I have a 6.75" wrist, but I'm also 6'3" 245 lbs. I think my size helps balance out the larger watches like the Legende and Super Avenger. Also, the way the lug ends curve down and the bracelet drops
on these Breitlings, your wrist doesn't have to be as large as it would be to pull off the Omega Planet Ocean 45.5mm bracelet, which sticks out further at the lug ends and doesn't have the same downward curve. So being 47mm isn't the only indication of how it will fit on the wrist.
