Omega Crystal PX5000 for Seamaster 2576

As the title describes - seen gold tone ones online for around $45 but no silver tone tension rings. Perhaps I could but the gold tone one and reuse the old original tension ring?

It’s for this Seamaster, is currently has a signed omega crystal but it’s cracked! ☹️

If not I’d like to buy one of these crystals. Seem to not be stocked on any of the sites.

thanks Ollie
