Hmmm..... a watch on either wrist, I hadn't considered that. I'd thought about a discreet fitness tracker (like a whoop, or small fitbit - something that isn't a watch), but not sure I could pull it off - food for thought though!
I'm a fan of the blue strap as well, although the vibrant blue rubber sports strap that came with it is also very pleasing to the eye. I think it will see the most action.
