What crystal ring are you referring to???

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?

I'm in the same situation. I have a Pepsi CF GMT V3 and got myself a gen crystal. I took it to a watch maker who told me it won't fit. I didn't ask him if he tried the CF gasket or the gen one (not sure the gasket was in the package, but I think so).

If I understand your other post correctly, I should find a 3.1 mm or a 2.85mm gasket for the gen crystal?

I have had the best luck using a 2.7mm gasket with the gen crystal. Seems to have the most accurate date magnification to me.

What about the concern that it won't fit? And where should I look for gaskets? Ebay?

Esslinger or Cousins UK, buy 1 from each if you are concerned about fitment.

I'm planning to use a sub 40mm VSF crystal. Please advice gasket brand and height to achieve 2.5x magnification.

I have a gen crystal, bezel, click spring, hytrel ring, and insert on the way. Just bought a 2.7mm gasket in hopes that it will complete the install. Can't wait!

I was able to swap the crystal on my VSF sub to a deep xtal. The only problem is that once I press down the metal retaining ring, the crystal is not tight (it can spin clockwise or counterclockwise freely). The ring is pressed all the way down to the flange of the case. What am I doing wrong here?

Thanks so so much for any assistance

Usually that’s only an issue until you install the ring around the crystal/gasket. Gasket may be too thin or compressed. I’d try a new gasket. Order a few sizes for trial and error. It’s a tedious process and can be frustrating, but you’ll get it.
