I've had a VAC modded (Lume dial, hands, and AR) for some time. Bought it M2M a year or so ago. It is definitely one of my favorite watches. The problem when something makes it to your favorites list is that you start to notice flaws even more. None of you out there with your beautiful 3717 builds helped the situation either.
For some reason the VAC AR wasn't for me. It's very good but it has a blue tint, which I know is gen like, but just never seemed clear enough. I happen to be an AR freak and when it comes to AR for black dial watches, Taka is as good as anyone.
At some point I picked up a Taka AR crystal from a split up M2M sale. It sat and sat. I finally pulled the trigger and bought the gen dial and it came today so it was project time.
First off, check out the difference between the Taka (left) AR tint which is yellow/green and VAC (right) which is blue. When the crystals are just sitting there the yellow/green looks worse to me but once assembled on a black dial watch, the crystal completely vanished. It's soooo good.
Next was a dial swap. I must say the gen (left) dial really doesn't seem to be much different at all. Other than the flat Lume markers, it's really hard to tell the difference. This is in contrast to Gen Omega dials that make the rep Omega dials look like a turd when you compare them.
Next was assembly. Gen on the right now:
Finally finished. I couldn't be happier with the way it turned out. The gen dial with the Taka crystal is just stunning. One of my favorite all time watches.
