You haven’t seen it because it doesn’t exist. It has been refinished without a doubt. That looks like a minute track from an 1803 track dial. Don’t you find it suspect that the hour markers cover some of the numbers on the minute track? Clearly a refinisher had a printing plate and just reused it. The font is also all wrong.
Unfortunately, you’ll be looking for likely a long time. Parts for this model watches rarely pop up. There was a poster from a few years ago who needed a bezel and I think it took him a few years before one popped up on ebay. The only dial that I ever saw separately come up for sale (in the 3-4 years I’ve kept an eye on these) sold a few months ago and I bought it for a project.
A better refinish isn’t really a great prospect. You’ll probably have to pay a refinisher $350+/- to make a custom plate for this dial and reprint. After all that, results will vary and you might not like the final result.
In the short term, your best bet is buying a project watch to make one good watch or selling this one and buying another. Otherwise, you’ll have to play the waiting game. But be careful as there were a few sellers online selling fake parts for these.
