I had the same concern as you, given my wrists are only 6 and a 1/4. I’ve been honestly shocked at how this watch just wears so much slimmer than it’s thickness would lead you to believe - even with the extra bit of material from this strap.
I was a little worried about the thickness when ordered the watch, but as soon as I put it on it was clear it wore really well. Even on my 6 and a quarter inch wrist.
