Agree on the open dialed.
They are really too busy IMHO. The traditional ones are way better (also, of course, IMHO) even if I would have liked them more without the day/month cutouts (in this case I like the solution used in the openworked dials more).
I do like port holes/cuts a lot, actually.
If you bear in mind what Patek's and also VC's "super complications" look like and how big they are in terms of diametrer and thickness, then this offering from AP is the best one of them.
Superb. And keep in mind these new releases go back many years.
AP always plans 5-10 years in advance.
Well done AP
A mechanical masterpiece and strategically well placed to boost the Code 11.59 series.
