Was the 16660 SD ever made with a matt dial with White Gold surrounding the Indeces?

[Stratton]

There was a Triple 6 Sea Dweller recently sold on an auction site that was advertised as having an original matt dial with WG Surrounds around the indeces and I wondered if this dial was made by Rolex or could it have been a glossy dial faded to matt? There is also a similar dial on its own currently advertised with the claim that they were made for a few months only. Were they ever made? Thanks in advance for your replies.
