It has landed, and it has me baffled! The dial is out of this world in terms of finishing and aesthetic.
The - slightly course - sunburst is lilac-grey and the dial features a circularly finished outer ring that is not applied, like I had envisioned, but in fact just finished differently to the rest of the dial. You can tell by the fact that there is no height difference to the center (or the outer edge, for that matter, which shows the original finish protruding past the ring with circular finish). The markers are applied.
I'd be very happy if someone can provide me with reference material, like having owned similar examples or period catalogs.
Also, how would I go about dating it?
