Crystal help ref 166.002

I need help finding a new crystal for a 60s seamaster ref 166.002 with a cal 565 movement. I have found conflicting answers online about the part number, seeing in some places that it is the 063pz5056 but others say it is pz5123. Does anyone know the correct part number, or even the crystal diameter (I have calipers to measure, but that would require taking the crystal out of the case, which I’d prefer to only do once) so I can purchase the correct crystal? I’d prefer it to be a crystal with the omega logo in the center, but am fine without it and can do generic if it is cost prohibitive. Thanks for any help!

I should add that I have a ref 165.001 as well that I was able to find a generic crystal for and was able to replace that successfully; would the crystal for the 165.001 also fit the ref 166.002? Could I just buy another 165.001 crystal and use it on the 166.002?

No Omega Parts account but cousins gives following info for Omega 166.002:

Omega PZ5056 silver tension ring (PX5056 gold tension ring):
Overall diameter Ø31.62mm
Height 5.15mm

You can always use a generic crystal.
