the top ten best-selling replica watches in 2022, all of these watches have been introduced on my blog.

1.Clean Daytona 116500 V2

The Daytona 116500 replica must be on this list, it deserves the first position. Both BT factory and Clean factory make this watch, but I think Clean has more advantages on this watch than BT. Now the latest version of this watch from Clean has come to V2. The Daytona is equipped with a super clone 4130 movement that has the same functions as real Rolex 4130 movement. The ceramic bezel and hands on the dial have been greatly improved by Clean. It is the best Daytona 116500 in the market.

VSF Submariner 126610LN

2.VS Factory Submariner 126610LN

Submariner 126610LN has a 41mm case diameter. Several factories are making the replica Submariner 126610LN, JVS, EW, Clean, but for the 41mm Submariner, I think VS factory makes the best one in our market. No other factories can be compared with VS if you want to choose a 41mm Submariner, whether the black one or starbucks. The movement in the 41mm Submariner is a custom-made 3235, which is developed by VS factory and is considered to be the best clone 3235 movement in our market.

3.Clean Factory Submariner 116610LV

This watch deserves a position in the list. 40mm green Submariner 116610LV, I only recommend the one made by Clean factory. First, Clean is a factory that specializes in making ceramic bezels for Submariner, they did not make replica watches before, but they had been famous for making ceramic bezels, especially the green ceramic bezel used by the Submariner 116610LV, which is considered to be the best green ceramic bezel in our market. About the replica Submariner 116610LV, VS factory also makes a top quality one, but I still recommend the Clean version, we should respect the big contribution Clean has made in the development of super clone Submariner.

4.Clean Daytona 116519 Grey

Now Clean factory has a large collection of Daytona, for the models with rubber band, this 116519 is the best-looking one and also the most popular one. The watch uses a super clone 4130 movement with fully working chronograph function, another selling point of the watch is its rubber band, which is not like the one on the Daytona made by other factories, the rubber band made by Clean is the best and has a very comfortable wearing experience, by the way, Clean offers different length combinations for the rubber band to meet wrist with different size.

VSF Rolex Datejust II Black

5.VS Factory Datejust 41mm Jubilee Black

VS factory has published a lot of Datejust II models, besides this black one, other colors like blue, silver and gray also popular. Clean also makes this black one, both factories make the Datejust with real 904L stainless steel, but VS uses a better 3235 movement that features a longer power reserve. More people choose the Datejust 2 from VS. It is not strange that all watches are coming from Rolex in top five best sellers.

6.APS Factory Royal Oak 15400 V3

The replica AP Royal Oak 15400 is always a hot watch in our market, I recommend two factories, ZF and APS, both make the best. But after the release of V3 edition from APS factory, I suggest you buy from APS now. Its clone 3120 movement is closer to genuine AP 3120 calibre, it is the most authentic super clone in-house 3120 movement in our market.

7.PP Factory Nautilus 5711 Blue V4

PP Factory, also called PPF by us, its Nautilus 5711 replica is the best-selling replica Patek Philippe watch. In my opinion, both 3K factory and PP factory make the best Nautilus 5711 replicas, PPF is the first factory to make this blue dial in a correct color that is closest to genuine watch, now its version has been updated to V4, considering the Nautilus 5711 usually out of stock from 3K, I recommend PPF first.

8.VS Factory YachtMaster 42mm

Another Rolex, yes, I won’t be surprised if they are all Rolex watches in this list. This replica YachtMaster in 42mm is very popular in the last two years, the best one is made by VS factory. JVS and GM factory also make this watch, but the clone 3235 movement made by VS is the best. However, you can not get this watch immediately if ordering from VS, you need to wait for several days, JVS and GM usually have the watch in stock.

VSF Omega Seamaster Blue

9.VSF Seamaster Diver Blue

Now the Seamaster from VS factory finally becomes the flagship model of VS factory, before in the top ten list, there would be several Panerai models, but this time no Panerai watches, in 2022, the need for Panerai replica watches in our market greatly decreased. But the replicas of Omega Seamaster from VS factory still very hot, just like the time before the closure of VS two years ago. Now VS factory back to the industry again and their business back to normal, the orders of VS Seamaster 300m Diver blue immediately increase.

10.Clean GMT-Master II Batgirl

I learned its name from readers, Batgirl, it is the GMT-Master model with black/blue ceramic bezel and jubilee bracelet. Several factories are making this replica GMT-Master, besides Clean, V9 and GM are two other factories I also recommend, but Clean makes the best one, if you consider its high price of Clean, the versions from V9 and GM are also good. The Batman and Batgirl, both are super clones from Clean, Batgirl, the genuine watch uses a 3285 movement, while on the replica, it is engraved with “3186” on the movement plate, I still hope Clean can correct this even people won’t open the case back.

How good is the AP RO 15400 from APS factory?

Audemars Piguet RO 15400 Replica
Audemars Piguet Royal Oak 15400 Blue Replica
Audemars Piguet Royal Oak 15400 White Replica

Royal Oak 15400 has already been the best-selling replica Audemars Piguet watch since JF and ZF made it, these two factories have competed with each other for more than two years in the sales of AP Royal Oak 15400, J12 is the first factory to make AP Royal Oak 15400 replica, they have owned this watch for more than five years, they usually improved the watch, now the latest version has been updated to V5. While ZF started to make the replica AP RO 15400 two years ago, and at the beginning, the case finish and bracelet finish are not as good as that of J12 15400, but ZF improved the quality later, now, I think J12 and ZF have the same quality 15400.

APSF Audemars Piguet RO 15400 Replica
Audemars Piguet RO 15400 Black Replica

APS is not a new watch manufacturer, before making this AP RO 15400, they replicated the Royal Oak Perpetual Calendar 26574, whose quality is good and many people bought it. In 2021, APS factory unveiled Audemars Piguet Royal Oak 15400 replica, the biggest highlight is their movement, which is considered to be the best clone 3120 in our market, I think that is also the reason why APS 15400 has a higher price than J12 and ZF.

Audemars Piguet RO 15400 SS Case
Audemars Piguet RO 15400 Crown

Because of the in-house 3120 movement, APS 15400 has the most correct case profile, its diameter is 41mm, but the case thickness is 9.8mm, which is closest to the thickness of genuine watch, the case thickness of JF or ZF 15400 is more than 10mm. APS also claimed that the case construction and assembly method are the same as original, all case parts can be interchanged with genuine watch. Certainly, the most important is the movement is no longer a “fake 3120” based on Miyota 9015 that is added with extra plates.

Audemars Piguet RO 15400 Black Checkered Dial

I measured the case thickness, it is around 9.7mm or 9.8mm, if you do not get both ZF 15400 and APS 15400 in hand, you can not find this subtle difference, but some people do care that. By the way, it is very difficult for a watch manufacturer to reduce the case thickness of a replica watch while maintaining a genuine case construction, like on this AP RO 15400, APS factory managed to develop this clone 3120 movement and improved it, and they finally got a perfect result.

APS Factory Audemars Piguet RO 15400 Replica

So, I make a summary here, how good is the AP RO 15400 from APS factory? Two points can explain. First, its best clone 3120 movement that looks closest to real AP 3120 Calibre. Second, correct case thickness and all case parts can be used on a genuine AP 15400. About the stainless steel AP RO 15400, APS factory has published three models, each has a different dial color, there are black, blue and white. Please check photos in this article.

Top 10 Best Selling Replica Watches in 2019

Top 10 Best Selling Replica Watches in 201It is the end of 2019, now time to make a summary of this year. The growth of replica watch industry in 2019 is rapid, watch manufacturers in our market also introduced a lot of good quality replica watches, it is an amazing year. Noob, AR, GM and other factories published a lot of replica watches with superior quality in 2019, this was unimaginable in the past, now it is happening. In return for loyal readers of my blog, today I will post an article to introduce the best-selling replica watches in 2019, I choosed ten watches to describe in this article, actually, you know, there are certainly more than ten, and some other watches are even sold better than these ten pieces, however, the ten watches in this article must be the ones that receive most attention. Here they come below.

1.Noob Daytona with Super Clone 4130

Daytona must be Noob’s hero product in 2019. In the first half of 2019, Noob gradually lost their advantage when facing AR factory because AR firstly used 904L stainless steel in their replica Rolex watches. However, in the second half of 2019, with the release of their Daytona products made with 904L stainless steel, Noob began to get competitive advantages again. So, I must say Daytona is the hero product of Noob in this year. Noob made improvement on their Daytona three times in this year, the latest version until now is V3, several clients who bought Noob Daytona are all satisfied with the quality.

Noob Rolex Daytona V3 White Dial

2. ARF Submariner

Why do I recommend Submariner from AR factory in the second position? Maybe a lot of people do not agree with me, they think the Rolex Submariner of Noob should be in this position or even in the first position. I do not think so. Take Submariner 116610LN or 116610LV for example, Noob has improved both models for several times, now the version is updated to V10, they have also been proven to be very perfect, however, I do not think the Submariner from Noob can be compared with the one from AR factory, at least in case and bracelet finish, as well as bezel construction, the Submariner from AR factory is better. Now, AR factory has updated their 116610LN and 116610LV to V3 edition, they also offer 3135 movement option like Noob.

3. PPF Nautilus

Actually I feel very struggled to put the PPF Nautilus in this position, because the Nautilus from MKS and PF is also very good. But in the second half of 2019, when people talking about Nautilus, it is all about PPF. Among all Nautilus models PPF made, the best-selling must be the one with “blue/gray” dial. Please see photos below, the dial is actually blue, but it also looks a bit gray. Actually before PPF, the best-selling Nautilus is coming from MKS and PF, however, among those three watch manufacturers, PPF is the only one that makes the correct blue dial of Nautilus, plus the high demand of Patek Philippe Nautilus in genuine watch industry, so I think this is a reasonable position for PPF Nautilus.

PPF V2 Nautilus

4. JF Royal Oak 15400

Royal Oak is the bracelet-style jewelry for men, and 15400 is the most popular model. If you do not like Rolex, then a Royal Oak 15400 is a must-have bracelet timepiece for a man. Among various manufacturers, I still think JF makes the best replica of Royal Oak 15400, even ZF made the same watch in recent days, it still can not be comapred with the one made by JF. Well, this timepiece has a Miyota based movement that has a noisy auto rotor, this is the only issue with the watch, but I do not see it is a big problem for this watch, Miyota movement has a high stability and accuracy, now many replica watches are using this movement.

AP Royal Oak 15400 Blue Dial

5. Noob GMT-Master II 116710BLNR

This GMT-Master II Rolex watch from Noob is very controversial, well, I have to admit that many customers will consider 116710BLNR when they want to buy a replica Rolex, and this watch occupies a large amount of sale among all Rolex replicas produced by Noob. So, this is the main reason why I put this GMT-Master II in the fifth position. This watch is equipped with a clone 3186 movement, which offers the same time, date and gmt setting as genuine watch, this is what most customers care about on a replica Rolex GMT-Master II, while Noob factory makes it correct. However, GMT-Master II is also the replica Rolex which I do not recommend to my clients, because the clone 3186 movement from Noob currently has a high repairing rate. Hope Noob will improve the stability of this movement in the future. If the movement becomes better and more stable, the watch will be the most sought after product in our market.

Noob V9 116710BLNR 904L

6. GF Avenger BlackBird

It is the best-selling Breitling watch in this year. GF has updated it to V4 version, for this Breitling watch, before I wrote a dedicated post to introduce it, you can read the review here. GF makes this replica with A2824 movement, absolutely you can buy one with real Swiss ETA 2824 from another factory. However, the quality from GF is the best, in my opinion. For people who love cool black watch, I recommend Avenger BlackBird, the watch comes with one black rubber strap, which feels very comfortable to wear, the big-size crown is also more convenient for you to rotate, although it uses an A2824 movement, the watch still has a high stability.

GF V4 Avenger BlackBird

7. V6 Ballon Bleu

In this top ten list, Cartier Ballon Bleu is the only one with round case, a lot of men are not willing to buy a Ballon Bleu wrist watch, maybe you guys do not think it deserves this position, however, I need to put it in this position, because Cartier Ballon Bleu is one of the wrist watches which are women’s favorite, and it accounts for a large share in women’s watches sales, so I think there should be a position for Ballon Bleu in this list. Besides, whether it is in 28mm, 33mm, 36mm or 42mm, Ballon Bleu can be equipped with a real Swiss movement. For example, if it is a Ballon Bleu in 28mm, then it has a Swiss quartz movement option, a 33mm or 36mm Ballon Bleu can be equipped with real Swiss ETA 2671 movement, this is the movement advantage of Cartier Ballon Bleu, but you can not find this advantage in other popular brands like IWC, Panerai, etc.

HBB V6 Ballon Bleu 36mm

8. VSF PAM 441

Panerai is one of the best-selling brands in our market, so I need to leave a position for it, while it is a truth that Panerai has a lot of models selling very well online, PAM 111, PAM 127, PAM 438, PAM 441, PAM 382, etc., these are all best sellers in Panerai collection, but there is only one position, I left it for PAM 441. A lot of people think that PAM 438 deserves this position more than PAM 441, actually both PAM 438 and 441 are the best-selling ceramic Panerai watches in our market, both watches are ceramic, PAM 438 has a ceramic band, while PAM 441 has a brown ASSO leather strap, in my opinion, the leather band can be more accepted by the public. By the way, PAM 441 from VS factory is equipped with a Super Clone P.9001 movement, which has balance wheel in correct position at 7:00 and offers genuine movement time setting.

VSF PAM 441

9. ZF Big Pilot Le Petit Prince

ZF has made a lot of popular models, especially in IWC area, the Portuguese 7 Days and Big Pilot made by ZF have a high quality, which has been recognized by many buyers. Too many good IWC models and I do not know which one should be ranked in this position, so here I choose the one which my blog readers mostly asked about, it is Big Pilot Le Petit Prince, reference IW500908, with blue dial. The latest version of this replica from ZF is V2, there are four places which men like on this watch, big size, charming blue dial, solid case back and real power reserve display, plus advanced watch-making technology, ZF makes it to be a very good replica, one of the must-have models for IWC watch fans.

ZF Big Pilot Le Petit Prince Blue

10. VSF Planet Ocean Deep Black

I almost forgot Omega, now until the last one, I remembered Omega should have a position in this top ten list. If you need an Omega watch, the only factory I suggest you buying from is VS, whether the Omega watch is Aqua Terra, De Ville or Planet Ocean, VS makes the best replicas of them. Too many replica Omega watches in good quality from VS factory, but there is only one position left, so I give it to this Planet Ocean Deep Black. Maybe a lot of other Seamaster watches with more common outlook are sold better than this Deep Black Planet Ocean, but this is a new face we saw in Planet Ocean collection in 2019, very rare ceramic case and dial, you will immediately recognize it among various Planet Ocean models, the replica is equipped with a clone 8906 movement, which features a black balance wheel like genuine, the rubber band is also in black, which is in line with the black color theme of the entire watch.

VSF Planet Ocean Deep Black

Except the ten watches above, there are many other replica watches that are sold very well, for example, Rolex Submariner No Date 114060, Datejust from ARF, Sea-Dweller Single Red 126600, Portuguese 7 Days Power Reserve from ZF, Royal Oak Diver 15703 from JF, Patek Philippe Aquanaut from ZF, etc., overall, 2019 is a big year for replica watches industry, and I think there will be more good quality replica watches published in future.

Audemars Piguet Royal Oak 15400 from J12 Factory, The Newest V5 Edition Arrives

Replica Audemars Piguet Royal Oak 15400

Royal Oak is one of the most popular sports watches, in my opinion, its popularity is second only to Hublot Big Bang. Among so many Royal Oak models, the most classic is 15400, the Royal Oak 15400 has a diameter of 41mm, which is not too large and very suitable for most men. Royal Oak 15400 also has several dial versions of black, blue, white and grey, here it is the one with grey dial.

JF Replica Audemars Piguet 15400
JF V5 Replica Audemars Piguet Royal Oak

Royal Oak 15400 has a very simple design, so it is always the hottest model for various watch manufacturers to replicate. However, after seeing so many replicas from different factories, the best one is made by J12 factory, we call it JF here. No other factories can compete with JF, which still continuously improves this watch, now this one is the latest V5 edition they just published several days ago, with a lot of improvement upon previous version.

First, open the clasp and check the “AUDEMARS PIGUET” engravings, they are more three-dimensional, the sand-finished background is more delicate. The “AP” engraving on the buckle looks more three-dimensional, and it has the same sanded texture as genuine watch. Third, the checkers on the grey dial have the same size as genuine, each checker is closer to that on genuine in size.

Audemars Piguet Stainless Steel Case

I never doubt the case finish of Audemars Piguet replica watches from J12 factory, because they never let me down. The case finish JF has done on their Audemars Piguet watches can be even compared with that of genuine Audemars Piguet, even the Rolex replica watches made by AR, which is a sub-factory of J12, have already inherited the exquisite manufacturing process from JF.

About the movement, it is a big advantage of JF. The 15400 is equipped with a clone 3120 movement, which is firstly developed by JF. Because the movement is modified on the basis of a genuine Miyota 9015, so it originally has a super accuracy and stability. The auto rotor and movement plates are decorated by JF according to genuine Audemars Piguet 3120 Calibre, check those sculptures on the auto rotor, they are very close to genuine movement, the jewels on movement plate also have correct color tone.

Having been updated to V5 edition, every detail on this replica 15400 has reached to be perfect. It is the best version, you do not need to wait and it is time to buy now.

When I saw this full gold timepiece, it is so bright to me, and it looks so good on dark or bright skin. The size 41mm*9.8mm case is made of 316L stainless steel, with gold coating, and the surface is brass very well, I like the brass pattern very much, and it is even better on the gold. I can see there are screws on the bezel to fix the whole piece together, this has become the typical machinery beauty of Royal Oak watch. Looking into the dial, which is special blue check design, quiet special on a full gold case. The stick markers and three hands are all in gold, which is luminous. Functions are including hour, minute, second and date, adjusting from the crown. There is engraving “AP” on this hexagonal crown. On top the front glass is made of sapphire crystal, wearable and colorless material.

We can see every replica detail through the clear back case. The bracelet is made of stainless steel and proceed with PVD gold as well. The Tang buckle is very elegant too, the “AP” logo looks as same as per original too. To conclude, this would be the best replica edition that I’ve seen, especially on the details and manufacture work.

Replica Audemars Piguet Royal Oak Jumbo 15400 Miyota 9015 Movement

Replica Audemars Piguet Royal Oak Watch

It is one of the best-selling replica watches now in the market, people who have ever bought replica watches before must have this Royal Oak Jumbo 15400 replica, because the watch is really a good one that has the best quality among all replica Audemars Piguet watches with sweeping seconds. The biggest advantage of this replica AP watch lies in its Miyota 9015 movement, which is genuine and directly imported from Japan. Check the movement testing result, it is only 2 seconds slower than other Automatic movements that are used on most replica watches currently.

Audemars Piguet 15400 Blue Dial

The case is 1:1 replicated from the genuine, it has the same construction as the genuine, bezel is locked down on the case through 8 screws. Each corner of edge of the case is polished round and smooth, while the front face is brushed to resist scratches. The dial is classic blue checkered. Clear index hour markers have steel edge around, while the central luminescence material is filled, the superlumed dial emits strong green light in the dark place. There are no other complex details on the dial, so that is the reason why so many simple replica watches could be replicated so close to genuine watches.
