Thanks for posting these.
On the first dial, it is neat to see how the step on the front is evident on the back too. I suppose that the dial was pressed or struck into this form.
On the second dial, both the glossy surface and reflective/metallic printing are striking. Also, I wonder if the black galvanic coating was applied first, and then scratched off in order to solder the hour markers and emblem.
On the third dial, I wonder if the golden sections, in between the hour markers, are embossed rather than applied. Also, I am intrigued that the reverse is not black. Maybe the black on the front was not applied using a galvanic process.
