THB Factory AP 15407 V3

About two weeks ago, THB published the V3 edition of the replica AP 15407, which now has a free-sprung balance. I have introduced the AP 15407 several times on my blog, first, it is the one made by ZF, then I introduced the V2 edition of 15407 made by THB in 2024, you can read the review about the THB V2 15407 at https://www.susanreviews.com/2024/09/26/thb-factory-replica-ap-15407/, now it has been almost two years later, THB published the V3, is this a signal that APS will be back soon? We all know their relationship. However, I suspect that the real factory behind this newly released V3 15407 may actually be ZF. In the past, THB has always the biggest seller of this AP watch. Now that APS has shut down, it seems unlikely that THB – being a branch of APS – could return to the market so quickly. Therefore, this new free-sprung 15407 may actually be a ZF release marketed under the THB name. You know, ZF has been very active in the AP field in recent months.

On the first replica of AP 15407, the balance wheel has a wrong position and it does not move. On the updated V2 edition of THB, the balance wheel is rotating. On this V3, we can see there are weights on the balance wheel. But the watches does not have a double balance wheel, it is a single balance wheel. I watched many video reviews about this watch, some claimed that a customization of adding a double balance wheel is possible and they charged a lot of money, I think it is not necessary to spend thousands of dollars to do this, not worthy. Besides the balance wheel, I think there is another flaw which the factory should pay attention to and correct it immediately, please check the two pictures below, the place marked with red triangle, the space between the bezel and the bottom line of the case. On genuine watch case, the space is not that wide.

VS Factory YachtMaster Titanium 226627 Free Sprung

Leave a reply

I already said that VS Factory will publish the free-sprung 3235 movement before in my last article at https://www.susanreviews.com/2026/06/08/two-big-news/, now the movement comes, but is it the true free-sprung 3235 movement? Everybody has different opinions about this, but I do not think it is a real free sprung movement, it does not have weights, just like the clone 4302 movement they developed for AP 15500 before.

Look at the clone 4302 movement from VS Factory, there are no weights on the balance wheel. To correct the inaccuracy, you still need to adjust that regulator I marked.

About the YachtMaster 226627 from VS, I introduced the Clean version at https://www.susanreviews.com/2025/05/26/clean-titanium-yachmaster-42mm-226627/, which was the best one at that time, after the closure of Clean, perhaps you guys do not know where to get the best one, actually ARF is a great choice.

How about the one with new free-sprung 3235 movement from VS? Please check its pictures below first.

VSF Free-Sprung 3235 — New VS Free-Sprung 3235 Movement

Genuine Rolex 3235 movement — Genuine Rolex 3235 Movement

At first glance, we can clearly see the new clone 3235 movement indeed lacks a regulator if you compare it with the old 3235 movement from VS. But if you compare the new clone 3235 movement with genuine Rolex 3235 movement, you will find the former does not have weights on the balance wheel. However, with a solid case back, people do not see the movement inside, that’s also the reason why a lot of people think it is no need to buy the free-sprung movement, because almost all Rolex models have solid case back.

After this 3235, I think VS will publish the free-sprung 4131, but I do not know when. For all DD series movements, the free-sprung movements published by VS factory in future will not feature weights.

QF Daytona Free-Sprung 4131 V5

Leave a reply

In the Rolex field, many factories have now released free-sprung balance movement, including QF, ERF, Rich, and others. Among these names, some are new to me, and honestly, I am not even sure whether they are newly established factories or just branches of some older factories.

For example, I previously talked about RG. It sounds like a new name, but it is actually operated by RC. RC’s business has really expanded quickly. Last year, their Day-Date became extremely popular across the whole market, and now they have successively released the Daytona and the GMT-Master models.

Alright, let’s come back to this Daytona from QF Factory.

QF Factory’s current marketing strategy is somewhat similar to what Noob Factory used to do. For almost every hot-selling model, they like to keep releasing new versions and create new selling points or gimmicks, but in reality, the actual upgrades are often not that significant.

For example, this 4131 Daytona is claimed to be the V5 version. This kind of naming easily gives people the impression that their Daytona is the best one on the market. However, in terms of overall workmanship, there is still a gap between QF and VS, not to mention compared with the previous Clean version.

Now QF has free-sprung versions of the 4131, 4132, and 3235 movements. In fact, for Rolex Datejust and Daytona models, it does not really matter that much whether you choose a free-sprung movement or not.

However, for some exhibition caseback models, such as the Le Mans Daytona and the newly released Daytona in 2026, you can choose the version with the free-sprung movement. And in the current market, it seems that QF is the only factory making a Daytona with the free-sprung 4132 movement.

Rolex Daytona 4131 Free Sprung Case Back

Two big news

Leave a reply

I have learned from some suppliers in the watch market that APS will be back. If this is true, that will be too good. But the bad news is Victory Factory(VF) may never be back to this business. I explained the connection between VF and APS in post at https://www.susanreviews.com/2026/05/15/want-to-sell-this-blog/, but VF makes Rolex replicas, that’s the big problem, and the watch parts of their Rolex replicas are made by the same parts suppliers as Clean, and Clean Factory’s thing is not over yet, so you would imagine what happened next.

Not sure when APS will be back, or they have been back? ZF already got the 4302 free-sprung movement and 4401 free-sprung movement that were owned by APS before, now everybody knows they can buy good quality replicas of AP 15500 and AP 26240 from ZF. What watches APS will bring to us if they back, Rolex?

Another good news is VS Factory will bring two new movements, which are free-sprung 3235 and free-sprung 4131.

There are many factories manufacturing Rolex replicas with free-sprung movement, such as QF, ERF, Rich, etc. Among them, QF is the one with the most potential. About the free-sprung 3235 which VS will bring to us soon, I advise you not to expect too much. Because last time the 4302 they adopted in the AP 15500 is not a true free-sprung movement, because it does not have weights. I am not sure if the free-sprung 3235 and 4131 from them will have the weights on the balance wheel.

ZF 15500 Free-Sprung 4302

Leave a reply

It’s been a long time since we last heard from ZF in the replica Audemars Piguet space. The last time ZF made waves in the AP replica market was a few years ago with their widely popular AP 15400. However, after APS released the super clone 3120 movement, ZF was thoroughly outperformed. In the years that followed, there was almost no news from ZF in the AP replica field. Meanwhile, APS thrived and essentially dominated the entire high-end AP replica market. Unfortunately, APS was shut down last month after being hit by a crackdown. Now, this could be ZF’s only chance for a comeback.

The watch is ZF’s latest 15500, equipped with a free-sprung 4302 movement. Could it be that ZF has directly taken over APS’s free-sprung 4302 movement? After all, this movement was first introduced by APS. A few months ago, facing competition from VS, APS rushed to release a free-sprung 4303 movement. Now that ZF has taken over the free-sprung 4302 movement, just heard that ZF has also taken over the super clone 4401 movement that was owned by APS before. The question is whether they can also take over APS’s super clone movements in IWC replicas.
