PPF is ZF.

At the beginning of this month, PPF announced that it would introduce modifications to two popular models: the Patek Philippe Nautilus 5712 and the Vacheron Constantin Overseas 4500V. Both watches are highly sought-after, particularly the Nautilus 5712, which has been a bestseller in recent years. The enhancements for both models have now been completed, and the following sections will outline the specific improvements made.

Firstly, the Patek Philippe Nautilus 5712. Prior to these updates, the model was in its V3 edition, and it remains so after the enhancements. Two previous improvements were made: on the V2 edition, the power reserve indicator became functional, and on the V3 edition, the clasp was updated. Recently, PPF introduced another significant improvement to the movement by deepening the engravings of the golden lettering. A comparison of the older and newer versions reveals that the lettering on the older version appears printed, whereas the newer version features engraved lettering with noticeable depth.

Secondly, the Vacheron Constantin Overseas 4500V underwent changes primarily to its movement. Specifically, the balance wheel's position was adjusted to approximately the 7 o'clock mark, closer to the 8 o'clock position. This modification resulted in an increase in case thickness from 11.2mm to 11.5mm. Additionally, the date adjustment mechanism was altered; on the V1 edition, rotating the crown clockwise adjusted the date, while on the V2 edition, counterclockwise rotation is required. Some individuals have noted that the date font appears thicker on the V2 edition, though this difference may not be immediately apparent.
