I received my DIF today and having both watches side by side i post here my personal review compared to my ZF :
1. Overall look :
Both watches look and fell almost identical at first glance. The bezel on the DIF is stiffer and difficult to move.
The DIF has a newer serial number than the ZF and the bracelet engraving on the ZF is smaller and deeper.
2. The movement :
Both watches use the same movement but the DIF has no ghost date position like the ZF.
The both have different movement fixing points in the case, therefore a movement swap between these two watches is not possible.
3. Bracelet :
Overall the ZF bracelet has a better feeling than the DIF and also sits better on the case.
The lugs are not well aligned and flush with the case .
The brushing on the ZF is much better then on the DIF.
4. Case :
The finish and polish is on both watches identical besides the lug points are better on the ZF, the DIF ones are not even .
5. Crystal :
The crystal on the ZF has a better haptic like there is an coating on the outside, it doesn’t catch fingerprints like the DIF crystal.
The ZF crystal is 1mm higher an is more domed the the DIF.
6. Dial :
For me the most annoying thing on the ZF is the fact that the hands and dial markers have different lume color which is pretty noticeable.
The lume color on the DIF is the same color on hands and dial markers. Also the printing on the dial is more white and not silver grey like on the ZF.
Conclusion :
DIF did a pretty good job on this model for a new factory. For me the only noticeable difference between these two watches is the lume color which bothers me.
I’m gonna stick with the DIF and i’m gonna swap the crystal from the ZF.
Thx
