I had this in for a rehaut polish and a gasket change a while ago. This is the 11 series of course but I had to use a 2.5mm gasket on this Clean 116713LN to get the magnification right.

There is one solution in the post immediately above yours. Personally I keep an assortment of gaskets on hand and pick the one that produces the best level of date magnification as the first priority with crystal sitting height as a close second goal.
Which crystal gasket should I use?

Very nice bro!I had this in for a rehaut polish and a gasket change a while ago. This is the 11 series of course but I had to use a 2.5mm gasket on this Clean 116713LN to get the magnification right.
Sorry, I wasn’t expressing myself very precisely. By „fitting the right gasket“ I actually meant the issue described by some that the clean gasket spec is different compared to gen spec. Not only height wise, but also concerning the diameter and thus altering the fit and compression of the retaining ring. Or was that a V1 issue and now you can install gen gaskets plug & play?
Ok all the tools are arrive and currently in progress
1. successfully removed original crystal
2. installed new deep crystal with 2.5mm gasket
3. confirmed that second hand is touching the crystal
4. cannot press crystal retaining ring.
I tried to press the ring with DJ36 bezel but since the press tool is cheap tool,
its not giving even pressure and keep pushing only one side.
I may try with bench vise or find better bezel.

3. Did you mean second hand is NOT touching your crystal?
4. If you try with a bench vise use appropriate stacking of pieces to make sure everything is protected. Taping some of the stack parts together make it easier to place them in the vise opening and start getting the jaws closed enough to hold everything.

Ack, you could try a taller gasket if that wouldn't make the date too big, Even make a custom height one if you only need a little bit of clearance.Second hand IS touching crystal. I need to shave it down
Started to fix date-mag, but ended up focusing height of crystal like gen.
used Deep Crystal V2 + 2.5mm Clack Gasket.
Huge Thanks to @KJ2020 !!
Today, I tried 2.7mm gasket.
Weird thing is that the installed height is almost identical...
I also compared 2.5mm and 2.7mm gasket before install and I confirmed that their height is different.
I see why @KJ2020 told to prep multiple gaskets and try to find best combination.
Now, I like 2.7mm gasket better and gonna stick with 2.7mm since its gen height

Stunning! I am also going that route as I have the gen parts (but no rep yet).My full franken with gen new 2xA/R crystal with 2.70 gasket. Height and magnification are perfect, gen like! (all obviously shared during the construction phase with the Master kj2020
May I ask if your build was tested for WR?

Did you or anyone else here try it out, whether a DJ36 crystal works well?
And, more importantly, does anyone have a way to source VSF parts or crystals in particular? I've only got word from 2-3 TD's which say super hard / virtually not possible.

I had chance to compare with stock CF
Left : Deep Crystal V2 + 2.7mm gasket + Xing Bezel
Right : Stock CF V3
Left : Deep Crystal V2 + 2.7mm gasket + Xing Bezel
Right : Stock CF V3
It could be the lighting, but looking at these photos I'm having a hard time seeing any difference in clarity between the Deep and the stock crystal.
I knew CF crystal's clarity is pretty good and I have no problem with that.
However, my main goal of changing crystal is to have correct height and date mag, not clarity
Agreed. But CF has had a reputation of using slightly "milky" crystals - it's interesting to see a comparison with Deep in equal lighting .I knew CF crystal's clarity is pretty good and I have no problem with that.
