This dial looks to me if it belongs to another case. This is a supercompressor case and as far as I know the dial must be a Sherpa then. This dial seems from a Ocean Pearl.
I think that you can't rate the logo based on a single photo (but I admit, it looks a bit strange). And from my point of view it doesn't make sense to change anything on the dial of such a simple watch.
The dial in a supercompressor case does not necessarily have to be marked with Sherpa:
You’re right, but the Supertest versions are a bit of a exception I guess. But still my guess would be that the dial belongs not to this case, hands I’m not sure of. Vintage Enicar is a real mine field these days. And I don’t think that someone messed with the logo, I think it shows just some wear. The logo is applied and it is very hard to mimick this. This dial has clearly the applied Saturn logo, seems original to me.
