Case ref. 14730 crystal sourcing, PZ5072 multiple versions?

Hello, I'm currently having trouble sourcing a crystal for an Omega Seamaster case ref. 14730 and would really appreciate some help. I previously bought a generic PZ5072 from CousinsUK but found that this was at least 1 mm taller than the original crystal and leaves a significant gap in the case when assembled. I believe I have a Sternkreuz XAC316597 which is at the link here: https://www.cousinsuk.com/sku/detai...s/xac316597?skuId=2006&productCategoryId=2208.

Are there alternate versions of the PZ5072 crystal with different heights? I'm confused that a "standard" part has so much variance. I also have a companion post on watchrepairtalk found here: https://www.watchrepairtalk.com/topic/35522-sourcing-pz5072-for-omega-seamaster/. My guess is that the use of a screwed in movement ring means that the taller crystal can't fit.

Any help would be appreciated! I am open to buying any crystal that fits, generic or authentic, but would like to confirm that the crystal is the correct height before pulling the trigger.

The cousins crystal is 5.3 mm tall. The one I have is 4.36 mm.

I'm not crazy to think that PZ5072 is the correct part number though right? The catalogue even says it in the image here:

Any suggestions on what I can do? My thought is that I might be able to purchase a different generic omega crystal (either the PZ5005 or the G22741 from Cousins) which are listed as shorter in height.

I don't think there are many other options as the official source directs me to the incorrect part number.
