I agree with your opinion on all three references.
For me personally the top is the 5170G, because as you said, it’s the most mature and restrained with the punch for the trained eye.
For me it’s the watch that when in your wrist, makes you fit in every environment!
I risk to say, that it might be my exit watch because it matches my personality, for the exact same reasons you mentioned!.
Noticed the fancy six above the twelve o’clock numeral?
Just beautiful, and the the Breguet numerals, pure Patek DNA.
Thanks for the great comparison, enjoy them all in the best of health...
