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.
