When wearing a chest strap that collects indoor running data will I see this live on my watch? Also how accurate is this data compared to the watch itself please?

will I see this live on my watch?
Yes.

Heart rate data is potentially more accurate from a chest strap. All other data (like running dynamics) are totally unverifiable, so the question is moot.
