If I have a watch with the 6P24-00A black and white moon phase disc, can the disc be changed for the 6P24-00W blue and yellow version?

I am pretty sure you can change the disc to the other color but I don’t think they will sell that as an individual part. The movement is already so cheap, you can just buy the other movement color and swap the discs. Better yet, just replace the entire movement, that should be easier.
