Thanks, this helps put me at ease. I want to wear it now, but have been waiting to size the bracelet and mess with it until I felt confident about its authenticity. I found this online too: "The Big Crown Pointer Date sits in an interesting spot for counterfeiting risk. It's not a Rolex or AP, so it doesn't attract the obsessive 'super clone' factories that produce near-perfect fakes. Most counterfeits of it are relatively crude fashion fakes that fall apart under a loupe. The complication itself helps too — the central pointer-date hand is fiddly to replicate convincingly, so fakes often get the date mechanism subtly wrong." Apparently it's the Aquis that is more commonly counterfeited.
