The Duometre in White Gold is here:

question is interesting, my friend.
That us exactly why some brands like Panerai have such a strong success: an exrememly legible dial.
I guess it is sadly very personal, so will be albe to read the Duometre dial without any problem, others not.
When I saw the black dialed version, actually, I found it more legible than the platinum, but once again, I don't have any problem in reading the time on a Duometre, AND, when you have such a watch on the wrist, do you still look at the Time or do you Admire the Time?
I think it will depend on your ocular problems...Sadly.
Best,
Nicolas
