I had both, but sold my White dialed Rayto Zenith and bought the Black Dialed Dayto Rolex.
I compared both Black and White Dayto Zenith and Rolex, and I just got that The White Dial Zenith is more appealing than the new White Dial.
The old is thinner , nicer, the contrast between the white dial and the black circeld couters is maginficient, much more than the Grey used on the new..
For the Black, I prefer the new one to the old one...
Her's a pic or 2 of my Beast...
Best.
