Clarification on White gold within 6263 / 6265 dials

[Jgreenfield]

Hi all,

Had a question I haven't been able to get full clarity on, regarding vintage 4-digit Daytonas / Cosmographs dials.

Are the coveted Sigma dials on stainless models exclusively indicative of white gold indices or do some non-sigma dial 6263/6265 Cosmographs / Daytonas feature white gold indices as well?

I ask primarily because it is difficult for me to actually tell the difference between the white gold indices (on sigma dial Daytona’s) and the presumably stainless indices on non-sigma dial 6263/6265 Daytona dials...it’s as if the stainless and the white gold age very similarly, but I may just not be a savvy / acute enough collector.

Would love to know from the experts on here, very curious about this point.
Also a follow up if I may - does the sigma dial denote that the hands are also solid white gold or just the hour indices? How about the Rolex logo? Purely curious.

Many thanks! 🙏
