Hi! Jumping on this thread, to give my humble opinion on blue dials.
I have both APSF and ZF, and talking ONLY about the blue dial, in real life on sunlight there is no comparison between both. Both are different from Gen of course, but ZF as more sunburst and the APSF is almost mat. I tried to do picture but at home with Classic light is not ideal and I was not able to capture the différence properly.
I think ZF is more AP accurate with the sunburst, anyone who knows AP, know that there is something wrong about APSF dial. Unfortunatly I have not been able to compare with Gen, and last 15500 blue dial gen I ve seen was 5 years ago and can’t remember exactly what blue it was. And of course, no need to compare to internet pictures as AP are totally different in real life.
I ordered a SW dial to see it in real life, I think it is really to dark like midnight blue, very close to the 16202 or the 15202 special edition pre anniversary with the « bleu nuit » dial which was not the same as the actual color on 15510. I will swap it on my APSF (which has been modded by the best, and it is perfect except the dial) as I can’t wear it with the APSF dial. I know it is different from Gen, but even, for people who knows/own AP it is definitely more AP style. And if I don’t like I will put the ZF dial.
Thanks for reading my big block
, Hope it will help!
