Gen crystal for PO 42 DG4813?

[Guest machineboy]

Hi, I have a surprisingly nice PO 42mm with the DG4813 movement that looks and works very well (hell, even the crown screws down without hassle)! However, the crystal har AR that looks pretty bad and scratches when you just look at the watch. After wearing it one day it had noticeable scratches along the top of the crystal, without me bumping into anything.

 

I've heard that the sunnydale crystals are good replacements, but he has sold all of them.

 

I'm therefore thinking of buying a gen crystal from cousins. Does anyone know if it will fit perfectly on this model?

 

This is the model:
