Here is what the seller replied to my question about the dial (I would appreciate your opinion on what this means to the value of the watch):
"All parts of the watch are original. The dial is also the original dial, and it's a new coating on the dial, that means: The old lacquer
was professionaly removed and smoothly coated a new UV-protective lacquer on the original dial. This was made by the manufacturer, who produces the dials for the Swiss manufactures (VC, JLC, IWC).
The indices, hands and colorcoating were not touched."
