Indeed, there was a version with
satine or satin-finish. Here is a catalogue image from 1966.
I share your concern with the smooth, mirror polished versions. Although I have never directly examined one, the few hi-res photos I've seen also show signs of over-polishing on the lugs and I suspect they have been refinished.
Edit: I had a peek at the discussion over at Orologi & Passioni and, aside from all of the wonderful vintage watches showcased, was reminded of the Patek models which shared this case design with V&C's 6394, although with a polished rather than textured finish. Ref 2551 was mentioned, and I can add that PP also used the same case for Ref 3433.
