Looks like a dial to me (tools in comments)
Here is my latest try to make an enamel dial. This time I tried wet packing on the front side. It takes significantly longer time. The counter-enamel was applied with enamel glue. The biggest difference is that the total thickness is now 0.7 mm. starting from a 0.3 mm copper disc and 3 layers of enamel: a counter-enamel, a wet-packing layer, and a finishing layer (sifting). I still can't figure out how to protect the edge from oxidation. It's much better with using wet packing technique but it is there. Tbh, it's visible much more on the video and pictures than irl. I think I am ready to make a dial I actually want! I just need to figure out how to fix dial feet.
