Seiko Presage enamel dials, are acknowledged by Seiko to have rough surface (apart from dimples which are normal).
Arita Porcelain dials also have color unevenness as acknowledged by Seiko. Arita dials are also substantially thicker by virtue of their process.
I have had the opportunity to examine a Richard Lange PLM enamel and the Seiko enamel Presages under the loupe and the difference in quality is very perceptible. This is to be naturally expected and quite acceptable as well given the very attractive price point at which the Presage enamels are offered.
To that extent they lack the near-perfection achieved by A.Lange & Sohne or a couple of marquees.

Base metal for the Enamel Dial
By: chintu : May 22nd, 2021-10:25
A very interesting horological tidbit. Romain Gauthier in a recent interview ( yesterday on youtube “in the metal”) spoke of the complexity of making enamel dials and how factors such as the color mixing and layering as well as temperature plays a crucial...

Base dial metal can be Gold, Silver or Copper. There may be alloys, but the three represent the preferred metals for their properties. That it is enamelled on both sides is also confirmed. This is known as “contre èmaillage” ( counter enamelling) when the...

. All the old pocket watches with enamel dials probably don't have base gold dials. Think about all those old road or advertising signs. Le Creuset enamel ware is cast iron. Just have to match the glass to the base material. -John

Watch dials have to be without any blemish or even a speck of trapped dust or bubbles and are unimaginably thin, besides the color having to be exact and uniform. The dials cannot have any camber or even the mildest un-evenness across the entire surface. ...

Any enameled product, regardless of the base material metal, has to be meticulously cleaned of all oil, dirt and debris for the vitreous enamel to adhere. If any of the enameling doesn't adhere to the base material and there are pockets or voids, it is ve...

there would be no basis for an enamel watch dial alone to command an extra price of $20k while an enamelled cast iron cookware costs $100 and an enamelled pen circa $1000. And so it goes...where a Faberge egg would cost astronomical sums. If enamelling wa...
Perhaps...yes

I cannot hazard a guess at this stage. For now I tend to believe that enamel dials are complex from multiple perspectives, the build-process, the physical attributes once finished, the decorative artwork incorporated into the dial etc; all of which elevat...
