PPF is ZF.
At the beginning of this month, PPF announced that they will make some changes on two watches, one is Nautilus 5712, the other is Overseas 4500V, both are very popular models, especially the Nautilus 5712, which has been a best seller in recent years. Now, improvements on both watches are completed, in the following I will show you what improvements have been made on both.
First, the Patek Philippe Nautilus 5712. Before this improvement, it is V3 edition, after that, it is still V3. On this watch, previously two improvements have been made, on V2, the power reserve becomes real. On V3, the clasp was changed. Now, PPF made another important improvement on the movement, whose golden engravings become deeper, please check the comparison pictures. I put two movements together to make a comparison, it is easy to tell. On the older version, the golden letterings seem to be printed, while on the newer version, they are engraved, there are obvious depth.


Second, the Vacheron Constantin Overseas 4500V. The improvement also made on the movement, its balance wheel is changed to the position of 7 o’clock, actually very close to position of 8 o’clock, you can see the pictures of V1 and V2 below. However, after the change on the movement, the case thickness increases from 11.2mm to 11.5mm. Besides, the date adjustment also changes, on previous V1, rotate the crown clockwise, the date will change. While on the V2 edition, you need to rotate the crown counterclockwise to adjust the date. Some people said the date font becomes thicker on V2, I did not notice the difference.
