Tritium dial/hand replacement for Luminova on El Primeros possible from factory?

  • Mates,
    if an El Primero from the 1990'a or 2000's would need a dial/hand replacement form Tritium to Luminova, would Zenith do this? Do they usually have replacement dials with Luminova? (I'm thinking about models like the Rainbow/Flyback, Class, or Prime HW-models, and others).
    Thank you for chiming in!
    Regards,
    Robert
