Omega PZ5072 Crystal

I'm looking for an original Omega PZ5072 crystal. This would be the version with the stainless steel tension ring, which I would also need.

I have a 166.020 SMDV in really good condition, but unfortunately without the original crystal. It's not a big deal, but if I can find one, it'd bring me peace. Prices on eBay are absolutely bonkers, so I'm hoping someone here has a spare one and is willing to part with it for a reasonable price.

Still looking.

@omegawatchlover thanks for taking a look. $100 is hard to justify. I'll rather keep the generic I have and wait in case someone has a spare one for sale.

In the UK a genuine crystal from an Omega watchmaker costs around £50 so I think on the secondary market it will be tough to find them much less.
