I will say this:
Patek removed a date to celebrate 50 years of the Nautilus; UN decided to create a 511-part time only watch that you correctly say looks like a spaceship to celebrate 25 years of one of the most groundbreaking watches of this century.
Absurd on all counts including the price, which is exactly what I would expect for a big birthday.
All the live photos I've seen of it have made me believe that it must be monumental in real life. Whilst the metal used for the case could easily have been something slightly more modern, the case design is outstanding when viewed as a package with the movement, dial side.
I personally think it's a fitting tribute to the original concept and a major step forward for the flagship line of the company.
Thanks! Baruch
