working based off this gen for finishes. If it works, I'm sure they will become available...
Need to get a slightly satin lacquer but one that is really flat with no texture. There should be almost no step up or down for the track (from pictures I've seen). This makes sense when you read about how gilt dials were made, the brass was polished and then masked before blacking covered everything except the masked areas.
One of the reasons we are experimenting with blacking rather than paint is that it is a really thin, even layer, so the etching can be controlled to just go through the black. It give a really deep vintage look as well, dark grey to black depending on how the light catches it.
Another thing - where does the puffy lume above the surface come from? Most good condition ones I've seen photos of have the lume flush, or even slightly concave. Did the puffy lume above the surface come from a relume where they just laid it on top? I've done both in the past, easy enough to build it up..
I'm also experimenting with different size lume as it doesn't look that smooth, 50 and 10 micron lume mixed seems to give a good look...
Hi, I've searched for a long time to learn more about Rolex Gilt process. It was a very instructive journey indeed.
Check this topic:

Looking closer to gen pics, you'll see that Rolex Gilt has a negative recess:
their galvanic black coating was quite thick indeed.
My guess: they were using a mix of Zinc and Nickel, Zinc is known to produce quite thick plating, also this formula can explain the brown tints on tropical dials, brass oxydation mixing with other metals.
This plating is no more available nowadays, must probably restricted for environmental and safety reasons.
Another point: recesses were stamp pressed, so the dial would look better if you can slightly soften the edges of recesses.
Here is an old photo:
