left are ZZFV3 and right are Noob V12. Noob dial.is slightly darker green. Bracelet of noob clasp are better made especially the close hatch with less sharp edge. SEL of Noob , surprisingly is better. But ZZF bracelet feels more substantial.
The differences between both watches are very minor. Unless u place both watches together. It's very difficult to pick out the minor thing.
I will say the rep industries has reach a stage where, Rolex rep can almost match the gen 95%. Unlike 10 years ago, where Rolex sub rep has so much flaw despite the price that time was much cheaper compare to now.
You wouldn't go wrong with ZZF V3 or Noob V12 but with better bezel click and SEL, for me, I will pick the Noob one.
