·When did Omega introduce Omega labelled crystals? Is there really any benefit over a generic crystal? Or is just part of Omegas constraint on availability of parts?

I have an early Seamaster Calendar with a signed crystal. Serial number 13.0M from about 1953.
I would have expected a domed crown....
Ah. I'm currently wearing an International piece and if this domed crown isn't original, I'll be very surprised.
