In recent months, VS Factory has brought us a lot of new things, including the 100th Oyster Perpetual Rolex watch and the so-called free-sprung movements, but I do not think their 3235 and 4131 are true free-sprung movements.
Why the 3235 and 4131 are not true free-sprung? Please check the pictures below.
The picture above shows the new clone 3235 movement with free-sprung balance made by VS, the factory firstly installed this movement in the titanium Yacht-Master, later, they equipped this movement in their Datejust.
Although you do not find the extra regulator, but it is hidden below the balance cock.
Remove that balance cock, you can see the extra regulator hidden below, it is used to adjust the error.
The 4131 movement made by VS also has the same issue.
Are VS Factory able to develop the true free-sprung movements? I think they can, but in a short period they won’t, maybe the better true free-sprung movement will be their next move. However, the so-called free-sprung 3235 and 4131 from VS are meaningless, what is the purpose of VS to do so?
The dealers I have seen very clearly and honestly mark these as “free sprung effect”.
It’s just to make it look free sprung at first glance.
