Are the sizes quoted the diameter of the main case bezel, or to the outer edge of the button? Trying to work out if the 38 is ok for wife’s wrists.

The sizes quoted are the diameter of the watch crystal. I have the larger 42mm size on my wrist. My wife has the 38mm and it fits her well. In my opinion, the 42 is too wide (big) for a slim wrist. I can't tell you which to choose, but I can say that the sizes are the diameter or the watch crystal. Good luck with your selection!

I have seen a video showing major discrepancies between the scanwatch and polar hr10 belt heart rate measurements, have those issues been resolved?

Yes. I compared a scanwatch with an Apple Watch on the same wrist at the same time and scanwatch was double (and ridiculously high). Withings said to return it and so I did.

Which size would you recommend for a man with an average to large wrist size?

Really just depends if you like a larger or smaller watch face. The band can be easily changed if too large or small. The watch helped confirm that I have AFib, and I'm having procedure to correct it next week. Priceless.

Should this watch breakdown/stop working, I have been told that these cannot be repaired even if sent to the factory! Is this correct?

I've sent two back ,one screen broken after a day the other casing cracked.Both refunded I think they are guaranteed for 3years . As for mechanical break down I don't know you would have to look on the withings site and ask .
