It really is about the bracelet or strap fitment.
It is definitely feels more substantial than the 5712 on the wrist. Whether that is a negative or a positive is user based. I immediately felt the difference when I put it on. I think I am also wearing the 5726 “1/2 link tighter” than when I resized my bracelet for the 5712.
I don’t believe there are 1/2 links, but from what I recall I have it a little tighter. I’m guessing The 5712 allows for a looser fit and still feel pretty comfortable.
For context I wear the platinum Datograph without the deployant and it feels fine.
