How does Omega print wave dials?

Just purchased a Peter Blake 2254. Absolutely love it and one of my favorite parts is the wave dial. Looking at the dial, the waves definitely seem 3D, but the printing doesn't seem to dip into the waves. The newer, ceramic dials are flat where the printing is, as the waves stop and leave a "plateau" for the printing. Is the printing just thick enough that it flows into the grooves? are the grooves illusory (just matte, vs. gloss?). Perhaps a clear coat over the wave-grooves and then printed? Perhaps the same process to print over the concentric circles on a speedy sub-dial?

Obviously not looking to get into trade secrets or start my own dial manufacturing business, but genuinely interested on how Omega pulls this off.

The ceramic is likely molded that way. It could be laser etched as well, but I doubt the floor around the raised waves would be as even.

As far as printing goes, it's probably pad printing. It might even be jet printed, similar to your inkjet printer. They have a lot of time and money, you see...
