Among classic watches available today; what is your favorite watch that has both a perpetual calendar and a chronograph?
The usual suspects are (feel free to add your own as long as it is a currently available model)...



Which one do you like?
Why do you like it so much?
Which one do you think is more technically sophisticated?
What attribute do you usually value the most?
I do know that I posted this in the A. Lange & Sohne forum and thus might be biased.

But I've got to say, I find that Vacheron Constantin dial to be very beautiful; especially with the engraved moonphase. I suppose that if this Vacheron Constantin watch did not have this particular carved moonphase, I would like it far less.
The Patek Philippe definitely has the nicest case out of all three; the concave bezel and the fluted lugs are fantastic. Patek Philippe 5970 owners should avoid polishing their cases because this will destroy the fine fluted lugs and you won't see the tiered lugs after a substantial polishing.
The Dato/Perpetual is really thick. It is probably the thickest of the three, and the moonphase is very small. But the movement is wonderful on this piece.
but frankly because it doesnt have a 12 hour counter, nor does any chrono perp cal watch there is on the market just yet, none of them pass my test!
But those are some good watches to own, if only i had the money!
Thanks for the post!

is my current favourite...

-minimal 'excess' information
-'ALMOST' flawless performance (The instant jump does NOT happen PRECISELY at midnight...)
-beautiful case design
-right heft
Ok, reliability could leave a bit to be desired but this would have to be one of my all time favourite...
