Great technical question!
Welcome to the site!
We have some superb qualitative and technical answers by some of the other members of the forum.
I too personally like the design of the 5197 more, but I do agree the 5177's caliber is the more desirable caliber.
Considering that you want an automatic caliber, have you considered the 5140 (another forum member recommended this already).
Pros: It is beautifully thin, automatic, looks great, has a small seconds subdial (which I prefer due to the large seconds creating too much movement on the dial), comes in both guilloche dial and enamel dial. Reasonable 46-hour power reserve. Big watch, very legible and great 40mm size.
Cons: It doesn't have date, it has a nicely finished movement, but the movement is not visible through the back, solid gold case-back.
Here's another post about the Breguet 5140 from 2008.
Keep us informed of which one you get!

I have been contemplating on obtaining a 3-hander from the classique collection and have been drawn to the 5177(caliber 777Q) and 5197(caliber 591A) in white gold. My understanding is that caliber 591A has the balance spring made of silicon as opposed to ...
You can't go wrong with any of them.
You have two very nice expressions of Breguet Classicism, even if I would have preferred WITHOUT date... As for the Calibre, does the silicon spring represent an advantage, compared to a Classic one? I am not sure watchmakers agree on that. Some say yes, ...
I say both are winners
Technically I can't really say but both have strong appeal. You can't go wrong with either. Please let us know what you finally chose. Bill
Well, they are quite different movements.
The calibers are very different. The 591 is based on the Lemania 8810 which is based itself on the Longines 990. The low power reserve is not a true problem since the double barrel improves the thrust. The 777Q is a more contemporary caliber and I prefer ...

About the power reserve ...
The "the PR is only 38 hours and seems too little for two barrels" you should consider that on this caliber, that is considered by many as one of the best ten calibers ever made, the two barrels are there not to increase the power reserve but to balance t...
