5711a or 5712a if buying used and same price?

I guess it’s partly to do with the seconds hand jitter, with 28.8k being almost imperceptible, but you can drop to 18k with sub-dial seconds, since the small steps make even its sweep seem smooth.

Your Bovet icon uses 21600? Your other icon Moser is 18000!!!

Yes, as stated in my quoted reply, there’s no benefit from running at 28.8k on a seconds sub-dial, as the steps are so small compared to when a centre seconds design is employed, resulting in a smooth sweep and extending the power reserve.
The Moser centre seconds are 21.6k, btw.
When you were checking out the Bovet specs, did you happen to notice they offer a 5 year warranty too? That’s a point more worthy of raising than the sweep smoothness.

Nothing per se, but it's the entry-level PP movement, and not terribly exciting (to me). I have a 5146 which has this movement. I think the 240 movement is a bit more interesting.

I'm interested to understand what you consider makes a movement entry level when complications are added as modules to a base movement.
Vph? Number of parts? Something else?

Clearly the 5711 uses the base version of the 324 and the 5712 uses a 240 with added complications- that isn't an argument for one base movement or the other being entry level.
If you want the complications it is of course paramount to have the added modules - 5726 takes it up a further stage again with an annual calendar using 324 movement.

I agree, happy to see 240 movements used in grand complications i think its the thin profile that wins it for me.

It's the elegance of the overall architecture of the movement. The recessed micro-rotor is what does it for me.

I can agree with that - it is super elegant.

Agreed, really wish I had one on mine.

I found most PPmovements to be be pretty pedestrian...do the job but definately don't bother with a loupe

5711 for me as I prefer the higher water resistance on 5711.

you go diving in a 5711

In any other situation the functional difference is just an abstract thought experiment.

For example during hotel stay, I would rather wear it than keep it the hotel safe.
